DataSource Controls :: TableAdapter Using Wrong Query?
Jan 19, 2010
I have a quite baffling problem. I've created a Table adapter with 3 queries. 1. GetMemberData() - Return ALL rows. 2. SearchMembersLastName(@q) - Return specified columns from rows that have a column starting with a specified letter. 3. GetMemberDataById(@id)
- Return all rows matching a specified ID.
The Problem is that SearchMembersLastName(@q) is returning ALL coloumns instead of just the ones I want. Here's the query that's in the Table Adapter:
[Code]....
The problem is that it is acting like:
[Code]....
Here's the code that's calling it:
[Code]....
I just can't figure out why this is happening, any help will be greatly appreciated.

I am creating a TableAdapter using corresponding wizard, with a GetDataByID() query. The select statement is like this:select * from books where ID = ?Thus books are filtered by ID. But in case a null is passed as a parameter, I want to select all records rather than none. Could you please tell me how I can do it?

VS 2008 ASP.NET 3.5 app connecting to an MS SQL 2005 backend. The app contains a strongly typed dataset with a number of TableAdapters. I'm trying to add a query to one of the TableAdapters that deletes from table A, then related entries from table B, then related entries in the master table - table C. The query looks like this:
[Code]....
When I try to run that query to test it out, an error dialog box pops up that says "Unable to parse query text" followed by a second error dialog box that says "Must declare scalar variable @ID". Will the TableAdapters not run sequential Delete statements like this or did I do something wrong?
**Side note: A cascading Delete foriegn key relationship would be ideal, and was configured on the development database, but the DBAs messed up when replicating the database on the production server and getting them to fix something like this can be a difficult process.

There are several articles and blogs that are sort of about this subject but I haven't found one on point. Wondering if anyone has done this? Using VS2008 creating an ASP.NET 3.5 app with a strongly-typed dataset connecting to an MS SQL backend. In one TableAdapter, I have a custom Insert statement that inserts the record into the primary table. There are two other tables the also need records inserted into them and those records contain the record ID from the primary table. Here's an example of what I'm trying to accomplish:

I have this Insert statement working fine: [Code]....
It inserts a new record into a single table. The PK is a field named QID.what the equivalent Update code would be? I'm not sure of the syntax for the Update values (old and new) and Where clause.I'm assuming something beginning with: existingQ.Update

I right click on a TableAdapter, select Add Query, select using QueryBuilder, then select a field to filter upon, and add Filter as =@BookStem. Automatically the QueryBuilder adds the WHERE clause to my new query:HERE (BookStem = '@BookStem')When I press OK, I get "BookStem in expression is not part of the query". And filtering doesn't work.

I have created a function that is called when a user wishes to upload a file to the database. The problem I am having is that it won't write the files to the database anymore. This function used to work before I implemented a treeview (which connects to the database). I am struggling to see how the treeview could have cause the file upload to stop working (the error may not even be related to the implementation of the treeview).
The error message I am receiving is: 'Update' is not a member of 'CMS.SiteFilesDSTableAdapters.SiteFilesTableAdapter'.
The code for the upload function is:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function AddSiteFile(ByVal FileData As Byte(), ByVal FileName As String, ByVal FileDescription As
[code]....
It is throwing the error at: Dim rowsAffected As Integer = Adapter.Update(SiteFiles)
' Return true if precisely one row was inserted, otherwise false
Return rowsAffected = 1
EDIT: I managed to solve this problem by following:
http://www.asp.net/%28S%28pdfrohu0ajmwt445fanvj2r3%29%29/learn/data-access/tutorial-69-cs.aspx
Basically, I had used an Inner Join to gather all the fields, and table adapters don't seem to like them.
INSERT INTO [SiteFiles] ([FileData], [FileName], [FileDescription], [FileType], [FileCreated], [FileCreatedBy]) VALUES (@FileData, @FileName, @FileDescription, @FileType, @FileCreated, @FileCreatedBy)

I'm lost as to where to look next. Here is a sample of what I'm doing:
[Code].... The related tableadapter insert statement was autogenerated by VS2008:
INSERT INTO [ProductCycleCountItem] ([ProductCycleCountLocationID], [ProductID], [CountOnly], [Status]) VALUES (@ProductCycleCountLocationID, @ProductID, @CountOnly, @Status);
SELECT id, ProductCycleCountLocationID, ProductID, CountOnly, Status FROM ProductCycleCountItem WHERE (id = SCOPE_IDENTITY())
With multiple users it's as if it was returning @@IDENTITY instead of SCOPE_IDENTITY(). The table will look like this:
id Location product
1 A 5321
2 A 8273
3 B 2827
4 A 1743
The returned dataset will look like this:
id Location Product
1 A 5321
2 A 8273
3 A 1743
Is it maybe a SQL Server (2005) setting that's incorrect?

Going to start this thread over so that it makes more sense.Anyways, my problem is that when trying to configure my ObjectDataSource in design mode, it only gives me 2 options and never gives me the option for the one I need. The other 2 work fine, but for some reason, this 3rd one will not show up in the list.I have a webpage with pics illustrating how I have it setup and the problem ----------> https://sites.google.com/site/configuringobjectdatasource/And I have another webpage with pics illustrating steps I have taken to fix this problem but still nothing -----> https://sites.google.com/site/configodspart2/what is going on and why it will not show up in my list when I try to configure?

I need to insert two rows into a tableadapter - and then take the identity column from each row and update them into a column on each row.
My problem is that I cannot update a column on a newly inserted row. Stepping through the code seems to indicate that I have updated the column, but when I check the database - the column indicates null.
I have tried calling Update on the TableAdapter, then performing the update on the column, and then calling Update again, but the update still isn't taking.

I have a FileSystem based asp.net 2.0 app that uses Sql Server 2005 Express database.
I have only one dataset for this app with only 4 tables. After i have completed it to a part, a co-worker have added some Classes to it, which are not in same namespace of myBLL classes.
Then i tried added a new table to the dataset. It like all other tables in that dataset uses SQL Statements to access and manage data.
The problem started after i added that new table. I cannot access it from code. I can access all previous TableAdapters but not this new one.

I've got an odd problem and can't figure out what's causing it. We've got 2 different DataSets in the same project and I'm seeing different generated code from the MSDataSetGenerator. Both projects are .NET Framework 4.
In one DataSet, I can open the .Designer.cs file and there's a line like:
[Code]....
This essentially exposes a Transaction property to any partial class I create so I can do with it what I want (by setting it to something).
In the other DataSet no matter what I try to do, this Transaction property never gets generated. I've right-clicked on both DataSets and chose "Run Custom Tool" to get them to regenerate (I've even tried deleting the .Designer.cs file before doing this) and they both get generated the same.
I tried to make sure all the properties of the DataSets were the same. Both are using .NET Framework 4.0 and VS2010.
The file that does not generate the Transaction was from a .NET 1.0 asp.net web site that has continually been upgraded through different .NET versions. Right now it's at 4.0 but I don't know if that would have anything to do with it.

I have a webpage that displays the results of a query on a table. The resulting list is sorted by town:
New York
Hyatt Regency Waldorf Astoria
Paris
Hotel du Louvre Hotel Le Meurice
I've been asked to add to this list another sublist of nearby hotels. The intended result is:
New York
Hyatt Regency Waldorf Astoria nearby hotels:
hotel 1 hotel 2
Paris
Hotel du Louvre Hotel Le Meurice nearby hotels:
hotel 3 hotel 4
I've got a TableAdapter set up in VS2010 so that I can query the table for nearby hotels with "@town" as the parameter. So at the end of each list of hotels in a town, I need to display the results of this query.
If the query turns up no records (no nearby hotels), I don't want to display anything. If it turns up 1 or more records, I want to display the list of nearby hotels.
I am trying to set up a conditional "if" statement that checks to see if any records returned but am getting an error when I try to build:
Error 3 'Maine_Innkeeper_Site_2010.App_Code.DataAccessLayer.MaineInnsDatasetTableAdapters.membersTableAdapter.GetNearbyProperties(string)' is a 'method', which is not valid in the given context E:Ed dataclientsMaine InnkeepersMIA website 2010Maine Innkeeper Site 2010lodging-search-output.aspx.cs 49 49 Maine Innkeeper Site 2010 [Code]....

I spent about 60 minutes sifting through search engine listings trying to figure this out and couldn't find an answer, so I decided to make this post for others.
Situation: Using a Stored Procedure to insert a row and return the new row ID, explained here. In my case, I used the Idenity_Scope to return the new row, like so:
[Code]....
Next, following steps as described in link above, went into the dataset XSD page, configured the table adapter to use this stored procedure. By default, it wanted my return value to be set to some value, but I set to allow Null (makes sense, since I don't want to pass the value in, I want to get it out, so it should be null to begin with).
Problem: Where I ran into an issue was in the method to call this stored procedure. The intellisense displayed the prototype it was expecting, basicly like this:

I fill a GridView from a ObjectDataSource that points to a Typed DataSet.
I need to read a couple of row columns from the object data source that IS NOT part of the Gridview.
So far, I have found out that ObjectDataSource.ObjectDataSource_Selected is the right event to do this.
Examples on the internet refers to e.OutputParameters, but that appears to be empy even though rows are returned.
e.ReturnValue seem to contain a type related to the row type, but I cannot interpret this either.

I have a TableAdapter that consists of an SQL SELECT query.
Need to create an "if" statement that checks to see if the query returned any records.

So, I have 3 table adapters in my dataset, and trying to configure the objectDataSource will not give me the option to select the correct table adapter.
I set up a temporary website to illustrate what I am talking about, along with pics, not much, just 4 pics.
https://sites.google.com/site/configuringobjectdatasource/
The first 2 pics are irrelevant but just in case anyone thinking I don't have it set up properly. The other table adapters are working fine, which I have gridviews being populated etc.
why it will not give me the option to select aspnet_GetRecordDatesTableAdapter?

Sure could use some guidance and clarification here. This is an ASP.NET 3.5 app built with VS2008.The data is provided through a strongly typed dataset and TableAdapters containing Ad Hoc queries. A requirement on the project was recently modified. Previously, this query was used to select records based on a specified ZoneID:
[Code]....
The requirement now is that if no ZoneID is selected, the page passes a value of 0, it ignores the WHERE statement and selects all records. Otherwise, it passes the integer value to ZoneID and selects all records associated with that ZoneID.
I have tried several variations including CASE statements in the WHERE clause and surrounding the entire query. I also tried [Code]....
By including a SET statement in SQL Server Management Studio, this works. However, Ad Hoc queries in TableAdapters do not support DECLARE statements.
This also did not work: [Code]....
And neither did this: [Code]....

I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?
