Solution 1

The resultset returned by your stored procedure does not specify a column name. When you try to read the subtotal column, you will get an error, because there is no such column in the resultset.

Add a column alias in your stored procedure:

SQL

SELECT sum(subtotal) As subtotal FROM ...

Or access the column by index instead of name:

VB.NET

Me.lblWeeklyRevenue.Text = Convert.ToString(sdr(0))

Thanks Mr.Richard
I used your advice, but result is '1' even though there are data in table.
Pls advice me.
Thank you

That means that the first column of the first row returned by your stored procedure is 1.

Since we can't see your entire procedure, and have no access to your data, we can't tell you why. You'll need to debug the code yourself.
