DB/Reporting :: Changing TableAdapter CommandText At Runtime?

Nov 23, 2009

In my app (written in VS 2003) I use OleDbDataAdapter's to load data. I have some functions that enable be to change the OleDbDataAdapter.SelectCommand.CommandText at run time, by adding a "WHERE" or "HAVING" section to the SQL command, or updating the "WHERE " or "HAVING" section. This way I have have generic load data functions. (load all invoices for Customer 123, load all invoices for the year 2009, or load all invoices for Customer 123 for the year 2009).

With the new VS 2008 TableAdapter, the TableAdaper.CommandCollection property is Protected. How can I edit the TableAdaper.CommandCollection(0).CommandText at run time?

Binding DataGridView To TableAdapter Query That Takes Parameters?

Aug 3, 2009

I'm trying to bind a datagridview to a tableadapter which contains a query that requires parameters (for the WHERE statement of the query). The datasource is a SQL Server database. When I bind the datagridview in design view, it does not let me choose which tableadapter method I would like to use. The way I've been fixing this is to go into the code behind that form, where Visual Studio puts in some auto-generated code that fills a datatable in the dataset and I change the method that it's using there and put in my parameters. I don't think this is the proper way to do it, however, especially because sometimes that code doesn't even get generated! My other solution is to just programatically bind the datagridview to a datatable which I have filled using the tableadapter. This seems like more work than it should be, though.

TableAdapter FillBy Query With Parameters Doesn't Work With LIKE Operator

Jan 19, 2010

Banging my head against a wall here. I have a query that looks like this.

SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName LIKE 'JOE%'

That works absolutely fine in query wizard and the DataTablePreview data window. However, when I do this.

SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName LIKE ?

I get nothing when I run the fillby method. If I change the LIKE to =.

SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName = ?

Everything works great. I need to get LIKE working though so I can wildcard search.

I'm using the SQL server OLE db connections if that means anything.

UPDATE

Using the LIKE operator doesn't work at all. When I just swap out = for LIKE. Nothing is returned.

Executing A Sql Command - Number Of Values Provided Must Be Equal To The Number Of Placeholders In Query?

Aug 11, 2010

I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET

Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:

Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})

Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command

DB/Reporting :: Combo Box Filled By Query?

Aug 2, 2010

I'm fairly new to visual basic and have a problem that is probably quite easy to solve yet I have been unable to do it so far and am about at wits end.I have an access database with a table that contains a list of cities and states. what i would like to do is to populate a combo box on a vb form with a list of the states in the states column. the query that i have is as follows:

SELECT DISTINCT State from Cities I have previewed the data in the dataset designer and it works, i just can't figure out how to make it fill the combo box. i initially created a table with just all of the states and then used a binding source and table adapter to bind it to the combo box, but if I'm able to figure this out this would help with my application going forward
