restrict user's view

hi,
I have a table name stud_info where we stored student's information. This is a sharing screen for Undergraduate department and Post graduate department.

To differential a student type either in Undergraduate or Post graduate is using programme type; 1 is for Undergraduate and 2 for Post graduate ;

Now, i want to restrict example, Undergraduate department to view, select,update,delete only student Undergraduate's data, same to Post graduate department where they only allow to view the Post graduate data.

Can somebody provide me instruction and PL/SQL how to do this. thank you very much Received on Wed Jan 14 2004 - 03:45:59 CST
