Please can you explain in detail about the queries which are not executing? SQL queries which execute in Qlikview will not execute in QlikView. I mean these queries work on ODBC or OLE DB connection and they will fetch the data to QlikView. I understand that we write the SQL queries in QlikView but they dont get executed in QV Engine. Also, I am assuming that you are using "SQL" keyword at the beginning of the script?
I hope this helps!
