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
