How can I see the last SQL statement executed in Oracle database 11g r2?

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;

Answer 2

Find all sql where sql is like ....

select h.sample_time
, u.username
, h.machine
, s.sql_text
, h.*
from dba_hist_active_sess_history h
inner join v$sql s
on s.sql_id = h.sql_id
left outer join dba_users u
on u.user_id = h.user_id
where s.sql_text like 'DELETE%'
order by h.sample_time desc;

You need to be connected as sysdba user for this sql

Answer 3

You can use the below query:

SELECT program_id, program_line#, sql_text
FROM V$SQL VS , ALL_USERS AU
WHERE (executions >= 1)
AND (parsing_user_id != 0)
AND (AU.user_id(+) = VS.parsing_user_id)
AND UPPER(AU.USERNAME)  IN (UPPER('YourUser'))
ORDER BY last_active_time DESC;

if you need to know the statements of an PL/SQL object were executed then use or join with

select *
    from   dba_objects
    where object_id = program_id

Answer 4

A couple of hints:

• In SQLplus, type a semicolon+ to see, and slash to execute again
• In SQLdeveloper, use F8
• If you mean see other users' statements then it's not possible by default.
  • You can configure AUDIT.
  • You can see some SQL statements in SELECT * FROM V$SQLAREA;

Answer 5

Connect as SYS user and execute the following query

select sql_text from v$sql where first_load_time=(select max(first_load_time) from v$sql) ;
