GV$OB_SQLSTAT

Last Updated：2024-04-19 08:42:49 Updated

Note

This view is introduced since OceanBase Database V4.2.2.

Purpose

The GV$OB_SQLSTAT view displays the basic performance statistics of SQL statements in the cluster. Each row indicates one SQL statement. To be specific, a 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.

Columns

Column	Type	Nullable?	Description
SVR_IP	varchar(46)	NO	The IP address of the OBServer node.
SVR_PORT	bigint(20)	NO	The port number of the OBServer node.

PLAN_ID	bigint(20)	NO	The ID of the execution plan.
PLAN_HASH	bigint(20) unsigned	NO	The hash value of the execution plan.
PLAN_TYPE	bigint(20)	NO	For SQL plan caching, this column indicates the type of the plan. Valid values: `1`: indicates a local plan. `2`: indicates a remote plan. `3`: indicates a distributed plan. For PL object caching, this column indicates the type of the PL object. Valid values: `1`: indicates a procedure. `2`: indicates a function. `3`: indicates a package. `4`: indicates an anonymous block.
