Software: Visual Studio & SQl Server 2005.

I have recently ran into a problem where the dataset will not read the table data.
The data is definitely in the table that I need to access.

Thanks for your help!

So many unanswered questions...

1. What does your code look like that attempts to access your data?
2. What does the query or stored procedure look like?
3. Is there an error or exception thrown when trying to access the data?
4. Did this work at one point and suddenly stop working or has it never worked?

There are so many ways to take this, but the bottom line here is that experts cannot connect to your data sources and applications look at code, and run queries to test.   All we have to go on is the text, screenshots, and images you post in questions.

There is a command object used by the TableAdapter. That command object will have a CommandText property. That property will reveal the SQL statement used. There may also be Parameters involved. If you run the same SQL statement with the same parameters directly in SSMS what are the results?

We need more information to go on. Providing the query, its parameters, and the query results would be helpful. Of course, redacting sensitive data in the result set would be appropriate. Also, providing the code surrounding the single line you provided above would help. There should be a connection object, a command object, a DataAdapter, and a DataSet or DataTable object involved.

No error message leads one to think it is working correctly.  How do you test there is data in the table.

I looked in the table with SSMS and the data is there.

Just because the data is in the table doesn't necessarily mean that the command object has the proper query and parameters to retrieve the data. If you run the actual query in SSMS does it return rows?

This may be getting beyond my capabilities...

If you run the actual query in SSMS does it return rows? (How is this done)?

I'm assuming you already know how to connect to the database since you can see the tables.

Once connected, click the "New Query" button in the toolbar at the top to open a query window.

Set a breakpoint in your VB application so you can inspect the command object. Use the debugging environment to extract the CommandText property. Copy this and paste it into SSMS.

Click the "Execute" button in the SSMS toolbar and watch for query results.

>>I looked in the table with SSMS and the data is there.

that isn't what I asked.  I asked how do you check the data is in the table you have in your app - not in the database.
