有的時候，需要知道SQLSERVER執行了什么語句，可以用下面的方法：
SELECT TOP 1000
--創建時間
QS.creation_time,
--查詢語句
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,
--執行文本
ST.text,
--執行計划
QS.total_worker_time,
QS.last_worker_time,
QS.max_worker_time,
QS.min_worker_time
FROM
sys.dm_exec_query_stats QS
--關鍵字
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
--創建時間
QS.creation_time,
--執行文本
ST.text
FROM
sys.dm_exec_query_stats QS
--關鍵字
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
