This topic is not maintained. For the current version, see sys.dm_exec_trigger_stats.

Returns aggregate performance statistics for cached triggers. The view contains one row per trigger, and the lifetime of the row is as long as the trigger remains cached. When a trigger 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.

In Windows 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.

 

Column name Data type Description

database_id

int

Database ID in which the trigger resides.

object_id

int

Object identification number of the trigger.

type

char(2)

Type of the object:

TA = Assembly (CLR) trigger

TR = SQL trigger

Type_desc

nvarchar(60)

Description of the object type:

CLR_TRIGGER

SQL_TRIGGER

sql_handle

varbinary(64)

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

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

Time at which the trigger was added to the cache.

last_execution_time

datetime

Last time at which the trigger was executed.

execution_count

bigint

total_worker_time

bigint

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

last_worker_time

bigint

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

min_worker_time

bigint

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

max_worker_time

bigint

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

total_physical_reads

bigint

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

last_physical_reads

bigint

Number of physical reads performed the last time the trigger was executed.

min_physical_reads

bigint

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

max_physical_reads

bigint

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

total_logical_writes

bigint

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

last_logical_writes

bigint

Number of logical writes performed the last time the trigger was executed.

min_logical_writes

bigint

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

max_logical_writes

bigint

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

total_logical_reads

bigint

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

last_logical_reads

bigint

Number of logical reads performed the last time the trigger was executed.

min_logical_reads

bigint

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

max_logical_reads

bigint

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

total_elapsed_time

bigint

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

last_elapsed_time

bigint

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

min_elapsed_time

bigint

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

max_elapsed_time

bigint

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