Note
This view is available starting with V4.0.0.
Purpose
The GV$OB_SQL_AUDIT view displays the source, execution status, and other statistics for each SQL request on all OBServer nodes. This view is tenant-separated, and only the system tenant can query it. Other tenants cannot query it across tenants.
