  • multiple keys and values with google-collections

    - by flash3000
    Hello, I would like use google-collection in order to save the following file in a Hash with multiple keys and values Key1_1, Key2_1, Key3_1, data1_1, 0, 0 Key1_2, Key2_2, Key3_2, data1_2, 0, 0 Key1_3, Key2_3, Key3_3, data1_3, 0, 0 Key1_4, Key2_4, Key3_4, data1_4, 0, 0 The first three columns are the different keys and the last two integer are the two different values. I have already prepare a code which spilt the lines in chunks. import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; public class HashMapKey { public static void main(String[] args) throws FileNotFoundException, IOException { String inputFile = "inputData.txt"; BufferedReader br = new BufferedReader(new FileReader(inputFile)); String strLine; while ((strLine = br.readLine()) != null) { String[] line = strLine.replaceAll(" ", "").trim().split(","); for (int i = 0; i < line.length; i++) { System.out.print("[" + line[i] + "]"); } System.out.println(); } } } Unfortunately, I do not know how to save these information in google-collection? Thank you in advance. Best regards,

  • Why can't Doctrine retrieve my model data?

    - by scottm
    So, I'm trying to use Doctrine to retrieve some data. I have some basic code like this: $conn = Doctrine_Manager::connection(CONNECTION_STRING); $site = Doctrine_Core::getTable('Site')->find('00024'); echo $site->SiteName; However, this keeps throwing a SQL error that 'column siteid does not exist'. When I look at the exception the SQL query is this (you can see the error is that the inner_tbl alias for siteid is set to s__siteid, so querying inner_tabl.siteid is what's broken): SELECT TOP 1 [inner_tbl].[siteid] AS [s__siteid] FROM (SELECT TOP 1 [s].[siteid] AS [s__siteid], [s].[name] AS [s__name], [s].[address] AS [s__address], [s].[city] AS [s__city], [s].[zip] AS [s__zip], [s].[state] AS [s__state], [s].[region] AS [s__region], [s].[callprocessor] AS [s__callprocessor], [s].[active] AS [s__active], [s].[dateadded] AS [s__dateadded] FROM [Sites] [s] WHERE ([s].[siteid] = '00024') ) AS [inner_tbl] Why is the query being generated this way? Could it be the way the Yaml schema is laid out? Site: connection: 0 tableName: Sites columns: siteid: type: string(5) fixed: true unsigned: false primary: true autoincrement: false name: type: string(300) fixed: false unsigned: false notnull: true primary: false autoincrement: false address: type: string(100) fixed: false unsigned: false notnull: false primary: false autoincrement: false city: type: string(100) fixed: false unsigned: false notnull: false primary: false autoincrement: false zip: type: string(5) fixed: false unsigned: false notnull: false primary: false autoincrement: false state: type: string(2) fixed: true unsigned: false notnull: true primary: false autoincrement: false region: type: integer(4) fixed: false unsigned: false notnull: true default: (5) primary: false autoincrement: false callprocessor: type: integer(4) fixed: false unsigned: false notnull: true primary: false autoincrement: false active: type: integer(1) fixed: false unsigned: false notnull: true primary: false autoincrement: false dateadded: type: timestamp(16) fixed: false unsigned: false notnull: true default: (getdate()) primary: false autoincrement: false

  • How can I filter a JTable?

    - by Jonas
    I would like to filter a JTable, but I don't understand how I can do it. I have read How to Use Tables - Sorting and Filtering and I have tried with the code below, but with that filter, no rows at all is shown in my table. And I don't understand what column it is filtered on. private void myFilter() { RowFilter<MyModel, Object> rf = null; try { rf = RowFilter.regexFilter(filterFld.getText(), 0); } catch (java.util.regex.PatternSyntaxException e) { return; } sorter.setRowFilter(rf); } MyModel has three columns, the first two are strings and the last column is of type Integer. How can I apply the filter above, consider the text in filterFld.getText() and only filter the rows where the text is matched on the second column? I would like to show all rows that starts with the text specified by filterFld.getText(). I.e. if the text is APP then the JTable should contain the rows where the second column starts with APPLE, APPLICATION but not the rows where the second column is CAR, ORANGE. I have also tried with this filter: RowFilter<MyModel, Integer> itemFilter = new RowFilter<MyModel, Integer>(){ public boolean include(Entry<? extends MyModel, ? extends Integer> entry){ MyModel model = entry.getModel(); MyItem item = model.getRecord(entry.getIdentifier()); if (item.getSecondColumn().startsWith("APP")) { return true; } else { return false; } } }; How can I write a filter that is filtering the JTable on the second column, specified by my textfield?

  • Class; Struct; Enum confusion, what is better?

    - by Angel Brighteyes
    I have 46 rows of information, 2 columns each row ("Code Number", "Description"). These codes are returned to the client dependent upon the success or failure of their initial submission request. I do not want to use a database file (csv, sqlite, etc) for the storage/access. The closest type that I can think of for how I want these codes to be shown to the client is the exception class. Correct me if I'm wrong, but from what I can tell enums do not allow strings, though this sort of structure seemed the better option initially based on how it works (e.g. 100 = "missing name in request"). Thinking about it, creating a class might be the best modus operandi. However I would appreciate more experienced advice or direction and input from those who might have been in a similar situation. Currently this is what I have: class ReturnCode { private int _code; private string _message; public ReturnCode(int code) { Code = code; } public int Code { get { return _code; } set { _code = value; _message = RetrieveMessage(value); } } public string Message { get { return _message; } } private string RetrieveMessage(int value) { string message; switch (value) { case 100: message = "Request completed successfuly"; break; case 201: message = "Missing name in request."; break; default: message = "Unexpected failure, please email for support"; break; } return message; } }

  • Sqlite3 "chained" query

    - by Arrieta
    I need to create a configuration file from a data file that looks as follows: MAN1_TIME '01-JAN-2010 00:00:00.0000 UTC' MAN1_RX 123.45 MAN1_RY 123.45 MAN1_RZ 123.45 MAN1_NEXT 'MAN2' MAN2_TIME '01-MAR-2010 00:00:00.0000 UTC' MAN2_RX 123.45 [...] MAN2_NEXT 'MANX' [...] MANX_TIME [...] This file describes different "legs" of a trajectory. In this case, MAN1 is chained to MAN2, and MAN2 to MANX. In the original file, the chains are not as obvious (i.e., they are non-sequential). I've managed to read the file and store in an Sqlite3 database (I'm using the Python interface). The table is stored with three columns: Id, Par, and Val; for instance, Id='MAN1', Par='RX', and Val='123.45'. I'm interested in querying such database for obtaining the information related to 'n' legs. In English, that would be: "Select RX,RY,RZ for the next five legs starting on MAN1" So the query would go to MAN1, retrieve RX, RY, RZ, then read the parameter NEXT and go to that Id, retrieve RX, RY, RZ; read the parameter NEXT; go to that one ... like this five times. How can I pass such query with "dynamic parameters"? Thank you.

  • Should the entity framework + self tracking entities be saving me time

    - by sipwiz
    I've been using the entity framework in combination with the self tracking entity code generation templates for my latest silverlight to WCF application. It's the first time I've used the entity framework in a real project and my hope was that I would save myself a lot of time and effort by being able to automatically update the whole data access layer of my project when my database schema changed. Happily I've found that to be the case, updating my database schema by adding a new table, changing column names, adding new columns etc. etc. can be propagated to my business object classes by using the update from database option on the entity framework model. Where I'm hurting is the CRUD operations within my WCF service in response to actions on my Silverlight client. I use the same self tracking entity framework business objects in my Silverlight app but I find I'm continually having to fight against problems such as foreign key associations not being handled correctly when updating an object or the change tracker getting confused about the state of an object at the Silverlight end and the data access operation within the WCF layer throwing a wobbly. It's got to a point where I have now spent more time dealing with this quirks than I have on my previous project where I used Linq-to-SQL as the starting point for rolling my own business objects. Is it just me being hopeless or is the self tracking entities approach something that should be avoided until it's more mature?

  • What is the correct date format for a Date column in YUI DataTable ?

    - by giulio
    I have produced a data table. All the columns are sortable. It has a date in one column which I formatted dd/mm/yyyy hh:mm:ss . This is different from the default format as defined in the doco, but I should be able to define my own format for non-american formats. (See below) The DataTable class provides a set of built-in static functions to format certain well-known types of data. In your Column definition, if you set a Column's formatter to YAHOO.widget.DataTable.formatDate, that function will render data of type Date with the default syntax of "MM/DD/YYYY". If you would like to bypass a built-in formatter in favor of your own, you can point a Column's formatter to a custom function that you define. The table is generated from HTML Markup, so the data is held within "" tags. This gives me some more clues about compatible string dates for javascript: In general, the RecordSet expects to hold data in native JavaScript types. For instance, a date is expected to be a JavaScript Date instance, not a string like "4/26/2005" in order to sort properly. Converting data types as data comes into your RecordSet is enabled through the parser property in the fields array of your DataSource's responseSchema I suspect that the I'm missing something in the date format. So what is an acceptable string date for javascript, that Yui dataTable will recognise, given that I want format it as "dd/mm/yyyy hh:mm:ss" ?

  • Magento resource model for table with compound primary key

    - by sdek
    I am creating a custom module for a Magento ecommerce site, and the module will center around a new (ie, custom) table that has a compound/composite primary key, or rather the table has two columns that make up the primary key. Does anybody know how to create your models/resource models based on a table with a compound key? To give a few more details, I have looked up several tutorials and also used the excellent moduleCreator script. But it seems like all the tutorials revolve around the table having a PK with just one column in it. Something like this: class <Namespace>_<Module>_Model_Mysql4_<Module> extends Mage_Core_Model_Mysql4_Abstract { public function _construct(){ $this->_init('<module_alias>/<table_alias>', '<table_primary_key_id>'); } } Also, I just noticed that looking at the database model almost all tables have a single primary key. I understand this has much to do with the EAV-style db structure, but still is it possible to use a table with a compound PK? I want to stick with the Magento framework/conventions if possible. Is it discouraged? Should I just change the structure of my custom table to have some dummy id column? I do have the ability to do that, but geez! (Another side note that I thought I would mention is that it looks like the Zend Framework provides a way to base a class on a table with compound primary key (see Example #20 on this page - about half-way down), so it seems that the Magento framework should also provide for it... I just don't see how.)

  • How to get NSFormatter subclass to work with NSTableColumn sort key and selector?

    - by Andrew
    My setup: I have a sqlite database from which I populate a NSMutableArray of NSDictionary objects this is the DataSource for my NSTableView. One of the columns holds "time", the time is a float that holds seconds. I would like to display the values in this column as minutes:seconds. For instance my data would be 123.4329387 I want to display 2:03 which I have no problem doing with a subclass of NSFormatter (or NSNumberFormatter) applied to my NSTextField in the column. I have sorting set up by using the Table Column Attributes in IB, I just have the sort key set to "time" and the selector set to "compare:" which works fine without the formatter. Currently this gives me something like this when I sort (descending) 1:37, 1:31, 0:10, 0:10, 0:09, 1:30, 1:30, 1:26, 0:09 and similar nonsense, it looks like something is going on but it's definitely not sorted. How do I get the sort to look at the underlying data instead of the formatted value? Alternately, how do I specify a custom sort method and where do I put the code for said method? I have searched around quite a bit and have not found anything to help me out with this problem, any help with this is most appreciated.

  • LINQ-To-SQL and Mapping Table Deletions

    - by Jake
    I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tblFriendsFoods.Where(x => x.Friend.Name == 'Tom' && x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

  • How do I cast <T> to varbinary and be still be able to perform a CONVERT on the sql side? Implicatio

    - by Biff MaGriff
    Hello, I'm writing this application that will allow a user to define custom quizzes and then allow another user to respond to the questions. Each question of the quiz has a corresponding datatype. All the responses to all the questions are stored vertically in my [Response] table. I currently use 2 fields to store the response. //Response schema ResponseID int QuizPersonID int QuestionID int ChoiceID int //maps to Choice table, used for drop down lists ChoiceValue varbinary(MAX) //used to store a user entered value I'm using .net 3.5 C# SQL Server 2008. I'm thinking that I would want to store different datatypes in the same field and then in my SQL report proc I would CONVERT to the proper datatype. I'm thinking this is ideal because I only have to check one field. I'm also thinking it might be more trouble than it is worth. I think my other options are to; store the data as strings in the db (yuck), or to have a column for each datatype I might use. So what I would like to know is, how would I format my datatypes in C# so that they can be converted properly in SQL? What is the performance hit for converting in SQL? Should I just make a whole wack of columns for each datatype?

  • Entity framework entity class mapping with plain .net class

    - by Elan
    I have following in entity framework Table - Country Fields List item Country_ID Dialing_Code ISO_Alpha2 ISO_Alpha3 ISO_Full I would like to map only selected fields from this entity model to my domain class. My domain model class is public class DomainCountry { public int Country_ID { get; set; } public string Dialing_Code { get; set; } public string ISO_3166_1_Alpha_2 { get; set; } } The following will work however insert or update is not possible. In order to get insert or update we need to use ObjectSet< but it will not support in my case. IQueryable<DomainCountry> countries = context.Countries.Select( c => new DomainCountry { Country_ID = c.Country_Id, Dialing_Code = c.Dialing_Code, ISO_3166_1_Alpha_2 = c.ISO_3166_1_Alpha_2 }); It will be really fantastic could someone provide a nice solution for this. Ideally it will be kind of proxy class which will support all the futures however highly customizable i.e. only the columns we want to expose to the outer world

  • Dojo DataGrid, programmatic creation

    - by djna
    I'm trying to create a DataGrid dynamically. Declarative creation is working fine: A source of data: <span dojoType="dojo.data.ItemFileReadStore" jsId="theStore" url="dataonly001.json"> </span> a simple layout: <script type="text/javascript" > var layout = [ { field: 'custId', name: 'Id', } // more items elided ... ]; </script> The grid: <body class="tundra" id="mainbody"> <div id="grid" dojoType="dojox.grid.DataGrid" store="theStore" structure="layout" autoWidth="true" ></div> </body> And I get the grid displayed nicely. Instead, I want to create the grid dynamically. For the sake of figuring out what's broken I've tried to use exactly the same layout and store, removing just teh grid declaration and adding this script: <script type="text/javascript" djConfig="parseOnLoad: true, debugAtAllCosts: true"> dojo.addOnLoad(function(){ // initialise and lay out home page console.log("Have a store:" + theStore); console.log("Have a structure:" + layout); var grid = new dojox.grid.DataGrid({ id:"grid", store : theStore, clientSort : "true", structure : layout }); grid.startup(); dojo.place(grid.domNode, dojo.body(), "first"); }); </script> The effect that I get is a completely empty rectangle is displayed. Using FireBug I can see that the DataGrid widget is created but that it has no rows or columns. So my guess is that the datastore or layout are not being passed correctly. However, it does appear that at the point of creation the values of theStore and layout are correct. Suggestions please, or indeed a working example of a programmic grid might solve the problem.

  • Create a HTML table from nested maps (and vectors)

    - by Kenny164
    I'm trying to create a table (a work schedule) I have coded previously using python, I think it would be a nice introduction to the Clojure language for me. I have very little experience in Clojure (or lisp in that matter) and I've done my rounds in google and a good bit of trial and error but can't seem to get my head around this style of coding. Here is my sample data (will be coming from an sqlite database in the future): (def smpl2 (ref {"Salaried" [{"John Doe" ["12:00-20:00" nil nil nil "11:00-19:00"]} {"Mary Jane" [nil "12:00-20:00" nil nil nil "11:00-19:00"]}] "Shift Manager" [{"Peter Simpson" ["12:00-20:00" nil nil nil "11:00-19:00"]} {"Joe Jones" [nil "12:00-20:00" nil nil nil "11:00-19:00"]}] "Other" [{"Super Man" ["07:00-16:00" "07:00-16:00" "07:00-16:00" "07:00-16:00" "07:00-16:00"]}]})) I was trying to step through this originally using for then moving onto doseq and finally domap (which seems more successful) and dumping the contents into a html table (my original python program outputed this from a sqlite database into an excel spreadsheet using COM). Here is my attempt (the create-table fn): (defn html-doc [title & body] (html (doctype "xhtml/transitional") [:html [:head [:title title]] [:body body]])) (defn create-table [] [:h1 "Schedule"] [:hr] [:table (:style "border: 0; width: 90%") [:th "Name"][:th "Mon"][:th "Tue"][:th "Wed"] [:th "Thur"][:th "Fri"][:th "Sat"][:th "Sun"] [:tr (domap [ct @smpl2] [:tr [:td (key ct)] (domap [cl (val ct)] (domap [c cl] [:tr [:td (key c)]]))]) ]]) (defroutes tstr (GET "/" ((html-doc "Sample" create-table))) (ANY "*" 404)) That outputs the table with the sections (salaried, manager, etc) and the names in the sections, I just feel like I'm abusing the domap by nesting it too many times as I'll probably need to add more domaps just to get the shift times in their proper columns and the code is getting a 'dirty' feel to it. I apologize in advance if I'm not including enough information, I don't normally ask for help on coding, also this is my 1st SO question :). If you know any better approaches to do this or even tips or tricks I should know as a newbie, they are definitely welcome. Thanks.

  • Synchronizing a collection of wrapped objects with a collection of unwrapped objects

    - by Kenneth Cochran
    I have two classes: Employee and EmployeeGridViewAdapter. Employee is composed of several complex types. EmployeeGridViewAdapter wraps a single Employee and exposes its members as a flattened set of system types so a DataGridView can handle displaying, editing, etc. I'm using VS's builtin support for turning a POCO into a data source, which I then attach to a BindingSource object. When I attach the DataGridView to the BindingSource it creates the expected columns and at runtime I can perform the expected CRUD operations. All is good so far. The problem is the collection of adapters and the collection of employees aren't being synchronized. So all the employees I create an runtime never get persisted. Here's a snippet of the code that generates the collection of EmployeeGridViewAdapter's: var employeeCollection = new List<EmployeeGridViewAdapter>(); foreach (var employee in this.employees) { employeeCollection.Add(new EmployeeGridViewAdapter(employee)); } this.view.Employees = employeeCollection; Pretty straight forward but I can't figure out how to synchronize changes back to the original collection. I imagine edits are already handled because both collections reference the same objects but creating new employees and deleting employees aren't happening so I can't be sure.

  • Preparing a MySQL INSERT/UPDATE statement with DEFAULT values

    - by Raveren
    Quoting MySQL INSERT manual - same goes for UPDATE: Use the keyword DEFAULT to set a column explicitly to its default value. This makes it easier to write INSERT statements that assign values to all but a few columns, because it enables you to avoid writing an incomplete VALUES list that does not include a value for each column in the table. Otherwise, you would have to write out the list of column names corresponding to each value in the VALUES list. So in short if I write INSERT INTO table1 (column1,column2) values ('value1',DEFAULT); A new row with column2 set as its default value - whatever it may be - is inserted. However if I prepare and execute a statement in PHP: $statement = $pdoObject-> prepare("INSERT INTO table1 (column1,column2) values (?,?)"); $statement->execute(array('value1','DEFAULT')); The new row will contain 'DEFAULT' as its text value - if the column is able to store text values. Now I have written an abstraction layer to PDO (I needed it) and to get around this issue am considering to introduce a const DEFAULT_VALUE = "randomstring"; So I could execute statements like this: $statement->execute(array('value1',mysql::DEFAULT_VALUE)); And then in method that does the binding I'd go through values that are sent to be bound and if some are equal to self::DEFAULT_VALUE, act accordingly. I'm pretty sure there's a better way to do this. Has someone else encountered similar situations?

  • R + Bioconductor : combining probesets in an ExpressionSet

    - by Mike Dewar
    Hi, First off, this may be the wrong Forum for this question, as it's pretty darn R+Bioconductor specific. Here's what I have: library('GEOquery') GDS = getGEO('GDS785') cd4T = GDS2eSet(GDS) cd4T <- cd4T[!fData(cd4T)$symbol == "",] Now cd4T is an ExpressionSet object which wraps a big matrix with 19794 rows (probesets) and 15 columns (samples). The final line gets rid of all probesets that do not have corresponding gene symbols. Now the trouble is that most genes in this set are assigned to more than one probeset. You can see this by doing gene_symbols = factor(fData(cd4T)$Gene.symbol) length(gene_symbols)-length(levels(gene_symbols)) [1] 6897 So only 6897 of my 19794 probesets have unique probeset - gene mappings. I'd like to somehow combine the expression levels of each probeset associated with each gene. I don't care much about the actual probe id for each probe. I'd like very much to end up with an ExpressionSet containing the merged information as all of my downstream analysis is designed to work with this class. I think I can write some code that will do this by hand, and make a new expression set from scratch. However, I'm assuming this can't be a new problem and that code exists to do it, using a statistically sound method to combine the gene expression levels. I'm guessing there's a proper name for this also but my googles aren't showing up much of use. Can anyone help?

  • Help with MySQL query - Product orders report without duplicate shipping charges

    - by Paul
    Hello, I have an issue creating a custom report for an e-commerce store running on osCommerce. The client wants the report to have the following columns: Date, Order ID, Product Class, Product Price, Product Tax, Shipping, Order Total The criteria for generating the report are Date Range and Product Class (Textbooks for example) The client wants the report to list each Textbook purchased on its own line. Orders with multiple textbooks would display a separate line for each Textbook in the order. I have it all working except for one part: the shipping amount is order-specific (based on the order total), not product-specific, and is displaying for each product. I need it to display only for the first product of each order, so it is not counted more than once. My current query is: SELECT op.date_funds_captured as 'Date', op.orders_id as 'Order ID', pc.class as 'Product Class', round(op.products_price,2) as 'Product Price', round(op.products_tax*op.products_price/100,2) as 'Product Tax', round(otship.value,2) as 'Shipping', round(ot.value,2) as 'Order Total' from orders_products op, orders_total ot, orders_total otship, productclasses pc, products p where ot.orders_id = op.orders_id and ot.class='ot_total' and op.orders_id = otship.orders_id and otship.class = 'ot_shipping' and p.products_class_id = pc.id and op.products_id = p.products_id and pc.id = 1 pc.id = 1 -- Product class = Textbook Here is an example of the current report output. You can see the problem with order 2256 showing the shipping value three times instead of once: Date Order Product Class Price Tax Shipping Total 2010-01-04 2253 Textbook 24.95 2.43 10.03 37.41 2010-01-04 2256 Textbook 34.95 0.00 18.09 240.37 2010-01-04 2256 Textbook 55.50 0.00 18.09 240.37 2010-01-04 2256 Textbook 36.95 0.00 18.09 240.37 2010-01-04 2258 Textbook 55.50 5.41 12.17 124.24 Please help!!!

  • How to change type of information for a Title column in SharePoint MOSS 2007 List?

    - by Ruba
    I created a calendar in SharePoint MOSS 2007 that is connected to my Outlook. I added a custom column “Person” to this list and the type of information in this column is: Person or Group. In SharePoint I can hide Title column and in Calendar View show this Person field as Month View Title. So I can see on the calendar who is working that day. Problem is in Outlook. It seems like Outlook doesn’t know a thing about custom fields. In Outlook I can see only Title and few other fields. I could rename Title field to Person, but I can’t change type of information that it contains. By default it is text field and no way to change it to Person or Group. If I could change those “default” column types, then I think my problem would be solved. I know it is possible. I created a custom list, but this list has also those “sticky” Title, Created By and Modified By columns that can’t be changed or removed. Maybe I have to create a custom list with some other program or code? Please help! Thanks in advance!

  • "select * from table" vs "select colA,colB,etc from table" interesting behaviour in SqlServer2005

    - by kristof
    Apology for a lengthy post but I needed to post some code to illustrate the problem. Inspired by the question What is the reason not to use select * ? posted a few minutes ago, I decided to point out some observations of the select * behaviour that I noticed some time ago. So let's the code speak for itself: IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[starTest]') AND type in (N'U')) DROP TABLE [dbo].[starTest] CREATE TABLE [dbo].[starTest]( [id] [int] IDENTITY(1,1) NOT NULL, [A] [varchar](50) NULL, [B] [varchar](50) NULL, [C] [varchar](50) NULL ) ON [PRIMARY] GO insert into dbo.starTest(a,b,c) select 'a1','b1','c1' union all select 'a2','b2','c2' union all select 'a3','b3','c3' go IF EXISTS (SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[vStartest]')) DROP VIEW [dbo].[vStartest] go create view dbo.vStartest as select * from dbo.starTest go go IF EXISTS (SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[vExplicittest]')) DROP VIEW [dbo].[vExplicittest] go create view dbo.[vExplicittest] as select a,b,c from dbo.starTest go select a,b,c from dbo.vStartest select a,b,c from dbo.vExplicitTest IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[starTest]') AND type in (N'U')) DROP TABLE [dbo].[starTest] CREATE TABLE [dbo].[starTest]( [id] [int] IDENTITY(1,1) NOT NULL, [A] [varchar](50) NULL, [B] [varchar](50) NULL, [D] [varchar](50) NULL, [C] [varchar](50) NULL ) ON [PRIMARY] GO insert into dbo.starTest(a,b,d,c) select 'a1','b1','d1','c1' union all select 'a2','b2','d2','c2' union all select 'a3','b3','d3','c3' select a,b,c from dbo.vExplicittest select a,b,c from dbo.vStartest If you execute the following query and look at the results of last 2 select statements, the results that you will see will be as follows: select a,b,c from dbo.vExplicittest a1 b1 c1 a2 b2 c2 a3 b3 c3 select a,b,c from dbo.vStartest a1 b1 d1 a2 b2 d2 a3 b3 d3 As you can see in the results of select a,b,c from dbo.vStartest the data of column c has been replaced with the data from colum d. I believe that is related to the way the views are compiled, my understanding is that the columns are mapped by column indexes (1,2,3,4) as apposed to names. I though I would post it as a warning for people using select * in their sql and experiencing unexpected behaviour. Note: If you rebuild the view that uses select * each time after you modify the table it will work as expected

  • Strange error when filling a data adapter.

    - by Tim C
    I am receiving the following error in my code (c#, .Net 3.5, VS2008) when I try to connect to an Excel sheet and fill a OleDbDataAdapter with the results of a query. First the error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. And here is the code, which is honestly pretty simple: var excelFileName = string.Format("c:/Metadata_Tool.xlsm"); var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; Extended Properties=Excel 12.0;HDR=YES;", excelFileName); var adapter = new OleDbDataAdapter("Select * FROM [Video Tagging XML]", connectionString); var ds = new DataSet(); adapter.Fill(ds, "VTX"); DataTable data = ds.Tables["VTX"]; foreach (DataRow myRow in data.Rows) { foreach (DataColumn myColumn in data.Columns) { Console.Write("\t{0}", myRow[myColumn]); } Console.WriteLine(); } Console.ReadLine(); I get the error on the line adapter.Fill(ds,"VTX");. I did find a microsoft forum post saying to turn on JIT optimization in VS2008 from the Tools/Options/Debug/General menu, but this did not seem to help. Any help would be greatly appreciated thanks!

  • How to create a column containing a string of stars to inidcate levels of a factor in a data frame i

    - by PaulHurleyuk
    (second question today - must be a bad day) I have a dataframe with various columns, inculding a concentration column (numeric), a flag highlighting invalid results (boolean) and a description of the problem (character) dput(df) structure(list(x = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), rawconc = c(77.4, 52.6, 86.5, 44.5, 167, 16.2, 59.3, 123, 1.95, 181), reason = structure(c(NA, NA, 2L, NA, NA, NA, 2L, 1L, NA, NA), .Label = c("Fails Acceptance Criteria", "Poor Injection"), class = "factor"), flag = c("False", "False", "True", "False", "False", "False", "True", "True", "False", "False" )), .Names = c("x", "rawconc", "reason", "flag"), row.names = c(NA, -10L), class = "data.frame") I can create a column with the numeric level of the reason column df$level<-as.numeric(df$reason) df x rawconc reason flag level 1 1 77.40 <NA> False NA 2 2 52.60 <NA> False NA 3 3 86.50 Poor Injection True 2 4 4 44.50 <NA> False NA 5 5 167.00 <NA> False NA 6 6 16.20 <NA> False NA 7 7 59.30 Poor Injection True 2 8 8 123.00 Fails Acceptance Criteria True 1 9 9 1.95 <NA> False NA 10 10 181.00 <NA> False NA and here's what I want to do to create a column with 'level' many stars, but it fails df$stars<-paste(rep("*",df$level)sep="",collapse="") Error: unexpected symbol in "df$stars<-paste(rep("*",df$level)sep" df$stars<-paste(rep("*",df$level),sep="",collapse="") Error in rep("*", df$level) : invalid 'times' argument rep("*",df$level) Error in rep("*", df$level) : invalid 'times' argument df$stars<-paste(rep("*",pmax(df$level,0,na.rm=TRUE)),sep="",collapse="") Error in rep("*", pmax(df$level, 0, na.rm = TRUE)) : invalid 'times' argument It seems that rep needs to be fed one value at a time. I feel that this should be possible (and my gut says 'use lapply' but my apply fu is v. poor) ANy one want to try ?

  • Dynamic Linq Property Converting to Sql

    - by Matthew Hood
    I am trying to understand dynamic linq and expression trees. Very basically trying to do an equals supplying the column and value as strings. Here is what I have so far private IQueryable<tblTest> filterTest(string column, string value) { TestDataContext db = new TestDataContext(); // The IQueryable data to query. IQueryable<tblTest> queryableData = db.tblTests.AsQueryable(); // Compose the expression tree that represents the parameter to the predicate. ParameterExpression pe = Expression.Parameter(typeof(tblTest), "item"); Expression left = Expression.Property(pe, column); Expression right = Expression.Constant(value); Expression e1 = Expression.Equal(left, right); MethodCallExpression whereCallExpression = Expression.Call( typeof(Queryable), "Where", new Type[] { queryableData.ElementType }, queryableData.Expression, Expression.Lambda<Func<tblTest, bool>>(e1, new ParameterExpression[] { pe })); // Create an executable query from the expression tree. IQueryable<tblTest> results = queryableData.Provider.CreateQuery<tblTest>(whereCallExpression); return results; } That works fine for columns in the DB. But fails for properties in my code eg public partial class tblTest { public string name_test { get { return name; } } } Giving an error cannot be that it cannot be converted into SQL. I have tried rewriting the property as a Expression<Func but with no luck, how can I convert simple properties so they can be used with linq in this dynamic way? Many Thanks

  • Dynamic Column that contains a Repeater

    - by djbyter
    How would I go about doing this programatically? I can do this just fine declaratively, using a template column and then using something like this: ... <TemplateGridColumn> <ItemTemplate> <div> <asp:Image ID="groupImg" CssClass="groupImg" runat="server"/> <asp:Repeater ID="groupItemRpt" runat="server"> <HeaderTemplate> <ul class="groupItemList"> </HeaderTemplate> <ItemTemplate> <li> <asp:Image ID="itemImg" runat="server" /> <asp:HiddenField ID="itemValue" runat="server" /> </li> </ItemTemplate> <FooterTemplate> </ul> </FooterTemplate> </asp:Repeater> </div> </ItemTemplate> </TemplateGridColumn> ... I am dynamically creating this grid based on the data, so I'm already added columns with one set of controls. But now I need to figure out how to show multiple images, which expand/contract if the groupImg image control is clicked (i just toggle the ul) .. Can anyone point me in the right direction? Thanks.

  • Wordpress "Vote It Up" plugin help

    - by Sparks Memphis
    I'm creating a dig like site with wordpress, TDO Mini forms and Vote it up where people who live in the city can log on, post their ideas of how to improve the city and have others vote. on the home page there are 2 columns. right is the TDO submit form. left are the "Most Wanted" items. the posts with the highest rating. I've found an impressive lack of information on this plugin. im not great with php but i can make do most of the time. I want to output the post title, post author, links for yes and no votes as well as have the titles in the left column list in most popular order. preferably id like the home pages to have only the top 5 or so highest rated posts. I cant find any way to output that information as i need. I was really hoping there was a simple way to call the highest rated post titles in the loop for the main page but there doesnt seem to be a way. Bout the only thing i've found is the DisplayVotes tag which isnt incredibly helpful. does anybody know how i can accomplish this, or can provide some expert advise? help would be immensely appreciated.
