Purpose
The V$OB_SQL_AUDIT view displays statistics about each SQL request on the current OBServer node, such as the source and execution status of the request. This view is tenant-specific, and only the sys tenant can query this view in other tenants.
Note
This view is introduced since OceanBase Database V4.0.0.
