Note
This view is introduced since OceanBase Database V4.2.2.
Purpose
The oceanbase.DBA_WR_SQLSTAT view displays the basic performance statistics of SQL statements executed in the current tenant. Each row indicates one SQL statement. To be specific, each row is uniquely identified by SQL_ID and Plan_Hash. A column whose name contains _DELTA indicates the incremental value since a Workload Repository (WR) snapshot was last collected.
