Think of it in SQL*PLUS. If you issue a SELECT ... FOR UPDATE statment, it
opens an implicit cursor returns the rows and closes the cursor. But it
doesn't release the lock.
Locks can only be released by COMMIT/ROLLBACK

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
