  • linq Multiple Where based on conditions.

    - by Bathan
    I want to query a table with some conditions based on user input. I wrote this : IQueryable turnoQuery = dc.Turno; if (helper.FechaUltimaCitaDesde != DateTime.MinValue) { turnoQuery = turnoQuery.Where(t => t.TurnoFecha >= helper.FechaUltimaCitaDesde); } if (helper.FechaUltimaCitaHasta != DateTime.MinValue) { turnoQuery = turnoQuery.Where(t => t.TurnoFecha <= helper.FechaUltimaCitaHasta); } if (helper.SoloCitasConsumidas) { turnoQuery = turnoQuery.Where(t => t.Estado == Convert.ToInt32(EnmEstadoDelTurno.Consumido)); } else if(helper.AnuladoresDeCitas) { turnoQuery = turnoQuery.Where(t => t.Estado == Convert.ToInt32(EnmEstadoDelTurno.Cancelado) || t.Estado == Convert.ToInt32(EnmEstadoDelTurno.Ausente)); } The problem I'm having is that the "where" clause gets stepped over with the last one. Whats the correct way to do something like this on LINQ? The "helper" object is a custom class storing the user input dates for this example.

  • How do I specify a null relation in SQLAlchemy?

    - by Jesse
    Not sure what the correct title for this question should be. I have the following schema: Matters have a one-many relationship to WorkItems. WorkItems have a one-one (or one-zero) relationship to LineItems. I am trying to create the following relation between Matters and WorkItems Matter.unbilled_work_items = orm.relation(WorkItem, primaryjoin = (Matter.id == WorkItem.matter_id) and (WorkItem.line_item_id == None), foreign_keys = [WorkItem.matter_id, WorkItem.line_item_id], viewonly=True ) This throws: AttributeError: '_Null' object has no attribute 'table' That seems to be saying that the second clause in the primaryjoin returns an object of type _Null, but it seems to be expecting something with a "table" attribute. This seems like it should be pretty straightforward to me, am I missing something obvious?

  • Why is this postgresql query so slow?

    - by user315975
    I'm no database expert, but I have enough knowledge to get myself into trouble, as is the case here. This query SELECT DISTINCT p.* FROM points p, areas a, contacts c WHERE ( p.latitude > 43.6511659465 AND p.latitude < 43.6711659465 AND p.longitude > -79.4677941889 AND p.longitude < -79.4477941889) AND p.resource_type = 'Contact' AND c.user_id = 6 is extremely slow. The points table has fewer than 2000 records, but it takes about 8 seconds to execute. There are indexes on the latitude and longitude columns. Removing the clause concering the resource_type and user_id make no difference. The latitude and longitude fields are both formatted as number(15,10) -- I need the precision for some calculations. There are many, many other queries in this project where points are compared, but no execution time problems. What's going on?

  • Default Values Specflow Step Definitions

    - by Gavin Osborn
    I'm starting out in the world of SpecFlow and I have come across my first problem. In terms of keeping my code DRY I'd like to do the following: Have two scenarios: Given I am on a product page And myfield equals todays date Then... Given I am on a product page And myfield equals todays date plus 4 days Then... I was hoping to use the following Step Definition to cover both variants of my And clause: [Given(@"myfield equals todays date(?: (plus|minus) (\d+) days)?")] public void MyfieldEqualsTodaysDate(string direction, int? days) { //do stuff } However I keep getting exceptions when SpecFlow tries to parse the int? param. I've checked the regular expression and it definitely parses the scenario as expected. I'm aware that I could so something as crude as method overloading etc, I was just wondering if SpecFlow supported the idea of default parameter values, or indeed another way to achieve the same effect. Many Thanks

  • Warning vs. error

    - by Samuel
    I had an annoying issue, getting a "Possible loss of precision" error when compiling my Java program on BlueJ (But from what i read this isn't connected to a specific IDE). I was surprised by the fact that the compiler told me there is a possible loss of precision and wouldnt let me compile/run the program. Why is this an error and not a warning saying you might loose precision here, if you don't want that change your code? The program runs just fine when i drop the float values, it wouldn't matter since there is no point (e.g [143.08, 475.015]) on my screen. On the other hand when i loop through an ArrayList and in this loop i have an if clause removing elements from the ArrayList it runs fine, just throws an error and doesn't display the ArrayList [used for drawing circles] for a fraction of a second. This appears to me as a severe error but doesn't cause (hardly) any troubles, while i wouldn't want to have such a thing in my code at all. What's the boundary?

    i have 2 queries in vb.net with an if clause - if x=0 then insert into table1 else update table1 both queries have 5 fields. now what i want to do is after this insert or update takes place, i need to look at this inserted/updated record and compare it with another table (table2). Especially for update, i have 5 fields in both tables. if any of the 5 fields dont match with table2, then i insert a new record in table 2 which is the updated record in table 1. how can i do this?

  • Get a list of events owned by a facebook page

    - by Tom Wright
    Does anyone know how I can get a list of events owned (created) by a Facebook page? I seem to be able to use the "graph api" to generate a list of the events an entity is attending. I also looked at FQL, but it seems to require that the 'where' clause is an indexable field (and, naturally, the id is the only indexable field). For bonus points, we'd be able to do this without any authentication. (Though I'm resigned to the fact that I'm likely going to need at least a permanent access_token.) If anyone know how to do this I'd be eternally grateful.

  • How can I configure Xcode to put '{' where I want it in generated files

    - by djhworld
    I know this is a fairly contentious issue amongst programmers, but when developing I like my IDE to position the opening curly bracket underneath the method/interface/control declaration, for illustrative purposes: - This is how Xcode automatically generates skeleton methods with the { at the end: - -(void) isTrue:(BOOL)input { if(input) { return YES; } else { return NO; } } This is how I like to lay out my code (which I believe is called the Allman style): - -(void) isTrue:(BOOL)input { if(input) { return YES; } else { return NO; } } I'm just wondering if there's any configuration switch in Xcode to enable this style of development? It's really annoying when typing out if/else statements as it tends to auto-complete the else clause with the { at the end of the line which just looks silly if you like developing with them underneath. Or am I being unreasonable? Is Objective-C supposed to adhere to a standard defined by Apple?

  • JPA and aggregate functions. How do I use the result of the query?

    - by Bogdan
    Hey guys, I'm new to ORM stuff and I need some help understanding something. Let's assume I have the following standard SQL query: SELECT *, COUNT(test.testId) AS noTests FROM inspection LEFT JOIN test ON inspection.inspId = test.inspId GROUP BY inspection.inspId which I want to use in JPA. I have an Inspection entity with a one-to-many relationship to a Test entity. (an inspection has many tests) I tried writing this in JPQL: Query query = em.createQuery("SELECT insp, COUNT(???what???) FROM Inspection insp LEFT JOIN insp.testList " + "GROUP BY insp.inspId"); 1) How do I write the COUNT clause? I'd have to apply count to elements from the test table but testList is a collection, so I can't do smth like COUNT(insp.testList.testId) 2) Assuming 1 is resolved, what type of object will be returned. It will definitely not be an Inspection object... How do I use the result?

  • Grails - Need to restrict fetched rows based on condition on join table

    - by sector7
    Hi guys, I have these two domains Car and Driver which have many-to-many relationship. This association is defined in table tblCarsDrivers which has, not surprisingly, primary keys of both the tables BUT additionally also has a new boolean field deleted. Herein lies the problem. When I find/get query on domain Car, I am fetched all related drivers irrespective of their deleted status in tblCarsDrivers, which is expected. I need to put a clause/constraint to exclude the deleted drivers from the list of fetched records. PS: I tried using an association domain CarDriver in joinTable name but that seems not to work. Apparently it expects only table names, not maps. PPS: I know its unnatural to have any other fields besides the mapping keys in mapping table but this is how I got it and it cant be changed. Car domain is defined as such - class Car { Integer id String name static hasMany = [drivers:Driver] static mapping = { table 'tblCars' version false drivers joinTable:[name: 'tblCarsDrivers',column:'driverid',key:'carid'] } } Thanks!

  • How to remove duplicate records in a table?

    - by Mason Wheeler
    I've got a table in a testing DB that someone apparently got a little too trigger-happy on when running INSERT scripts to set it up. The schema looks like this: ID UNIQUEIDENTIFIER TYPE_INT SMALLINT SYSTEM_VALUE SMALLINT NAME VARCHAR MAPPED_VALUE VARCHAR It's supposed to have a few dozen rows. It has about 200,000, most of which are duplicates in which TYPE_INT, SYSTEM_VALUE, NAME and MAPPED_VALUE are all identical and ID is not. Now, I could probably make a script to clean this up that creates a temporary table in memory, uses INSERT .. SELECT DISTINCT to grab all the unique values, TRUNCATE the original table and then copy everything back. But is there a simpler way to do it, like a DELETE query with something special in the WHERE clause?

  • Does having a longer string in a SQL Like expression allow hinder or help query executing speed?

    - by Allain Lalonde
    I have a db query that'll cause a full table scan using a like clause and came upon a question I was curious about... Which of the following should run faster in Mysql or would they both run at the same speed? Benchmarking might answer it in my case, but I'd like to know the why of the answer. The column being filtered contains a couple thousand characters if that's important. SELECT * FROM users WHERE data LIKE '%=12345%' or SELECT * FROM users WHERE data LIKE '%proileId=12345%' I can come up for reasons why each of these might out perform the other, but I'm curious to know the logic.

  • Getting unique items from NSMutableArray

    - by Gidogeek
    Hi Guys, I have a question about Objective-C today involving NSMutableArray. Coming from a .net/c# background I'm having some trouble working with these things. Let's say I have an object called "Song" My song has 3 properties: Title Artist Genre I have a NSMutableArray or NSArray wich holds all my Song objects. How would I go about trying to 'query' my array to get a new array with only (Unique) Artists or Genre's. Where as in .net you would write a simple LINQ query with a DISTINCT clause, how would one solve this in Objective-C ? I'm guessing with predicates but am struggling to find a solution. Thanks in advance.

  • How do I automatically delete an Excel file after creating it on a server and returning it to the us

    - by David A Gibson
    Hello, I am creating an Excel file on a web server, using OleDb to connect the the physical (well as physical as it can be) file and appending records. I am then returning a FilePathResult to the user via MVC, and would like to delete the physical file afterwards due to data protection concerns over the appended records. I have tried using a File.Delete in a Finally clause but I get a File Not Found error which must mean the file has gone when MVC is trying to send the file to the user. I thought about creating the File as a MemoryStream but I think OleDb needs a physical file to connect to so this isn't an option. Any suggestions on how to delete the file after returning it in one operation? Thanks

  • SQL: Is it quicker to insert sorted data into a table?

    - by AngryWhenHungry
    A table in Sybase has a unique varchar(32) column, and a few other columns. It is indexed on this column too. At regular intervals, I need to truncate it, and repopulate it with fresh data from other tables. insert into MyTable select list_of_columns from OtherTable where some_simple_conditions order by MyUniqueId If we are dealing with a few thousand rows, would it help speed up the insert if we have the order by clause for the select? If so, would this gain in time compensate for the extra time needed to order the select query? I could try this out, but currently my data set is small and the results don't say much.

  • JavaScript inheritance extend function

    - by Zach
    I'm having some trouble understanding the IF clause at the end of this function from Pro JavaScript Design Patterns: function extend(subClass, superClass) { var F = function() {}; F.prototype = superClass.prototype; subClass.prototype = new F(); subClass.prototype.constructor = subClass; subClass.superclass = superClass.prototype; if(superClass.prototype.constructor == Object.prototype.constructor) { superClass.prototype.constructor = superClass; } } The book explains that these lines ensure that the superclass's constructor attribute is correctly set, even if the superclass is the Object class itself. Yet, if I omit those three lines and do the following: function SubClass() {}; extend(SubClass, Object); alert(Object.prototype.constructor == Object); The alert says 'true', which means the superclass's constructor is set correctly even without those last three lines. Under what conditions, then, does this IF statement do something useful? Thanks.

  • is right to implement a business logic in the type binding DI framwork?

    - by Martino
    public IRedirect FactoryStrategyRedirect() { if (_PasswordExpired) { return _UpdatePasswordRedirectorFactory.Create(); } else { return _DefaultRedirectorFactory.Create(); } } This strategy factory method can be replaced with type binding and when clause: Bind<IRedirect>.To<UpdatePasswordRedirector>.When(c=> c.kernel.get<SomeContext>().PasswordExpired()) Bind<IRedirect>.To<DefaultRedirector>.When(c=> not c.kernel.get<SomeContext>().PasswordExpired()) I wonder which of the two approaches is the more correct. What are the pros and cons. Especially in the case in which the logic is more complex with more variables to test and more concrete classes to return. is right to implement a business logic in the binding?

  • Table changes depending on dropdown list values with servlet

    - by kawtousse
    What I want to realize is the following: In a JSP x I have a 3 dropdownlists and a button called edit when user click this button a table dynamically should be displayed. Now this table is modified correponding the values in those 3 dropdownlists. So it can be 3 cols or 4 cols or even 6 cols, it depends on the selected values. So what I tried is to use the servlet to getParameter doing the if clause construct the html and then forward the response. Have you any the suggestion of the structure that I can use in JSP? Thank you.

  • From .NET TO SQL

    - by Berlioz
    How do you pass a value from your DAL to your sproc so that the ISNULL function will do it's job. Particularly the DATE value coming from my .NET assembly. In T-SQL an INSERT STMNT and in the VALUES clause, the line of interest goes like this; ISNULL(@myparm_forcolumn9, @myparm_forcolumn9). What value do I pass from .NET to make this line in my sproc work universally, so I don't have to write a millions INSERT SPROCS for every combination of columns??? I just want to write one stored procedure(sproc) that will handle all INSERTS in my universe.

  • How Do I Update a Table From Another Table Only If the Result Count is 1?

    - by Russ Bradberry
    I have a table of 2 tables in a one to many relationship. I want to run an update script that will update the table with the FK of the related table only if there is one result (because if there is multiple then we need to decide which one to use, in another method) Here is what I have so far: UPDATE import_hourly_event_reports i SET i.banner_id = b.banner_id FROM banner b JOIN plan p ON b.plan_id = p.id WHERE b.campain_id = i.campaign_id AND b.size_id = i.size_id AND p.site_id = i.site_id HAVING COUNT(b.banner_id) = 1 As you can see, the HAVING clause doesn't quite work as I'd expect it. I only want to update the row in the import table with the id of the banner from the banner table if the count is equal to 1.

  • Is there a way to split the results of a select query into two equal halfs?

    - by Matthias
    I'd like to have a query returning two ResultSets each of which holding exactly half of all records matching a certain criteria. I tried using TOP 50 PERCENT in conjunction with an Order By but if the number of records in the table is odd, one record will show up in both resultsets. Example: I've got a simple table with TheID (PK) and TheValue fields (varchar(10)) and 5 records. Skip the where clause for now. SELECT TOP 50 PERCENT * FROM TheTable ORDER BY TheID asc results in the selected id's 1,2,3 SELECT TOP 50 PERCENT * FROM TheTable ORDER BY TheID desc results in the selected id's 3,4,5 3 is a dup. In real life of course the queries are fairly complicated with a ton of where clauses and subqueries.

  • Was: Not unique table :: Now: #1054 - Unknown column - can't understand why!?

    - by Andy Barlow
    Hi! I'm trying to join some tables together in MySQL, but I seem to get an error saying: #1066 - Not unique table/alias: 'calendar_jobs' I really want it to select everything from the cal_events, the 2 user bits and just the destination col from the jobs table, but become "null" if there arn't any job. A right join seemed to fit the bill but doesn't work! Can anyone help!? UPDATE: Thanks for the help on the previous query, I'm now up to this: SELECT calendar_events.* , calendar_users.doctorOrNurse, calendar_users.passportName, calendar_jobs.destination FROM `calendar_events` , `calendar_users` RIGHT JOIN calendar_jobs ON calendar_events.jobID = calendar_jobs.jobID WHERE `start` >= 0 AND calendar_users.userID = calendar_events.userID; But am now getting an error saying: #1054 - Unknown column 'calendar_events.jobID' in 'on clause' What is it this time!? Thanks again!

  • Translate SQL to LINQ query - group/join/filter

    - by Paddy
    I have the following query: SELECT S.[FlowOrder], S.[DESCRIPTION], COUNT(I.ID) FROM WorkFlowStatus AS S INNER JOIN Item AS I ON S.ID = I.StatusID WHERE I.Installation = '1' GROUP BY S.[Description], S.[FlowOrder] ORDER BY S.[FlowOrder] Which gives me the count of an item, grouped by a foreign key to workflow, outputting the descriptive name from my FK table. I've go this far with the LINQ query (using LINQ-to-SQL) in the background: var items = from s in _entities.WorkflowStatus join i in _entities.Items on s.ID equals i.StatusId into Statuses orderby s.FlowOrder select new {s.Description, ItemCount = Statuses.Count() }; How do I get the where clause in the SQL into this LINQ query?

  • Rails - Why is my custom validation being triggered for only a build command.

    - by adam
    I have a sentence and correction model with a has_one and belongs_to relationship respectively. For some reason when I do def create @sentence = Sentence.find(params[:sentence_id]) @correction = @sentence.build_correction(params[:correction]) a custom validation I wrote for Correction is being called at the build_correction point. the validation is below class Correction < ActiveRecord::Base attr_accessible :text, :sentence_id, :user_id belongs_to :sentence belongs_to :user validate :correction_is_different_than_sentence def correction_is_different_than_sentence errors.add(:text, "can't be the same as the original sentence.") if (text == self.sentence.text) end the problem is for some reason on validation the correction object doesn't have the sentence id set (despite I used the build_correction method) and so it complains "you have nil object .... while executing nil.text" in the if clause in the validation above. So my question is why is the validation occuring for a build command, i thought it only triggers on a create or update. And why isnt the sentence_id getting set?
