And following statement also fails:

IF NOT EXISTS(SELECT o.name, i.name FROM tempdb..sysobjects o,
tempdb..sysindexes i WHERE o.id = i.id AND o.name='abcattbl' AND
i.name='abcattbl_tnam_ownr') EXECUTE("CREATE INDEX abcattbl_tnam_ownr
ON abcattbl(abt_tnam ASC, abt_ownr ASC)")

"Could not SQLExecute"

Log says "Index already exists"

Thank you.
