--某時間內，最耗時SQL
select TOP 100 SUBSTRING(Textdata,1,660) as '名稱',
count(*) as '數量', sum(duration/1000) as '總執行時間ms',
       avg(duration/1000) as '平均執行時間ms',
       avg(cpu) as '平均CPU時間ms',
       avg(reads) as '平均讀次數',
       avg(writes) as '平均寫次數'
from ZGSJY group by substring(Textdata,1,660) 
order by sum(duration) desc
