End users can connect to Teradata Database through middle-tier (non-Teradata) applications using pooled sessions. You can use the SET QUERY_BAND statement to attach metadata to end user SQL queries that cannot otherwise be associated with the session.

Application users with SQL privileges can submit SET QUERY_BAND statements. For users who cannot submit SQL, you can program the application to inject a SET QUERY_BAND statement containing the needed metadata.
