HI All,
I want to perform date load from table A to table B. Its failing with unique
constraitn problem.
Could someone post me to find out the rows that are already existing in
TABLE B (target table) (which are in table A i.e. source table).
(better than a union all)
(tables are big they have more than 1 million rows)
Tx and Regards,
Srinivas
