I have a stored procedure that produces a resultset from a query. If the resultset is empty it tries a second query. This results in two result sets, the first being empty. In ASP.NET the data reader sees no data, even though the second result set is populated.
Please help me either, to only return one result set (cancelling the empty one) or how to code ASP.NET (Visual Basic) to read the second result set.

Natloz, My query is contained within a variable and I am running it using a nested EXEC statement.
I tried using your suggestion already but got into difficulties with the syntax:
IF (EXEC('SELECT COUNT(*) FROM ('+@SQLTEXT+') A')=0)
gives
Error 156: Incorrect syntax near the keyword 'EXEC',
Line 81: Incorrect syntax near '='
You can move through the resultsets returned by your sproc using the SqlDataReader.NextResult()
