Subj:   SET Table and UPI

Hello All,

Just need clarification on SET and Unique Primary Index.

As far as I know

SET - Will not allow duplicate rows

MULTISET - Will allow duplicate rows.


If a table has UPI, there could not be any Duplicate rows at all.

I have a table which has UPI and SET option.

Will Teradata checks for duplicate rows twice( as part of SET and UPI ) while insertion.

Please correct me if I am wrong.


Thanks,
