From Previous Forum Post: Table Adapter Parameterized Query.I added a query. FillByDate using Table Adapter which takes a date as input from the code. The query I have set is the following: [code] lastdate (string object) is a date (inside double quote) provided in the code. The code does not generate error but I get a screen which asks the date as input despite the fact that it has already been provided in the code. [code]

I'm adding queries to a wizard generated Table Adapter with WHERE condition that involes the "%" wildcard:
SELECT * FROM Customers WHERE Country = @Country AND CustomerID LIKE @CustomerID
--If I add % after @CustomerID, I get an error message that the --query can't be parsed but if I run the query as above it returns all --the rolls irrespective the value I supplied for the CustomerID column.Only performance counts!
Using VS-2008, VB and SQL 2005 Developer:
I'm using Queries within the TableAdapter to grab certain data record field validations, most of them are using the Scalar Query to see if a certain condition returns a record or not.
I have one check I need to do that SUMs three fields and have tried it with both a Scalar and Regular Select, both return the results fine, my problem is creating the right syntax in the VB code to check the returned values.
Here's the Query Code in the Adapter (called GetInvoiceSum) and I pass it the cJobNum
SELECT sum(taxable) as taxable, sum(material+labor) AS subtotal, sum(tax) AS tax from ticket where jobnum = @cJobnum Here is the Code in the VB app - it gives me errors on the declaration and I've tried various types DataRow, DataSet, etc....not sure what I'm missing here and am very new at this....
Dim nSumTicket As DataSet = Me.TicketTableAdapter.GetInvoiceSum(cJobnum)
I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....
code to populate combo box:
Public Shared Function LoadCallSource() As String
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"
[code]....
If I take out the line
Me.MemoTableAdapter.Fill(Me.Table_Memo.Tables("Memo"), intMemoID)
The Combo boxes do not act up or "Lock"
I created a new query in the dataset designer. There are now 2 queries there. The original one and the new one.I also added named parameters in the Where clause of the 2nd query.This is the query in the new one:
SELECT ID, FatherName, MotherName, EmergencyContactName,
EmergencyContactRelationship, Address1, Address2, City, State, Zip,
PrimaryPhone, SecondaryPhone, Emaile.

I copy/paste one datagridview from one form to another (different solutions) using two instances of VS 2005.The target form has the datagridview with all settings, including the DataSet and tableAdapter used by the original form. The datagridview also has all old settings. Everything is fine, it works as expected, with one drawback: every time I make any change in the target form surface, VS tells me that the dataset and the tableadapter are not defined and no longer loads the form in design mode giving errors mention that the dataset and the tableadapter are not defined.To be able to view the form surface in Design Mode, I have to edit the form.Designer.vb file and replace the references to the dataset and tableadapter as follows

I have a form that fills a table adapter with this:

To get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?

The code works fine with a smaller database, so i was just wondering the problem is that the database is too big and the adapter isn't able to handle such a long query. I was just wondering if anyone knows what kind of limits there are?
