When a SET QUERY_BAND FOR SESSION request sets, changes, or removes a Proxy User, Vantage also removes all volatile and materialized temporary tables from the session. For materialized global temporary tables, this causes additional locks to be placed on the DBC.TempTables and DBC.TempStatistics system tables.

Vantage does not remove the volatile and materialized temporary tables when you set a Proxy User in a SET QUERY_BAND FOR TRANSACTION request.
