sys.dm_exec_procedure_stats (Transact-SQL)

Returns aggregate performance statistics for cached stored procedures. The view returns one row for each cached stored procedure plan, and the lifetime of the row is as long as the stored procedure remains cached. When a stored procedure is removed from the cache, the corresponding row is eliminated from this view. At that time, a Performance Statistics SQL trace event is raised similar to sys.dm_exec_query_stats.

Note Note

An initial query of sys.dm_exec_procedure_stats might produce inaccurate results if there is a workload currently executing on the server. More accurate results may be determined by rerunning the query.

Column name

Data type

Description

database_id

int

Database ID in which the stored procedure resides.

object_id

int

Object identification number of the stored procedure.

type

char(2)

Type of the object:

P = SQL stored procedure

PC = Assembly (CLR) stored procedure

X = Extended stored procedure

type_desc

nvarchar(60)

Description of the object type:

SQL_STORED_PROCEDURE

CLR_STORED_PROCEDURE

EXTENDED_STORED_PROCEDURE

sql_handle

varbinary(64)

This can be used to correlate with queries in sys.dm_exec_query_stats that were executed from within this stored procedure.

plan_handle

varbinary(64)

Identifier for the in-memory plan. This identifier is transient and remains constant only while the plan remains in the cache. This value may be used with the sys.dm_exec_cached_plans dynamic management view.

cached_time

datetime

Time at which the stored procedure was added to the cache.

last_execution_time

datetime

Last time at which the stored procedure was executed.

execution_count

bigint

Number of times that the stored procedure has been executed since it was last compiled.

total_worker_time

bigint

Total amount of CPU time, in microseconds, that was consumed by executions of this stored procedure since it was compiled.

last_worker_time

bigint

CPU time, in microseconds, that was consumed the last time the stored procedure was executed.

min_worker_time

bigint

Minimum CPU time, in microseconds, that this stored procedure has ever consumed during a single execution.

max_worker_time

bigint

Maximum CPU time, in microseconds, that this stored procedure has ever consumed during a single execution.

total_physical_reads

bigint

Total number of physical reads performed by executions of this stored procedure since it was compiled.

last_physical_reads

bigint

Number of physical reads performed the last time the stored procedure was executed.

min_physical_reads

bigint

Minimum number of physical reads that this stored procedure has ever performed during a single execution.

max_physical_reads

bigint

Maximum number of physical reads that this stored procedure has ever performed during a single execution.

total_logical_writes

bigint

Total number of logical writes performed by executions of this stored procedure since it was compiled.

last_logical_writes

bigint

Number of the number of buffer pool pages dirtied the last time the plan was executed. If a page is already dirty (modified) no writes are counted.

min_logical_writes

bigint

Minimum number of logical writes that this stored procedure has ever performed during a single execution.

max_logical_writes

bigint

Maximum number of logical writes that this stored procedure has ever performed during a single execution.

total_logical_reads

bigint

Total number of logical reads performed by executions of this stored procedure since it was compiled.

last_logical_reads

bigint

Number of logical reads performed the last time the stored procedure was executed.

min_logical_reads

bigint

Minimum number of logical reads that this stored procedure has ever performed during a single execution.

max_logical_reads

bigint

Maximum number of logical reads that this stored procedure has ever performed during a single execution.

total_elapsed_time

bigint

Total elapsed time, in microseconds, for completed executions of this stored procedure.

last_elapsed_time

bigint

Elapsed time, in microseconds, for the most recently completed execution of this stored procedure.

min_elapsed_time

bigint

Minimum elapsed time, in microseconds, for any completed execution of this stored procedure.

max_elapsed_time

bigint

Maximum elapsed time, in microseconds, for any completed execution of this stored procedure.

Requires VIEW SERVER STATE permission on server.

Statistics in the view are updated when a stored procedure execution completes.

The following example returns information about the top ten stored procedures identified by average elapsed time.

SELECT TOP 10 d.object_id, d.database_id, OBJECT_NAME(object_id, database_id) 'proc name', 
d.cached_time, d.last_execution_time, d.total_elapsed_time, d.total_elapsed_time/d.execution_count AS [avg_elapsed_time],
d.last_elapsed_time, d.execution_count
FROM sys.dm_exec_procedure_stats AS d
ORDER BY [total_worker_time] DESC;
