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?

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');

To identify repeatable SQL statements the optimizer will log the identity of each SQL statement into a statement log, the first time it is compiled. After a SQL statement's identity has been logged, if it is processed again (i.e. executed or compiled) the presence of its identity in the statement log will signify it to be a repeatable statement.

  • please elaborate
  • @g00dy - I did have a chuckle at this one. :)
  • I had something like that in mind when I saw it actually: SELECT distinct /*AvoidMe*/first_value(sql_text) OVER(ORDER BY FIRST_LOAD_TIME desc) FROM v$sql where sql_text not like '%AvoidMe%'
