SQLSERVER 内存占用高的处理方式

方法一： 

方法二：

使用以下语句查找出什么语句占内存最高，针对占内存高的语句进行优化
SELECT SS.SUM_EXECUTION_COUNT,
T.TEXT,
SS.SUM_TOTAL_ELAPSED_TIME AS ‘总和时间‘,
SS.SUM_TOTAL_WORKER_TIME AS ‘执行耗时‘,
SS.SUM_TOTAL_LOGICAL_READS AS ‘总和逻辑读数‘,
SS.SUM_TOTAL_LOGICAL_WRITES AS ‘总和逻辑写‘
FROM (SELECT S.PLAN_HANDLE,
SUM(S.EXECUTION_COUNT)SUM_EXECUTION_COUNT,
SUM(S.TOTAL_ELAPSED_TIME)SUM_TOTAL_ELAPSED_TIME,
SUM(S.TOTAL_WORKER_TIME)SUM_TOTAL_WORKER_TIME,
SUM(S.TOTAL_LOGICAL_READS)SUM_TOTAL_LOGICAL_READS,
SUM(S.TOTAL_LOGICAL_WRITES)SUM_TOTAL_LOGICAL_WRITES
FROM SYS.DM_EXEC_QUERY_STATS S
GROUP BY S.PLAN_HANDLE
) AS SS
CROSS APPLY SYS.dm_exec_sql_text(SS.PLAN_HANDLE)T
ORDER BY SUM_TOTAL_LOGICAL_READS DESC
