Oracle查询慢SQL的语句

2024-6-14 我好笨

SELECT v.SQL_TEXT,m.* FROM (select distinct snap_id,

                sql_id,

                EXECUTIONS_DELTA,

                trunc(max(ELAPSED_TIME_DELTA)

                      OVER(PARTITION BY snap_id, sql_id) / 1000000,

                      0) max_elapsed,

                trunc((max(ELAPSED_TIME_DELTA)

                       OVER(PARTITION BY snap_id, sql_id)) /

                      (SUM(ELAPSED_TIME_DELTA) OVER(PARTITION BY snap_id)),

                      2) * 100 per_total

  from dba_hist_sqlstat t WHERE T.snap_id IN (SELECT MAX(snap_id) FROM dba_hist_sqlstat) ) M,v$sql v

  where m.sql_id=v.sql_id and m.max_elapsed>=30

直接上代码

上面代码还是有个问题，SQL过长的时候，SQL展示不全。用下面可以。执行时间超过30秒的，都会被查询出来，你可以改时间。

SELECT v.SQL_FULLTEXT,m.* FROM (select distinct snap_id,

                sql_id,

                EXECUTIONS_DELTA,

                trunc(max(ELAPSED_TIME_DELTA)

                      OVER(PARTITION BY snap_id, sql_id) / 1000000,

                      0) max_elapsed,

                trunc((max(ELAPSED_TIME_DELTA)

                       OVER(PARTITION BY snap_id, sql_id)) /

                      (SUM(ELAPSED_TIME_DELTA) OVER(PARTITION BY snap_id)),

                      2) * 100 per_total

  from dba_hist_sqlstat t WHERE T.snap_id IN (SELECT MAX(snap_id) FROM dba_hist_sqlstat) ) M,v$sqlarea v

  where m.sql_id=v.sql_id and m.max_elapsed>=30
