使用以下語句查找出什麽語句占內存最高，針對占內存高的語句進行優化
SELECT SS.SUM_EXECUTION_COUNT,
T.TEXT,
SS.SUM_TOTAL_ELAPSED_TIME AS ‘總和時間‘,
SS.SUM_TOTAL_WORKER_TIME AS ‘執行耗時‘,
SS.SUM_TOTAL_LOGICAL_READS AS ‘總和邏輯讀數‘,
SS.SUM_TOTAL_LOGICAL_WRITES AS ‘總和邏輯寫‘
FROM (SELECT S.PLAN_HANDLE,
SUM(S.EXECUTION_COUNT)SUM_EXECUTION_COUNT,
SUM(S.TOTAL_ELAPSED_TIME)SUM_TOTAL_ELAPSED_TIME,
