Thanks everyone for responding promptly. Not sure if I can be authoritative for many, but for me, the need emanates from having to move an ETL off MSSQL Server, which supports OUTPUT $action (similar to RETURNING * in Postgres) where $action is the per-row status (INSERT / UPDATE). My use-case is to create an extra row for all UPDATEd rows (only), which is implemented in MSSQL by enveloping the MERGE with an INSERT (MERGE ... OUTPUT $action) WHERE $action = 'UPDATE'. Am still to test, but looks like Thom's reply earlier could take care of my use-case, so we may need more people requesting this magic field, with a valid use-case. -- Robins Tharakan
