問題描述
有沒有辦法在 T-SQL 中捕獲 STATISTICS IO 和 TIME 以登錄到表中?
Is there a way to capture STATISTICS IO and TIME within T-SQL, for logging into a table?
推薦答案
排序.
查詢統(tǒng)計(jì) DMV 捕獲與 SET STATISTICS TIME 給出的統(tǒng)計(jì)相同的統(tǒng)計(jì):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 可以從 T-SQL 中查詢，就像普通視圖一樣.
DMVs can be queried from T-SQL, just like normal views.
然而，SET STATISTICS IO 僅作為每次執(zhí)行的聚合值 (last_logical_reads, last_physical_read) 捕獲，沒有 SET STATISTICS IO 給出的每個(gè)行集的差異化.
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.
總體而言，DMV 的作用與 SET STATISTICS IO 相同.
Overall though, the DMVs can serve the same purpose as SET STATISTICS IO.
