Query to find out the sessions trying to create table.

Question

Hi Folks,
I wanted to know the sessions that are trying to create tables. I'm trying to use the query... but not getting the correct results...
These are the three versions of queries i wrote..
SELECT A.SID,A.USERNAME,A.SQL_ID,B.SQL_TEXT FROM V$SESSION A,V$SQLTEXT B
WHERE A.STATUS='ACTIVE'
AND A.SQL_ID=B.SQL_ID
AND B.SQL_TEXT LIKE '%INSERT%' OR B.SQL_TEXT LIKE '%insert%'
SELECT A.SID,A.USERNAME,A.SQL_ID,B.SQL_TEXT FROM V$SESSION A,V$SQLTEXT B
WHERE A.SID IN (SELECT SID FROM V$SESSION WHERE STATUS='ACTIVE')
AND A.SQL_ID=B.SQL_ID
AND B.SQL_TEXT LIKE '%INSERT%' OR B.SQL_TEXT LIKE '%insert%'
select sid, serial#, status, username, osuser,machine,sql_id from v$session
where sql_id in (select sql_id from v$sqltext where SQL_TEXT like '%INSERT%'
union
select sql_id from v$sqltext where SQL_TEXT like '%insert%')
But its not giving me the correct results. Can any one help me with a query to determine a way to catch the sessions trying to create tables.
Thanks

I'm not sure why this needs further explanation. A database is a conceptual and logical whole, it is not a dumpground. Databases are designed prior to their creation, after their creation only the content of the database change, not the database itself.
Having end-users creating tables on the fly means you have no control over the database and also no control over it's integrity and consistency.
Basically this means your database has been converted into a garbage dump.
End-users creating tables on the fly is a big nono in my book, and whoever develops an application creating tables on the fly should be shown to the door of unemployment.
You would either set up audit and issue audit table as explained before, or revoke the create table privilege from all end-users. Personally I prefer the last approach, and I wouldn't even consider the former.
