SQL生成AWR中的SQL ordered by Elapsed Time

 --提取&beg_snap 、&end_snap
 select * from dba_hist_snapshot x ;

--提取&dbid
select * from v$database;

--提取$inst_num
 select * from v$instance; 

執行的時候輸入上面的值(如果需要輸入多次，那麼輸入同樣值即可)

 select *
 from (select round(nvl((sqt.elap / 1000000), to_number(null)),2) "Elapsed Time (s)",
 round( nvl((sqt.cput / 1000000), to_number(null)),2) "CPU Time (s)",
 sqt.exec,  round(decode(sqt.exec, 0, to_number(null),
 (sqt.elap / sqt.exec / 1000000)),2) "Elap per Exec (s)",
