1、查看SQL执行效率和语句

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

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
