i cant seem to find how to request a user to logon. i tried using a substitution variable for the password but this doesnt work. my substitution variable works fine for the the sales_person_id, but not for the password. i also cant locate this in the textbook. did i miss something?

try the logon command without specifying a username and password. I think.

Try with a username but no password (also no slash)

The way I see this question, is that we must ASK the user to log on as Demo/student.

So all that I did was use an IF statement to check if the user is DEMO/STUDENT and if not, asks then to log in as demo/student.

I hope this is the right way..grinning smiley

In the textbook, page 266 - but i the question don't specify error handling - so i don't think we have to include an exception / error message.

simon, i checked out pg 266. this is prob what the question wanted ja. the question couldve been phrased differently though - my understanding is that the user must be logged into oracle. what is described on pg 266, the oracle user isnt changed. but anyway i submitted my assignment already so i cant change it now.

Probably a bit late now but after hours of trying it different ways I eventually realised my mistake. Every time I would load the .sql file and use 'R' or '/' to run it. This works fine for the PL/SQL code but not for the "CONN user_name" instruction. The answer is as simple as running your program with the @ command. For example @Q7A.SQL. Also the CONNECT command should not be used as part of the PL/SQL code.

I did it as it was set out in the hint given with the question.
