Pbar,The row with the max value for the column identity is the recently inserted * from table_name where identity_col in (sel max(identity_col) from table_name);cheers:-)

Hello,With only having an IDENTITY column and no Insert/Update Date/Timestamp, you cannot get the latest inserted row.Smilever, please note IDENTITY does not generate values in sequence.HTH!Regards,Adeel

The Teradata 12.0 release provides a new feature that enables the auto-generated key value (or all the columnds inserted row) to be returned to the application. The feature is available through the ODBC API. Usage information may be found in the "ODBC Driver for Teradata User Guide" publication.

What particular feature in the ODBC API are you referring to for retrieving the IDENTITY value?
