通过top 5等待事件查看sql语句

设计的动态性能视图有：v$session_event,v$session,v$sqlarea，首先在v$session_event中可以找到event，然后通过其动态性能视图找到sid，可以在v$session中找到相应的sql_id,然后再通过sql_id在v$sqlarea中找到sql_text

查看所有的事件的sql语句

select distinct s.sql_id,s.sid,se.event,se.TOTAL_WAITS,sa.sql_text
from v$session s  left join v$session_event se  
on  s.sid=se.sid
left join v$sqlarea sa
on s.sql_id=sa.sql_id
where sa.SQL_TEXT is not null
order by se.total_waits desc;

对单独的event事件的语句的查询

select s.sql_id,se.event,sa.sql_text
from v$session s, v$session_event se,v$sqlarea sa
where s.sid=se.sid and s.sql_id=sa.sql_id
and se.event=&event;

SQL> select s.sql_id,se.event,sa.sql_text
from v$session s, v$session_event se,v$sqlarea sa
where s.sid=se.sid and s.sql_id=sa.sql_id
and se.event=&event;  2    3    4  
Enter value for event: 'db file sequential read' 
old   4: and se.event=&event
new   4: and se.event='db file sequential read'
