将 SQL STATISTICS TIME 和 IO 捕获到表中
有没有办法在 T-SQL 中捕获 STATISTICS IO
和 TIME
以登录到表中?
Is there a way to capture STATISTICS IO
and TIME
within T-SQL, for logging into a table?
推荐答案
排序.
查询统计 DMV 捕获与 SET STATISTICS TIME
给出的统计相同的统计:sys.dm_exec_query_stats
.
The same statistics as those given by SET STATISTICS TIME
are captured by the Query Statistics DMV: sys.dm_exec_query_stats
.
DMV 可以从 T-SQL 中查询,就像普通视图一样.
DMVs can be queried from T-SQL, just like normal views.
然而,SET STATISTICS IO
仅作为每次执行的聚合值 (last_logical_reads, last_physical_read) 捕获,没有 SET STATISTICS IO
给出的每个行集的差异化.
However, the SET STATISTICS IO
are only captured as aggregate values (last_logical_reads, last_physical_read) per execution, without the differentiation per-rowset given by SET STATISTICS IO
.
总体而言,DMV 的作用与 SET STATISTICS IO
相同.
Overall though, the DMVs can serve the same purpose as SET STATISTICS IO
.
