ORACLE如何查看执行时间较长较慢的语句 – 数据库 – 前端

运行慢的sql：

select * from (select sa.SQL_TEXT, sa.SQL_FULLTEXT, sa.EXECUTIONS “执行次数”, round(sa.ELAPSED_TIME / 1000000, 2) “总执行时间”, round(sa.ELAPSED_TIME / 1000000 / sa.EXECUTIONS, 2) “平均执行时间”, MAND_TYPE, sa.PARSING_USER_ID “用户ID”, u.username “用户名”, sa.HASH_VALUEfrom v$sqlarea saleft join all_users uon sa.PARSING_USER_ID = u.user_idwhere sa.EXECUTIONS > 0order by (sa.ELAPSED_TIME / sa.EXECUTIONS) desc) where rownum <= 50;
