Question

I am new to oracle database.

Can someone give me an example of the steps for how to see the last statements executed on the Oracle database 11g r2?

Answer 1

You can use the below query to get the last sql executed based on last sql which was active in database

select ltrim(sq.sql_text)
  from v$sql sq, v$session se, v$open_cursor oc
 where sq.sql_id = oc.sql_id
   and se.saddr = oc.saddr
   and se.sid = oc.sid
   and se.audsid = SYS_CONTEXT('userenv', 'sessionid')
 order by oc.LAST_SQL_ACTIVE_TIME desc;

You can also use the below to find the last query executed in your session.

  SELECT (SELECT t2.sql_fulltext
    FROM   v$sql t2
    WHERE  t1.prev_sql_id = t2.sql_id
           AND t1.prev_child_number = t2.child_number) sql_fulltext
   FROM   v$session t1
   WHERE  t1.audsid = Sys_context('userenv', 'sessionid');
