I have an SQL Stored Procedure and it was working fine until I recently added a new field into the dataset which is returned, now Qlikview fails to load the data and gives no specific error message, just
OLEDB read failed
SQL EXEC dbo.GetTMSessionAnalysisQV
If I amend my SQL to exclude the new field it works fine again. The SQL Stored Procedure executes fine outside of Qlikview as I've tested it.
Does Qlikview expect the stored procedure to return the same schema or something? Where might I be going wrong?
