sys.sp_xtp_control_query_exec_stats (Transact-SQL)

  • Článek

Applies to: SQL Server

Enables per query statistics collection for all natively compiled stored procedures for the instance, or specific natively compiled stored procedures.

Performance decreases when you enable statistics collection. If you only need to troubleshoot one, or a few natively compiled stored procedures, you can enable statistics collection for just those few natively compiled stored procedures.

To enable statistics collection at the procedure level for all natively compiled stored procedures, see sys.sp_xtp_control_proc_exec_stats.

Syntax

sys.sp_xtp_control_query_exec_stats
    [ [ @new_collection_value = ] collection_value ]
    [ , [ @database_id = ] database_id ]
    [ , [ @xtp_object_id = ] procedure_id ]
    , [ @old_collection_value = ] old_collection_value OUTPUT
[ ; ]

Arguments

[ @new_collection_value = ] collection_value

Determines whether procedure-level statistics collection is on (1) or off (0). @new_collection_value is bit.

@new_collection_value is set to 0 when SQL Server starts.

[ @database_id = ] database_id, [ @xtp_object_id = ] procedure_id

The database ID and object ID (data type int) for the natively compiled stored procedure. If statistics collection is enabled for the instance (sys.sp_xtp_control_proc_exec_stats), statistics on a natively compiled stored procedure are collected. Turning off statistics collection on the instance doesn't turn off statistics collection for individual natively compiled stored procedures.

Use sys.databases, sys.procedures, DB_ID, or OBJECT_ID to get IDs for a database and stored procedure.

[ @old_collection_value = ] old_collection_value OUTPUT

Returns the current status. @old_collection_value is bit.

Return code values

0 for success. Nonzero for failure.

Permissions

Requires membership in the fixed sysadmin role.

Examples

The following code sample shows how to enable statistics collection for all natively compiled stored procedures for the instance, and then for a specific natively compiled stored procedure.

DECLARE @c BIT;

EXEC sys.sp_xtp_control_query_exec_stats @new_collection_value = 1;

EXEC sys.sp_xtp_control_query_exec_stats @old_collection_value = @c OUTPUT;

SELECT @c AS 'collection status';

EXEC sys.sp_xtp_control_query_exec_stats @new_collection_value = 1,
    @database_id = 5,
    @xtp_object_id = 41576255;

EXEC sys.sp_xtp_control_query_exec_stats @database_id = 5,
    @xtp_object_id = 41576255,
    @old_collection_value = @c OUTPUT;

SELECT @c AS 'collection status';
