SQL Server 2005 查询历史记录 [英] SQL Server 2005 Query History

问题描述

我可以使用以下 SQL 轻松查看最近运行的查询列表:

I can easily see a list of recently run queries using the following SQL:

SELECT      deqs.last_execution_time AS [Time],
            dest.TEXT AS [Query]
FROM        sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
ORDER BY    deqs.last_execution_time DESC

此查询返回 8,500 行 - 今天针对数据库执行的所有查询.

This query returns 8,500 rows - all queries executed against the DB today.

问题:有什么办法可以查看整周针对数据库运行的查询?特定的一天怎么样?

Question: Is there any way to see the queries run against the DB for the entire week? How about for a specific day?

推荐答案

每次重新启动 SQL Server 时，sys.dm_exec_query_stats 中的数据都会重置.因此，如果您只看到一天的数据，那么服务器肯定在很久以前就已重置.

The data in sys.dm_exec_query_stats is reset every time SQL Server is restarted. So if you're only seeing a day's worth of data, the server must have been reset about that long ago.
