Re: Upsert data in one Table based on data in another Table?

Varun,

you may want to use the WITH PRIMARY KEY clause for this use case.

REPLACE | UPSERT - SAP HANA SQL and System Views Reference - SAP Library

Something like

UPSERT T WITH PRIMARY KEY

SELECT U.COL, U.VAL FROM U ;

should work (if your T table does have a PRMARY KEY).
