有的时候，需要知道SQLSERVER执行了什么语句，可以用下面的方法：
SELECT TOP 1000
--创建时间
QS.creation_time,
--查询语句
SUBSTRING(ST.text,(QS.statement_start_offset/2)+1,
((CASE QS.statement_end_offset WHEN -1 THEN DATALENGTH(st.text)
ELSE QS.statement_end_offset END - QS.statement_start_offset)/2) + 1
) AS statement_text,
--执行文本
ST.text,
--执行计划
QS.total_worker_time,
QS.last_worker_time,
QS.max_worker_time,
QS.min_worker_time
FROM
sys.dm_exec_query_stats QS
--关键字
CROSS APPLY
sys.dm_exec_sql_text(QS.sql_handle) ST
WHERE
QS.creation_time BETWEEN '2012-12-03 09:00:00' AND '2012-12-03 11:00:00'
--AND ST.text LIKE '%%'
ORDER BY
QS.creation_time DESC
SELECT TOP 1000
--创建时间
QS.creation_time,
--执行文本
ST.text
FROM
sys.dm_exec_query_stats QS
--关键字
CROSS APPLY
sys.dm_exec_sql_text(QS.sql_handle) ST
WHERE
QS.creation_time BETWEEN '2012-12-03 09:00:00' AND '2012-12-03 11:00:00'
AND ST.text NOT LIKE '%SELECT * FROM T_LOCATIONINFO WHERE STRCLIPLOGICID in(%'
ORDER BY
QS.creation_time DESC
