Note
This view is available starting with V4.2.2.
Overview
The DBA_WR_SQLSTAT view displays basic performance statistics for SQL statements executed by the current tenant. Each SQL statement is represented as a row (i.e., each unique combination of SQL_ID and Plan_Hash corresponds to one row). A column containing _DELTA indicates that the value represents the increment in statistics from the time the last WR snapshot was collected until the current time.
