ORACLE如何查看執(zhí)行時(shí)間較長較慢的語句？

運(yùn)行慢的sql：

select * from (select sa.SQL_TEXT， sa.SQL_FULLTEXT， sa.EXECUTIONS "執(zhí)行次數(shù)"， round(sa.ELAPSED_TIME / 1000000， 2) "總執(zhí)行時(shí)間"， round(sa.ELAPSED_TIME / 1000000 / sa.EXECUTIONS， 2) "平均執(zhí)行時(shí)間"， sa.COMMAND_TYPE， sa.PARSING_USER_ID "用戶ID"， u.username "用戶名"， sa.HASH_VALUE from v$sqlarea sa left join all_users u on sa.PARSING_USER_ID = u.user_id where sa.EXECUTIONS > 0 order by (sa.ELAPSED_TIME / sa.EXECUTIONS) desc) where rownum <= 50
