If you are creating a record set in your stored procedure, the record set will be in SqlResult, provided the SQLEXEC returns 1, so you need to makes sure y = 1 in the above statement.

If successful, you can check the @@ROWCOUNT in VFP indirectly with:

RECCOUNT( "SqlResult" )

You can also pass back @@ROWCOUNT via an OUTPUT parameter in your stored procedure:

CREATE SPROC sp_Calculate
@RowCnt integer OUTPUT
AS
SELECT * FROM TableName

@RowCnt = @@ROWCOUNT

RETURN 0

Then your SQLEXEC becomes:

LOCAL lnRowCount

lnRowCount = 0

IF SQLEXEC(1,'sp_calculate ?@lnRowCount') = 1
