locks through PL-SQL

--=_MAILER_ATTACH_BOUNDARY1_2003135164054859484421 Content-Type: text/plain; charset=us-ascii

Hi List,

Little confused about the locks. I wrote a plsql procedure as follows:

---


CREATE OR REPLACE procedure b as


cursor sel_up is select * from emp_info for update; 


begin


For emp_rec in sel_up1 LOOP


dbms_output.put_line('Hi');


End loop;


end;


 ---


I am doing select for update in the cursor and coming out of the procedure without commit/rollback. When I run this procedure from sqlplus, it should acquire the lock on the rows and when procedure ends it should release locks as I am closing the cursor.


But even if the procedure completes, it doesn't release lock. It releases locks only if I terminate the session or manually type rollback or commit on the sqlplus prompt. Can somebody explain this ? 


Regards,


Dilip
