SQL SERVER 查看數據庫執行過哪些語句（SQL歷史語句記錄）

SQL SERVER 查看數據庫執行過哪些語句（SQL歷史語句記錄）

1、查看SQL執行效率和語句

Select TOP 1000 
       ST.text AS '執行的SQL語句',
       QS.execution_count AS '執行次數',
       QS.total_elapsed_time AS '耗時',
       QS.total_logical_reads AS '邏輯讀取次數',
       QS.total_logical_writes AS '邏輯寫入次數',
       QS.total_physical_reads AS '物理讀取次數',       
       QS.creation_time AS '執行時間' ,  
       QS.*
FROM   sys.dm_exec_query_stats QS
       CROSS APPLY 
sys.dm_exec_sql_text(QS.sql_handle) ST
Where  QS.creation_time BETWEEN '2020-07-01 00:00:00' AND '2020-09-02 11:00:00' 
orDER BY
     QS.total_elapsed_time DESC 

2、其他參考

SELECT TOP 50
 (total_logical_reads + total_logical_writes) AS total_logical_io,
 (total_logical_reads / execution_count) AS avg_logical_reads,
 (total_logical_writes / execution_count) AS avg_logical_writes,
 (total_physical_reads / execution_count) AS avg_phys_reads,
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,
*
FROM sys.dm_exec_query_stats AS qs
 CROSS APPLY sys.dm_exec_sql_text (qs.sql_handle) AS st
ORDER BY total_logical_io DESC
