我相信在座各位的回答。

这个脚本展示了如何找到影响SQL的最慢的20个查询

select top 20 dest.text, deqs.execution_count, deqs.total_elapsed_time, deqs.total_worker_time,
(deqs.total_elapsed_time / deqs.execution_count) as 'avg_elapse_time',
(deqs.total_worker_time / deqs.execution_count) as 'avg_worker_time'
from sys.dm_exec_query_stats as deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) as dest
where deqs. last_execution_time >= '2021-09-27 16:00' /* YOUR DATE AND TIME HERE*/
order by 'avg_elapse_time' desc

如果需要，可以通过SQL Profiler监视SQL查询

你可以使用“每次保存自动生成脚本”，如果你使用管理工作室。 这当然不是日志。 检查一下是否对你有用。；）

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

这将显示查询运行的时间和日期

If the queries you are interested in are dynamic queries that fail intermittently, you could log the SQL and the datetime and user in a table at the time the dynamic statement is created. It would be done on a case-by case basis though as it requires specific programming to happen and it takes a littel extra processing time, so do it only for those few queries you are most concerned about. But having a log of the specific statements executed can really help when you are trying to find out why it fails once a month only. Dynamic queries are hard to thoroughly test and sometimes you get one specific input value that just won't work and doing this logging at the time the SQL is created is often the best way to see what specifically wasn in the sql that was built.

如果您需要通过SMSS执行的查询的历史记录。

你可能想试试SSMSPlus。

这个特性在SSMS中并不是现成的。

您需要SSMS 18或更新版本。
