SQL SERVER 查看数据库执行过哪些语句（SQL历史语句记录）

SQL SERVER 查看数据库执行过哪些语句（SQL历史语句记录）

1、查看SQL执行效率和语句

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Select TOP 1000        ST.text AS '执行的SQL语句',        QS.execution_count AS '执行次数',        QS.total_elapsed_time AS '耗时',        QS.total_logical_reads AS '逻辑读取次数',        QS.total_logical_writes AS '逻辑写入次数',        QS.total_physical_reads AS '物理读取次数',              QS.creation_time AS '执行时间' ,         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、其他参考

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

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
