Max of sum query

Question

I\'m trying to write a query that will list student(s) enrolled with the maximum total credit points.

Here is my query:

    SELECT s.S_ID,
       s.S_LAS

Naughty double posting of the same question! This is the answer I gave to your other posting, same thing still applies here.

I'm pretty sure (no Oracle machine to test this) that your alias is the problem:

sum(q1.CREDITS) Total Credits

Should be

sum(q1.CREDITS) "Total Credits"

And therefore

max( q3.Total Credits)

Should be

max( q3."Total Credits")

Or you could get rid of the space in the alias. But there may be more to it than that, as I say, I've no Oracle machine handy to test that out.
