If you try to INTERSECT on a column of two different tables that has duplicates, you will see only unique records that exists in both tables. INTERSECT Will not display duplicates. ~ IM. @Ken,

Iam currently using a cursor to do the same. Can we go for OLE DB Command flow in SSIS? will it have advantage over cursor. Could you please clarify this? Hi Pinal,
