  • Multi-statement Table Valued Function vs Inline Table Valued Function

    - by AndyC
    ie: CREATE FUNCTION MyNS.GetUnshippedOrders() RETURNS TABLE AS RETURN SELECT a.SaleId, a.CustomerID, b.Qty FROM Sales.Sales a INNER JOIN Sales.SaleDetail b ON a.SaleId = b.SaleId INNER JOIN Production.Product c ON b.ProductID = c.ProductID WHERE a.ShipDate IS NULL GO versus: CREATE FUNCTION MyNS.GetLastShipped(@CustomerID INT) RETURNS @CustomerOrder TABLE (SaleOrderID INT NOT NULL, CustomerID INT NOT NULL, OrderDate DATETIME NOT NULL, OrderQty INT NOT NULL) AS BEGIN DECLARE @MaxDate DATETIME SELECT @MaxDate = MAX(OrderDate) FROM Sales.SalesOrderHeader WHERE CustomerID = @CustomerID INSERT @CustomerOrder SELECT a.SalesOrderID, a.CustomerID, a.OrderDate, b.OrderQty FROM Sales.SalesOrderHeader a INNER JOIN Sales.SalesOrderHeader b ON a.SalesOrderID = b.SalesOrderID INNER JOIN Production.Product c ON b.ProductID = c.ProductID WHERE a.OrderDate = @MaxDate AND a.CustomerID = @CustomerID RETURN END GO Is there an advantage to using one over the other? Is there certain scenarios when one is better than the other or are the differences purely syntactical? I realise the 2 example queries are doing different things but is there a reason I would write them in that way? Reading about them and the advantages/differences haven't really been explained. Thanks

  • 2d trajectory planning of a spaceship with physics.

    - by egarcia
    I'm implementing a 2D game with ships in space. In order to do it, I'm using LÖVE, which wraps Box2D with Lua. But I believe that my question can be answered by anyone with a greater understanding of physics than myself - so pseudo code is accepted as a response. My problem is that I don't know how to move my spaceships properly on a 2D physics-enabled world. More concretely: A ship of mass m is located at an initial position {x, y}. It has an initial velocity vector of {vx, vy} (can be {0,0}). The objective is a point in {xo,yo}. The ship has to reach the objective having a velocity of {vxo, vyo} (or near it), following the shortest trajectory. There's a function called update(dt) that is called frequently (i.e. 30 times per second). On this function, the ship can modify its position and trajectory, by applying "impulses" to itself. The magnitude of the impulses is binary: you can either apply it in a given direction, or not to apply it at all). In code, it looks like this: def Ship:update(dt) m = self:getMass() x,y = self:getPosition() vx,vy = self.getLinearVelocity() xo,yo = self:getTargetPosition() vxo,vyo = self:getTargetVelocity() thrust = self:getThrust() if(???) angle = ??? self:applyImpulse(math.sin(angle)*thrust, math.cos(angle)*thrust)) end end The first ??? is there to indicate that in some occasions (I guess) it would be better to "not to impulse" and leave the ship "drift". The second ??? part consists on how to calculate the impulse angle on a given dt. We are in space, so we can ignore things like air friction. Although it would be very nice, I'm not looking for someone to code this for me; I put the code there so my problem is clearly understood. What I need is an strategy - a way of attacking this. I know some basic physics, but I'm no expert. For example, does this problem have a name? That sort of thing. Thanks a lot.

  • Sharing a UIView between UIViewControllers in a UITabBarController

    - by Wireless Designs
    Hi all - I have a UIScrollView that houses a gallery of images the user can scroll through. This view needs to be visible on each of three separate UIViewControllers that are housed within a UITabBarController. Right now, I have three separate UIScrollView instances in the UITabBarController subclass, and the controller manages keeping the three synchronized (when a user scrolls the one they can see, programmatically scrolling the other two to match, etc.), which is not ideal. I would like to know if there is a way to work with only ONE instance of the UIScrollView, but have it show up only in the UIViewController that the user is currently interacting with. This would completely eliminate all the synchronization code. Here is basically what I have now in the UITabBarController (which is where all this is currently managed): @interface ScrollerTabBarController : UITabBarController { FirstViewController *firstView; SecondViewController *secondView; ThirdViewController *thirdView; UIScrollView *scrollerOne; UIScrollView *scrollerTwo; UIScrollView *scrollerThree; } @property (nonatomic,retain) IBOutlet FirstViewController *firstView; @property (nonatomic,retain) IBOutlet SecondViewController *secondView; @property (nonatomic,retain) IBOutlet ThirdViewController *thirdView; @property (nonatomic,retain) IBOutlet UIScrollView *scrollerOne; @property (nonatomic,retain) IBOutlet UIScrollView *scrollerTwo; @property (nonatomic,retain) IBOutlet UIScrollView *scrollerThree; @end @implementation ScrollerTabBarController - (void)layoutScroller:(UIScrollView *)scroller {} - (void)scrollToMatch:(UIScrollView *)scroller {} - (void)viewDidLoad { [self layoutScroller:scrollerOne]; [self layoutScroller:scrollerTwo]; [self layoutScroller:scrollerThree]; [scrollerOne setDelegate:self]; [scrollerTwo setDelegate:self]; [scrollerThree setDelegate:self]; [firstView setGallery:scrollerOne]; [secondView setGallery:scrollerTwo]; [thirdView setGallery:scrollerThree]; } - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { [self scrollToMatch:scrollView]; } @end The UITabBarController gets notified (as the scroll view's delegate) when the user scrolls one of the instances, and then calls methods like scrollToMatch: to sync up the other two with the user's choice. Is there something that can be done, using a many-to-one relationship on IBOutlet or something like that, to narrow this down to one instance so I'm not having to manage three scroll views? I tried keeping a single instance and moving the pointer from one view to the next using the UITabBarControllerDelegate methods (calling setGallery:nil on the current and setGallery:scrollerOne on the next each time it changed), but the scroller never moved to the other tabs. Thanks in advance!

  • In NHibernate, how do I combine two DetachedCriteria instances

    - by Trevor
    My scenario is this: I have a base NHibernate query to run of the form (I've coded it using DetachedCriteria , but describe it here using SQL syntax): SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key The user interface to show the results of this join allows the user to specify additional criteria: Say: I.SomeField = 'UserValue'. Now, I need the final load command to be: SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key WHERE I.SomeField = 'UserValue' My problem is: I've created a DetachedCriteria with the 'static' aspect of the query (the top join) and the UI creates a DetachedCriteria with the 'dynamic' component of the query. I need to combine the two into a final query that I can execute on the NHibernate session. DefaultCriteria.Add() takes an ICriterion (which are created using the Expression class, and maybe other classes I don't know of which could be the solution to my problem). Does anyone know how I might do what I want?

  • Entity Framework many-to-many using VB.Net Lambda

    - by bgs264
    Hello, I'm a newbie to StackOverflow so please be kind ;) I'm using Entity Framework in Visual Studio 2010 Beta 2 (.NET framework 4.0 Beta 2). I have created an entity framework .edmx model from my database and I have a handful of many-to-many relationships. A trivial example of my database schema is Roles (ID, Name, Active) Members (ID, DateOfBirth, DateCreated) RoleMembership(RoleID, MemberID) I am now writing the custom role provider (Inheriting System.Configuration.Provider.RoleProvider) and have come to write the implementation of IsUserInRole(username, roleName). The LINQ-to-Entity queries which I wrote, when SQL-Profiled, all produced CROSS JOIN statements when what I want is for them to INNER JOIN. Dim query = From m In dc.Members From r In dc.Roles Where m.ID = 100 And r.Name = "Member" Select m My problem is almost exactly described here: http://stackoverflow.com/questions/553918/entity-framework-and-many-to-many-queries-unusable I'm sure that the solution presented there works well, but whilst I studied Java at uni and I can mostly understand C# I cannot understand this Lambda syntax provided and I need to get a similar example in VB. I've looked around the web for the best part of half a day but I'm not closer to my answer. So please can somebody advise how, in VB, I can construct a LINQ statement which would do this equivalent in SQL: SELECT rm.RoleID FROM RoleMembership rm INNER JOIN Roles r ON r.ID = rm.RoleID INNER JOIN Members m ON m.ID = rm.MemberID WHERE r.Name = 'Member' AND m.ID = 101 I would use this query to see if Member 101 is in Role 3. (I appreciate I probably don't need the join to the Members table in SQL but I imagine in LINQ I'd need to bring in the Member object?) UPDATE: I'm a bit closer by using multiple methods: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim count As Integer Using dc As New CBLModel.CBLEntities Dim persons = dc.Members.Where(AddressOf myTest) count = persons.Count End Using System.Diagnostics.Debugger.Break() End Sub Function myTest(ByVal m As Member) As Boolean Return m.ID = "100" AndAlso m.Roles.Select(AddressOf myRoleTest).Count > 0 End Function Function myRoleTest(ByVal r As Role) As Boolean Return r.Name = "Member" End Function SQL Profiler shows this: SQL:BatchStarting SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] RPC:Completed exec sp_executesql N'SELECT [Extent2].[ID] AS [ID], [Extent2].[Name] AS [Name], [Extent2].[Active] AS [Active] FROM [dbo].[RoleMembership] AS [Extent1] INNER JOIN [dbo].[Roles] AS [Extent2] ON [Extent1].[RoleID] = [Extent2].[ID] WHERE [Extent1].[MemberID] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=100 SQL:BatchCompleted SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] I'm not certain why it is using sp_execsql for the inner join statement and why it's still running a select to select ALL members though. Thanks. UPDATE 2 I've written it by turning the above "multiple methods" into lambda expressions then all into one query, like this: Dim allIDs As String = String.Empty Using dc As New CBLModel.CBLEntities For Each retM In dc.Members.Where(Function(m As Member) m.ID = 100 AndAlso m.Roles.Select(Function(r As Role) r.Name = "Doctor").Count > 0) allIDs &= retM.ID.ToString & ";" Next End Using But it doesn't seem to work: "Doctor" is not a role that exists, I just put it in there for testing purposes, yet "allIDs" still gets set to "100;" The SQL in SQL Profiler this time looks like this: SELECT [Project1].* FROM ( SELECT [Extent1].*, (SELECT COUNT(1) AS [A1] FROM [dbo].[RoleMembership] AS [Extent2] WHERE [Extent1].[ID] = [Extent2].[MemberID]) AS [C1] FROM [dbo].[Members] AS [Extent1] ) AS [Project1] WHERE (100 = [Project1].[ID]) AND ([Project1].[C1] > 0) For brevity I turned the list of all the columns from the Members table into * As you can see it's just ignoring the "Role" query... :/

  • Drupal Views Duplicate values being returned when using a relationship

    - by Linda
    I am having a problem with views. I have a view and am passing it a taxonomy term by name to it. I then have a relationship to a related node. For my output fields I am returning the related Title and related Body. I however have duplicates in my results. I have turned distinct to yes but believe this is working on the nodes being return and not the related node. Any ideas how I can remove the duplicates? Update Below is the query being run when I only get the title SELECT DISTINCT(node.nid) AS nid, node_node_data_field_wine_company.title AS node_node_data_field_wine_company_title, node_node_data_field_wine_company.nid AS node_node_data_field_wine_company_nid FROM node node LEFT JOIN content_type_wine node_data_field_wine_company ON node.vid = node_data_field_wine_company.vid INNER JOIN node node_node_data_field_wine_company ON node_data_field_wine_company.field_wine_company_nid = node_node_data_field_wine_company.nid LEFT JOIN term_node term_node ON node.vid = term_node.vid INNER JOIN term_data term_data ON term_node.tid = term_data.tid WHERE term_data.name = 'test' GROUP BY nid It looks like I should be grouping by node_node_data_field_wine_company_nid or selecting distinct values from there. Any ideas?

  • Selecting info from multiple tables for one unique ID with PHP and MySQL

    - by Mark
    I'm using PHP and MySQL. Is this the best method to select information about "user_1" from four different tables? I know it works, because I have tried it. But is this the preferred method of selecting information from multiple tables for "user_1"? $query = "SELECT table_1.username, table_2.city, table_3.state, table_4.country FROM table_1 JOIN table_2 ON table_1.username=table_2.city JOIN table_3 ON table_1.username=table_3.state JOIN table_4 ON table_1.username=table_4.country WHERE table_1.username = 'user_1'";

  • how to use SQL wildcard % with Queryset extra>select?

    - by tylias
    I'm trying to add weights to search terms I'm using to filter a queryset. Using the '%' wildcard is causing me some problems. I'm using the extra() modifier to add a weight parameter to the queryset, which I will be using to inform a sort ordering. (See http://docs.djangoproject.com/en/1.1/ref/models/querysets/#extra-select-none-where-none-params-none-tables-none-order-by-none-select-params-none ) Here's the gist of the code: def viewname(request) ... exact_matchstrings="" exact_matchstrings.append("(accountprofile.first_name LIKE '" + term + "')") exact_matchstrings.append("(accountprofile.first_name LIKE '" + term + '\%' + "')") extraquerystring = " + ".join(exact_matchstrings) return_queryset = return_queryset.extra( select = { 'match_weight': extraquerystring }, ) The effect I'm going for is that if the search term matches exactly, the weight associated with the record is 2, but if the term merely starts with the search term and isn't an exact match, the weight is 1. (for example, if 'term' = 'Jon', an entry with first_name='Jon' gets a weight of 2 but an entry with an entry with first_name = 'Jonathan' gets a weight of 1.) I can test the statement in SQL and it seems to work well enough. If I make this SQL query from the mysql shell, no problem: select (first_name like "Carl") + (first_name like "Car%") from accountprofile; But trying to run it via the extra() modifier in my view code and evaluating the resulting queryset gives me the following error: Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 68, in __repr__ data = list(self[:REPR_OUTPUT_SIZE + 1]) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 83, in __len__ self._result_cache.extend(list(self._iter)) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 238, in iterator for row in self.query.results_iter(): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 287, in results_iter for rows in self.execute_sql(MULTI): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 2369, in execute_sql cursor.execute(sql, params) File "/usr/local/lib/python2.6/dist-packages/django/db/backends/util.py", line 22, in execute sql = self.db.ops.last_executed_query(self.cursor, sql, params) File "/usr/local/lib/python2.6/dist-packages/django/db/backends/__init__.py", line 217, in last_executed_query return smart_unicode(sql) % u_params ValueError: unsupported format character ''' (0x27) at index 309 I've tried it escaping and not escaping % wildcard but that doesn't solve the problem. Doesn't seem to affect it at all, really. Any ideas?

  • Fluent NHibernate - How to map a non nullable foreign key that exists in two joined tables

    - by vakman
    I'm mapping a set of membership classes for my application using Fluent NHibernate. I'm mapping the classes to the asp.net membership database structure. The database schema relevant to the problem looks like this: ASPNET_USERS UserId PK ApplicationId FK NOT NULL other user columns ... ASPNET_MEMBERSHIP UserId PK,FK ApplicationID FK NOT NULL other membership columns... There is a one to one relationship between these two tables. I'm attempting to join the two tables together and map data from both tables to a single 'User' entity which looks like this: public class User { public virtual Guid Id { get; set; } public virtual Guid ApplicationId { get; set; } // other properties to be mapped from aspnetuser/membership tables ... My mapping file is as follows: public class UserMap : ClassMap<User> { public UserMap() { Table("aspnet_Users"); Id(user => user.Id).Column("UserId").GeneratedBy.GuidComb(); Map(user => user.ApplicationId); // other user mappings Join("aspnet_Membership", join => { join.KeyColumn("UserId"); join.Map(user => user.ApplicationId); // Map other things from membership to 'User' class } } } If I try to run with the code above I get a FluentConfiguration exception Tried to add property 'ApplicationId' when already added. If I remove the line "Map(user = user.ApplicationId);" or change it to "Map(user = user.ApplicationId).Not.Update().Not.Insert();" then the application runs but I get the following exception when trying to insert a new user: Cannot insert the value NULL into column 'ApplicationId', table 'ASPNETUsers_Dev.dbo.aspnet_Users'; column does not allow nulls. INSERT fails. The statement has been terminated. And if I leave the .Map(user = user.ApplicationId) as it originally was and make either of those changes to the join.Map(user = user.ApplicationId) then I get the same exception above except of course the exception is related to an insert into the aspnet_Membership table So... how do I do this kind of mapping assuming I can't change my database schema?

  • SQL Server 2008 ContainsTable, CTE, and Paging

    - by David Murdoch
    I'd like to perform efficient paging using containstable. The following query selects the top 10 ranked results from my database using containstable when searching for a name (first or last) that begins with "Joh". DECLARE @Limit int; SET @Limit = 10; SELECT TOP @Limit c.ChildID, c.PersonID, c.DOB, c.Gender FROM [Person].[vFullName] AS v INNER JOIN CONTAINSTABLE( [Person].[vFullName], (FullName), IS ABOUT ( "Joh*" WEIGHT (.4), "Joh" WEIGHT (.6)) ) AS k3 ON v.PersonID = k3.[KEY] JOIN [Child].[Details] c ON c.PersonID = v.PersonID JOIN [Person].[Details] p ON p.PersonID = c.PersonID ORDER BY k3.RANK DESC, FullName ASC, p.Active DESC, c.ChildID ASC I'd like to combine it with the following CTE which returns the 10th-20th results ordered by ChildID (the primary key): DECLARE @Start int; DECLARE @Limit int; SET @Start = 10; SET @Limit = 10; WITH ChildEntities AS ( SELECT ROW_NUMBER() OVER (ORDER BY ChildID) AS Row, ChildID FROM Child.Details ) SELECT c.ChildID, c.PersonID, c.DOB, c.Gender FROM ChildEntities cte INNER JOIN Child.Details c ON cte.ChildID = c.ChildID WHERE cte.Row BETWEEN @Start+1 AND @Start+@Limit ORDER BY cte.Row ASC

  • Nhibernate one-to-many with table per subclass

    - by Wayne
    I am customizing N2CMS's database structure, and met with an issue. The two classes are listed below. public class Customer : ContentItem { public IList<License> Licenses { get; set; } } public class License : ContentItem { public Customer Customer { get; set; } } The nhibernate mapping are as follows. <class name="N2.ContentItem,N2" table="n2item"> <cache usage="read-write" /> <id name="ID" column="ID" type="Int32" unsaved-value="0" access="property"> <generator class="native" /> </id> <discriminator column="Type" type="String" /> </class> <subclass name="My.Customer,My" extends="N2.ContentItem,N2" discriminator-value="Customer"> <join table="Customer"> <key column="ItemID" /> <bag name="Licenses" generic="true" inverse="true"> <key column="CustomerID" /> <one-to-many class="My.License,My"/> </bag> </join> </subclass> <subclass name="My.License,My" extends="N2.ContentItem,N2" discriminator-value="License"> <join table="License" fetch="select"> <key column="ItemID" /> <many-to-one name="Customer" column="CustomerID" class="My.Customer,My" not-null="false" /> </join> </subclass> Then, when get an instance of Customer, the customer.Licenses is always empty, but actually there are licenses in the database for the customer. When I check the nhibernate log file, I find that the SQL query is like: SELECT licenses0_.CustomerID as CustomerID1_, licenses0_.ID as ID1_, licenses0_.ID as ID2_0_, licenses0_1_.CustomerID as CustomerID7_0_, FROM n2item licenses0_ inner join License licenses0_1_ on licenses0_.ID = licenses0_1_.ItemID WHERE licenses0_.CustomerID = 12 /* @p0 */ It seems that nhibernate believes that the CustomerID is in the 'n2item' table. I don't know why, but to make it work, I think the SQL should be something like this. SELECT licenses0_.ID as ID1_, licenses0_.ID as ID2_0_, licenses0_1_.CustomerID as CustomerID7_0_, FROM n2item licenses0_ inner join License licenses0_1_ on licenses0_.ID = licenses0_1_.ItemID WHERE licenses0_1_.CustomerID = 12 /* @p0 */ Could any one point out what's wrong with my mappings? And how can I get the correct licenses of one customer? Thanks in advance.

SELECT u.Id as Id, u.Login as Login, u.FirstName as FirstName, u.LastName as LastName, gm.UserGroupId_FK as UserGroupId, inner.Data1, inner.Data2, inner.Data3 FROM dbo.User u inner join dbo.GroupMember gm on u.Id = gm.UserAnchorId_FK left join ( SELECT di.UserAnchorId_FK, sum(di.Data1) as Data1, sum(di.Data2) as Data2, sum(di.Data3) as Data3 FROM dbo.DailyInfo di WHERE di.Date between '2009-04-01' and '2009-06-01' GROUP BY di.UserAnchorId_FK ) inner ON inner.UserAnchorId_FK = u.Id WHERE gm.UserGroupId_FK = 195 Attempts so far have included mapping 'User' and 'DailyInfo' classes (my entities) and making a DailyInfo object a property of the User object. However, how to map the foreign key relationship between them is still a mystery, ie <one-to-one></one-to-one> <one-to-many></one-to-many> <generator class="foreign"><param name="property">Id</param></generator> (!) Solutions on the web are generally to do with subqueries within a WHERE clause, however I need to left join on this subquery instead to ensure NULL values are returned for rows that do not join. I have the feeling that I should be using a Criteria for the outer query, then forming a 'join' with a DetachedCriteria to represent the subquery?

  • How can parallelism affect number of results?

    - by spender
    I have a fairly complex query that looks something like this: create table Items(SomeOtherTableID int,SomeField int) create table SomeOtherTable(Id int,GroupID int) with cte1 as ( select SomeOtherTableID,COUNT(*) SubItemCount from Items t where t.SomeField is not null group by SomeOtherTableID ),cte2 as ( select tc.SomeOtherTableID,ROW_NUMBER() over (partition by a.GroupID order by tc.SubItemCount desc) SubItemRank from Items t inner join SomeOtherTable a on a.Id=t.SomeOtherTableID inner join cte1 tc on tc.SomeOtherTableID=t.SomeOtherTableID where t.SomeField is not null ),cte3 as ( select SomeOtherTableID from cte2 where SubItemRank=1 ) select * from cte3 t1 inner join cte3 t2 on t1.SomeOtherTableID<t2.SomeOtherTableID option (maxdop 1) The query is such that cte3 is filled with 6222 distinct results. In the final select, I am performing a cross join on cte3 with itself, (so that I can compare every value in the table with every other value in the table at a later point). Notice the final line : option (maxdop 1) Apparently, this switches off parallelism. So, with 6222 results rows in cte3, I would expect (6222*6221)/2, or 19353531 results in the subsequent cross joining select, and with the final maxdop line in place, that is indeed the case. However, when I remove the maxdop line, the number of results jumps to 19380454. I have 4 cores on my dev box. WTF? Can anyone explain why this is? Do I need to reconsider previous queries that cross join in this way?

  • Problem adding subviews (UIButtons) to subclass of UIImageView

    - by samfu_1
    I'm adding a custom button/keypad to my application. Thus far, I have a UIImageView subclass that contains an animation that slides it from the bottom of the screen, and then back down when the user no longer needs it. I'm having trouble adding UIButtons to this UIImageView, however. Since this is a subclass of UIView, I'm attempting to add buttons to my view via the initWithFrame: method. (slideDown method is the added animation) in my UIImageView Subclass, I have a UIButton ivar object added: -(id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame: frame]) { UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect]; button.frame = CGRectMake(16.0, 20.0, 50.0, 50.0); [button setTitle: @"Go" forState: UIControlStateNormal]; [button addTarget: self action: @selector(slideDown) forControlEvents: UIControlEventTouchUpInside]; self.button1 = button; [self addSubview: button1]; NSLog(@"Button added"); } return self; } In my view controller, I instantiate my UIIMageView Subclass in the -(void)viewDidLoad: method as follows: -(void)viewDidLoad { //other objects init'ed ButtonPad *customPad = [[ButtonPad alloc] initWithImage: [UIImage imageNamed: @"ButtonPad.png"]]; customPad.frame = CGRectMake(0.0, 480.0, 320.0, 300.0); self.buttonPad = customPad; [self.view addSubview: buttonPad]; [customPad release]; [super viewDidLoad]; } My current app allows the view to slide up and down off of the screen without any problems. However, the button never appears. I have also tried adding the button to my buttonPad object by instantiating & adding it as a subView to the buttonPad in my view controller file. This worked... but it didn't allow the button to function. I am wondering: A.) Is it appropriate to add buttons or any subview for that matter to the UIView initWithFrame: method or should I be adding these subviews as a subview to my buttonPad in the view Controller file? B.) Since I am creating a custom button/keypad, am i following a valid approach by using a normal UIViewController or should I be using something like a modal view Controller? ( I have little knowledge about these.)

  • UITableView not getting populated

    - by jayshree430
    Hi. I have a peculiar problem. I created a normal Objective c class called SampleTable. I then extended UITableView instead of NSObject. Then in the initWithFrame constructor i initialized the table. I also made a NSMutableArray object for the datasource. I also conformed UITableViewDelegate and UITableViewDatasource. I have overridden the necessary methods also. Now i made an object of this class in another class, and added the object as a subview. The tableView is getting drawn according to the CGRectMake() coordinates i gave to the initWithFrame constructor. But it is not getting populated with the data. I dnt know what the problem is . Can plz someone help me. SampleTable.h #import @interface SampleTable : UITableView { NSMutableArray *ItemArray; } @property (nonatomic,retain) NSMutableArray *ItemArray; -(NSMutableArray *) displayItemArray; @end SampleTable.m #import "SampleTable.h" @implementation SampleTable @synthesize ItemArray; -(id)initWithFrame:(CGRect)frm { [super initWithFrame:frm]; self.delegate=self; self.dataSource=self; [self reloadData]; return self; } -(NSMutableArray *) displayItemArray { if(ItemArray==nil) { ItemArray=[[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"5",nil]; } return ItemArray; } (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [ItemArray count]; } (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell= [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell==nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; [cell autorelease]; } NSString *temp=[self.ItemArray objectAtIndex:indexPath.row]; cell.textLabel.text = temp; return cell; } (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"didselect"); } -(void) dealloc { [ItemArray release]; [super dealloc]; } @end

  • MySQL Full-Text Search Across Multiple Tables - Quick/Long Solution?

    - by Kerry
    Hello all, I have been doing a bit of research on full-text searches as we realized a series of LIKE statements are terrible. My first find was MySQL full-text searches. I tried to implement this and it worked on one table, failed when I was trying to join multiple tables, and so I consulted stackoverflow's articles (look at the end for a list of the ones I've been to) I didn't see anything that clearly answered my questions. I'm trying to get this done literally in an hour or two (quick solution) but I also want to do a better long term solution. Here is my query: SELECT a.`product_id`, a.`name`, a.`slug`, a.`description`, b.`list_price`, b.`price`, c.`image`, c.`swatch`, e.`name` AS industry FROM `products` AS a LEFT JOIN `website_products` AS b ON (a.`product_id` = b.`product_id`) LEFT JOIN ( SELECT `product_id`, `image`, `swatch` FROM `product_images` WHERE `sequence` = 0) AS c ON (a.`product_id` = c.`product_id`) LEFT JOIN `brands` AS d ON (a.`brand_id` = d.`brand_id`) INNER JOIN `industries` AS e ON (a.`industry_id` = e.`industry_id`) WHERE b.`website_id` = 96 AND b.`status` = 1 AND b.`active` = 1 AND MATCH( a.`name`, a.`sku`, a.`description`, d.`name` ) AGAINST ( 'ashley sofa' ) GROUP BY a.`product_id` ORDER BY b.`sequence` LIMIT 0, 9 The error I get is: Incorrect arguments to MATCH If I remove d.name from the MATCH statement it works. I have a full-text index on that column. I saw one of the articles say to use an OR MATCH for this table, but won't that lose the effectiveness of being able to rank them together or match them properly? Other places said to use UNIONs but I don't know how to do that properly. Any advice would be greatly appreciated. In the idea of a long term solution it seems that either Sphinx or Lucene is best. Now by no means and I a MySQL guru, and I heard that Lucene is a bit more complicated to setup, any recommendations or directions would be great.

  • MySQL Query GROUP_CONCAT Over Multiple Rows

    - by PeteGO
    I'm getting name and address data out of generic question / answer data to create some kind of normalised reporting database. The query I've got uses group_concat and works for individual sets of questions but not for multiple sets. I've tried to simplify what I'm doing by using just forename and surname and just 3 records, 2 for 1 person and 1 for another. In reality though there are more than 300,000 records. Example of results with qs.Id = 1. QuestionSetId Forename Surname ------------------------------------------------------- 1 Bob Jones Example of results with qs.Id IN (1, 2, 3). QuestionSetId Forename Surname ------------------------------------------------------- 3 Bob,Bob,Frank Jones,Jones,Smith What I would like to see for qs.Id IN (1, 2, 3). QuestionSetId Forename Surname ------------------------------------------------------- 1 Bob Jones 2 Bob Jones 3 Frank Smith So how can I make the 2nd example return a separate row for each set of name and address information? I realise the current way the data is stored is "questionable" but I cannot change the way the data is stored. I can get sets of individual answers but not sure how to combine the others. My simplified Schema that I cannot change: CREATE TABLE StaticQuestion ( Id INT NOT NULL, StaticText VARCHAR(500) NOT NULL); CREATE TABLE Question ( Id INT NOT NULL, Text VARCHAR(500) NOT NULL); CREATE TABLE StaticQuestionQuestionLink ( Id INT NOT NULL, StaticQuestionId INT NOT NULL, QuestionId INT NOT NULL, DateEffective DATETIME NOT NULL); CREATE TABLE Answer ( Id INT NOT NULL, Text VARCHAR(500) NOT NULL); CREATE TABLE QuestionSet ( Id INT NOT NULL, DateEffective DATETIME NOT NULL); CREATE TABLE QuestionAnswerLink ( Id INT NOT NULL, QuestionSetId INT NOT NULL, QuestionId INT NOT NULL, AnswerId INT NOT NULL, StaticQuestionId INT NOT NULL); Some example data for only forename and surname. INSERT INTO StaticQuestion (Id, StaticText) VALUES (1, 'FirstName'), (2, 'LastName'); INSERT INTO Question (Id, Text) VALUES (1, 'What is your first name?'), (2, 'What is your forename?'), (3, 'What is your Surname?'); INSERT INTO StaticQuestionQuestionLink (Id, StaticQuestionId, QuestionId, DateEffective) VALUES (1, 1, 1, '2001-01-01'), (2, 1, 2, '2008-08-08'), (3, 2, 3, '2001-01-01'); INSERT INTO Answer (Id, Text) VALUES (1, 'Bob'), (2, 'Jones'), (3, 'Bob'), (4, 'Jones'), (5, 'Frank'), (6, 'Smith'); INSERT INTO QuestionSet (Id, DateEffective) VALUES (1, '2002-03-25'), (2, '2009-05-05'), (3, '2009-08-06'); INSERT INTO QuestionAnswerLink (Id, QuestionSetId, QuestionId, AnswerId, StaticQuestionId) VALUES (1, 1, 1, 1, 1), (2, 1, 3, 2, 2), (3, 2, 2, 3, 1), (4, 2, 3, 4, 2), (5, 3, 2, 5, 1), (6, 3, 3, 6, 2); Just in case SQLFiddle is down here are the 3 queries from the examples I've linked to: 1: - working query but only on 1 set of data. SELECT MAX(QuestionSetId) AS QuestionSetId, GROUP_CONCAT(Forename) AS Forename, GROUP_CONCAT(Surname) AS Surname FROM (SELECT x.QuestionSetId, CASE x.StaticQuestionId WHEN 1 THEN Text END AS Forename, CASE x.StaticQuestionId WHEN 2 THEN Text END AS Surname FROM (SELECT (SELECT link.StaticQuestionId FROM StaticQuestionQuestionLink link WHERE link.Id = qa.QuestionId AND link.DateEffective <= qs.DateEffective AND link.StaticQuestionId IN (1, 2) ORDER BY link.DateEffective DESC LIMIT 1) AS StaticQuestionId, a.Text, qa.QuestionSetId FROM QuestionSet qs INNER JOIN QuestionAnswerLink qa ON qs.Id = qa.QuestionSetId INNER JOIN Answer a ON qa.AnswerId = a.Id WHERE qs.Id IN (1)) x) y 2: - working query but undesired results on multiple sets of data. SELECT MAX(QuestionSetId) AS QuestionSetId, GROUP_CONCAT(Forename) AS Forename, GROUP_CONCAT(Surname) AS Surname FROM (SELECT x.QuestionSetId, CASE x.StaticQuestionId WHEN 1 THEN Text END AS Forename, CASE x.StaticQuestionId WHEN 2 THEN Text END AS Surname FROM (SELECT (SELECT link.StaticQuestionId FROM StaticQuestionQuestionLink link WHERE link.Id = qa.QuestionId AND link.DateEffective <= qs.DateEffective AND link.StaticQuestionId IN (1, 2) ORDER BY link.DateEffective DESC LIMIT 1) AS StaticQuestionId, a.Text, qa.QuestionSetId FROM QuestionSet qs INNER JOIN QuestionAnswerLink qa ON qs.Id = qa.QuestionSetId INNER JOIN Answer a ON qa.AnswerId = a.Id WHERE qs.Id IN (1, 2, 3)) x) y 3: - working query on multiple sets of data only on 1 field (answer) though.

  • Help finding longest non-repeating path through connected nodes - Python

    - by Jordan Magnuson
    I've been working on this for a couple of days now without success. Basically, I have a bunch of nodes arranged in a 2D matrix. Every node has four neighbors, except for the nodes on the sides and corners of the matrix, which have 3 and 2 neighbors, respectively. Imagine a bunch of square cards laid out side by side in a rectangular area--the project is actually simulating a sort of card/board game. Each node may or may not be connected to the nodes around it. Each node has a function (get_connections()), that returns the nodes immediately around it that it is connected to (so anywhere from 0 to 4 nodes are returned). Each node also has an "index" property, that contains it's position on the board matrix (eg '1, 4' - row 1, col 4). What I am trying to do is find the longest non-repeating path of connected nodes given a particular "start" node. I've uploaded a couple of images that should give a good idea of what I'm trying to do: In both images, the highlighted red cards are supposedly the longest path of connected cards containing the most upper-left card. However, you can see in both images that a couple of cards that should be in the path have been left out (Romania and Maldova in the first image, Greece and Turkey in the second) Here's the recursive function that I am using currently to find the longest path, given a starting node/card: def get_longest_trip(self, board, processed_connections = list(), processed_countries = list()): #Append this country to the processed countries list, #so we don't re-double over it processed_countries.append(self) possible_trips = dict() if self.get_connections(board): for i, card in enumerate(self.get_connections(board)): if card not in processed_countries: processed_connections.append((self, card)) possible_trips[i] = card.get_longest_trip(board, processed_connections, processed_countries) if possible_trips: longest_trip = [] for i, trip in possible_trips.iteritems(): trip_length = len(trip) if trip_length > len(longest_trip): longest_trip = trip longest_trip.append(self) return longest_trip else: print card_list = [] card_list.append(self) return card_list else: #If no connections from start_card, just return the start card #as the longest trip card_list = [] card_list.append(board.start_card) return card_list The problem here has to do with the processed_countries list: if you look at my first screenshot, you can see that what has happened is that when Ukraine came around, it looked at its two possible choices for longest path (Maldova-Romania, or Turkey, Bulgaria), saw that they were both equal, and chose one indiscriminantly. Now when Hungary comes around, it can't attempt to make a path through Romania (where the longest path would actually be), because Romania has been added to the processed_countries list by Ukraine. Any help on this is EXTREMELY appreciated. If you can find me a solution to this, recursive or not, I'd be happy to donate some $$ to you. I've uploaded my full source code (Python 2.6, Pygame 1.9 required) to: http://www.necessarygames.com/junk/planes_trains.zip The relevant code is in src/main.py, which is all set to run.

  • SQL -- How to combine three SELECT statements with very tricky requirements

    - by Frederick
    I have a SQL query with three SELECT statements. A picture of the data tables generated by these three select statements is located at www.britestudent.com/pub/1.png. Each of the three data tables have identical columns. I want to combine these three tables into one table such that: (1) All rows in top table (Table1) are always included. (2) Rows in the middle table (Table2) are included only when the values in column1 (UserName) and column4 (CourseName) do not match with any row from Table1. Both columns need to match for the row in Table2 to not be included. (3) Rows in the bottom table (Table3) are included only when the value in column4 (CourseName) is not already in any row of the results from combining Table1 and Table2. I have had success in implementing (1) and (2) with an SQL query like this: SELECT DISTINCT UserName AS UserName, MAX(AmountUsed) AS AmountUsed, MAX(AnsweredCorrectly) AS AnsweredCorrectly, CourseName, MAX(course_code) AS course_code, MAX(NoOfQuestionsInCourse) AS NoOfQuestionsInCourse, MAX(NoOfQuestionSetsInCourse) AS NoOfQuestionSetsInCourse FROM ( "SELECT statement 1" UNION "SELECT statement 2" ) dt_derivedTable_1 GROUP BY CourseName, UserName Where "SELECT statement 1" is the query that generates Table1 and "SELECT statement 2" is the query that generates Table2. A picture of the data table generated by this query is located at www.britestudent.com/pub/2.png. I can get away with using the MAX() function because values in the AmountUsed and AnsweredCorrectly columns in Table1 will always be larger than those in Table2 (and they are identical in the last three columns of both tables). What I fail at is implementing (3). Any suggestions on how to do this will be appreciated. It is tricky because the UserName values in Table3 are null, and because the CourseName values in the combined Table1 and Table2 results are not unique (but they are unique in Table3). After implementing (3), the final table should look like the table in picture 2.png with the addition of the last row from Table3 (the row with the CourseName value starting with "4. Klasse..." I have tried to implement (3) using another derived table using SELECT, MAX() and UNION, but I could not get it to work. Below is my full SQL query with the lines from this failed attempt to implement (3) commented out.

  • Advice on optimzing speed for a Stored Procedure that uses Views

    - by Belliez
    Based on a previous question and with a lot of help from Damir Sudarevic (thanks) I have the following sql code which works great but is very slow. Can anyone suggest how I can speed this up and optimise for speed. I am now using SQL Server Express 2008 (not 2005 as per my original question). What this code does is retrieves parameters and their associated values from several tables and rotates the table in a form that can be easily compared. Its great for one of two rows of data but now I am testing with 100 rows and to run GetJobParameters takes over 7 minutes to complete? Any advice is gratefully accepted, thank you in advanced. /*********************************************************************************************** ** CREATE A VIEW (VIRTUAL TABLE) TO ALLOW EASIER RETREIVAL OF PARMETERS ************************************************************************************************/ CREATE VIEW dbo.vParameters AS SELECT m.MachineID AS [Machine ID] ,j.JobID AS [Job ID] ,p.ParamID AS [Param ID] ,t.ParamTypeID AS [Param Type ID] ,m.Name AS [Machine Name] ,j.Name AS [Job Name] ,t.Name AS [Param Type Name] ,t.JobDataType AS [Job DataType] ,x.Value AS [Measurement Value] ,x.Unit AS [Unit] ,y.Value AS [JobDataType] FROM dbo.Machines AS m JOIN dbo.JobFiles AS j ON j.MachineID = m.MachineID JOIN dbo.JobParams AS p ON p.JobFileID = j.JobID JOIN dbo.JobParamType AS t ON t.ParamTypeID = p.ParamTypeID LEFT JOIN dbo.JobMeasurement AS x ON x.ParamID = p.ParamID LEFT JOIN dbo.JobTrait AS y ON y.ParamID = p.ParamID GO -- Step 2 CREATE VIEW dbo.vJobValues AS SELECT [Job Name] ,[Param Type Name] ,COALESCE(cast([Measurement Value] AS varchar(50)), [JobDataType]) AS [Val] FROM dbo.vParameters GO /*********************************************************************************************** ** GET JOB PARMETERS FROM THE VIEW JUST CREATED ************************************************************************************************/ CREATE PROCEDURE GetJobParameters AS -- Step 3 DECLARE @Params TABLE ( id int IDENTITY (1,1) ,ParamName varchar(50) ); INSERT INTO @Params (ParamName) SELECT DISTINCT [Name] FROM dbo.JobParamType -- Step 4 DECLARE @qw TABLE( id int IDENTITY (1,1) , txt nchar(300) ) INSERT INTO @qw (txt) SELECT 'SELECT' UNION SELECT '[Job Name]' ; INSERT INTO @qw (txt) SELECT ',MAX(CASE [Param Type Name] WHEN ''' + ParamName + ''' THEN Val ELSE NULL END) AS [' + ParamName + ']' FROM @Params ORDER BY id; INSERT INTO @qw (txt) SELECT 'FROM dbo.vJobValues' UNION SELECT 'GROUP BY [Job Name]' UNION SELECT 'ORDER BY [Job Name]'; -- Step 5 --SELECT txt FROM @qw DECLARE @sql_output VARCHAR (MAX) SET @sql_output = '' -- NULL + '' = NULL, so we need to have a seed SELECT @sql_output = -- string to avoid losing the first line.
