sys.dm_exec_procedure_stats (Transact-SQL)

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)

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, the query_cache_removal_statistics event is raised similar to sys.dm_exec_query_stats for SQL Server and Azure SQL Managed Instance.

In Azure SQL Database, dynamic management views cannot expose information that would impact database containment or expose information about other databases the user has access to. To avoid exposing this information, every row that contains data that doesn't belong to the connected tenant is filtered out.

Note

The results of sys.dm_exec_procedure_stats may vary with each execution as the data only reflects finished queries, and not ones still in-flight. To call this from Azure Synapse Analytics or Analytics Platform System (PDW), use the name sys.dm_pdw_nodes_exec_procedure_stats. This syntax is not supported by serverless SQL pool in Azure Synapse Analytics.

Column name Data type Description
database_id int Database ID in which the stored procedure resides.

In Azure SQL Database, the values are unique within a single database or an elastic pool, but not within a logical server.
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.

Will always be 0x000 when a natively compiled stored procedure queries a memory-optimized table.
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 The number of times that the stored procedure has been executed since it was last compiled.
total_worker_time bigint The total amount of CPU time, in microseconds, that was consumed by executions of this stored procedure since it was compiled.

For natively compiled stored procedures, total_worker_time may not be accurate if many executions take less than 1 millisecond.
last_worker_time bigint CPU time, in microseconds, that was consumed the last time the stored procedure was executed. 1
min_worker_time bigint The minimum CPU time, in microseconds, that this stored procedure has ever consumed during a single execution. 1
max_worker_time bigint The maximum CPU time, in microseconds, that this stored procedure has ever consumed during a single execution. 1
total_physical_reads bigint The total number of physical reads performed by executions of this stored procedure since it was compiled.

Will always be 0 querying a memory-optimized table.
last_physical_reads bigint The number of physical reads performed the last time the stored procedure was executed.

Will always be 0 querying a memory-optimized table.
min_physical_reads bigint The minimum number of physical reads that this stored procedure has ever performed during a single execution.

Will always be 0 querying a memory-optimized table.
max_physical_reads bigint The maximum number of physical reads that this stored procedure has ever performed during a single execution.

Will always be 0 querying a memory-optimized table.
total_logical_writes bigint The total number of logical writes performed by executions of this stored procedure since it was compiled.

Will always be 0 querying a memory-optimized table.
last_logical_writes bigint 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.

Will always be 0 querying a memory-optimized table.
min_logical_writes bigint The minimum number of logical writes that this stored procedure has ever performed during a single execution.

Will always be 0 querying a memory-optimized table.
max_logical_writes bigint The maximum number of logical writes that this stored procedure has ever performed during a single execution.

Will always be 0 querying a memory-optimized table.
total_logical_reads bigint The total number of logical reads performed by executions of this stored procedure since it was compiled.

Will always be 0 querying a memory-optimized table.
last_logical_reads bigint The number of logical reads performed the last time the stored procedure was executed.

Will always be 0 querying a memory-optimized table.
min_logical_reads bigint The minimum number of logical reads that this stored procedure has ever performed during a single execution.

Will always be 0 querying a memory-optimized table.
max_logical_reads bigint The maximum number of logical reads that this stored procedure has ever performed during a single execution.

Will always be 0 querying a memory-optimized table.
total_elapsed_time bigint The total elapsed time, in microseconds, for completed executions of this stored procedure.
last_elapsed_time bigint The elapsed time, in microseconds, for the most recently completed execution of this stored procedure.
min_elapsed_time bigint The minimum elapsed time, in microseconds, for any completed execution of this stored procedure.
max_elapsed_time bigint The maximum elapsed time, in microseconds, for any completed execution of this stored procedure.
total_spills bigint The total number of pages spilled by execution of this stored procedure since it was compiled.

Applies to: Starting with SQL Server 2017 (14.x) CU3
last_spills bigint The number of pages spilled the last time the stored procedure was executed.

Applies to: Starting with SQL Server 2017 (14.x) CU3
min_spills bigint The minimum number of pages that this stored procedure has ever spilled during a single execution.

Applies to: Starting with SQL Server 2017 (14.x) CU3
max_spills bigint The maximum number of pages that this stored procedure has ever spilled during a single execution.

Applies to: Starting with SQL Server 2017 (14.x) CU3
pdw_node_id int The identifier for the node that this distribution is on.

Applies to: Azure Synapse Analytics, Analytics Platform System (PDW)
total_page_server_reads bigint The total number of page server reads performed by executions of this stored procedure since it was compiled.

Applies to: Azure SQL Database Hyperscale
last_page_server_reads bigint The number of page server reads performed the last time the stored procedure was executed.

Applies to: Azure SQL Database Hyperscale
min_page_server_reads bigint The minimum number of page server reads that this stored procedure has ever performed during a single execution.

Applies to: Azure SQL Database Hyperscale
max_page_server_reads bigint The maximum number of page server reads that this stored procedure has ever performed during a single execution.

Applies to: Azure SQL Database Hyperscale

1 For natively compiled stored procedures when statistics collection is enabled, worker time is collected in milliseconds. If the query executes in less than a millisecond, the value will be 0.

Permissions

On SQL Server and SQL Managed Instance, requires VIEW SERVER STATE permission.

On SQL Database Basic, S0, and S1 service objectives, and for databases in elastic pools, the server admin account, the Microsoft Entra admin account, or membership in the ##MS_ServerStateReader## server role is required. On all other SQL Database service objectives, either the VIEW DATABASE STATE permission on the database, or membership in the ##MS_ServerStateReader## server role is required.

Permissions for SQL Server 2022 and later

Requires VIEW SERVER PERFORMANCE STATE permission on the server.

Remarks

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

Examples

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;
