First of all, I would suggest to use the table names, and not aliases "a", "b" and "c", to make the statement more readable.

Also, when posting messages on the UT, if you the UT to respect your spaces, use PRE tags (put < pre > at the beginning of your code, and < /pre > at the end - omit the spaces).

HTH,
