With the Auto Generated Key Retrieval (AGKR) feature, a client application can retrieve an identity column value, or a whole row, from the Teradata Database. To use the AGKR feature, include one of the following embedded SQL statements before using an INSERT statement.
To switch off the AGKR feature (this is the default):
EXEC SQL SET RETURNGENERATEDKEYS OFF
To return only the identity column value syntax:
EXEC SQL SET RETURNGENERATEDKEYS COLUMN
To return the entire row:
EXEC SQL SET RETURNGENERATEDKEYS ROW
Note: Teradata Database does not support the use of the AGKR feature with UPSERT and MERGE‑INTO.
