MY_AUDIT_TRAIL

MY_AUDIT_TRAIL displays the standard audit trail entries related to the current user. The GaussDB audit information is mainly obtained through the pg_query_audit() function. This view exists in both the PG_CATALOG and SYS schemas. Only users with the AUDITADMIN attribute and the SELECT permission on MY_AUDIT_TRAIL can view audit information. If separation-of-duty is disabled, users with the SYSADMIN attribute can also view audit information. The action_name field of GaussDB is different from that of the A database in terms of the audit actions. The type of the transactionid field is the same as that in the A database. In GaussDB, the sql_text field is the parsed SQL statement, which is not completely the same as the executed SQL statement.
