Is this disguise for your real business problem? I mean, project-
planning tools are plentiful on the market, so I don't see why you
would write your own. Or is it a class assignment?
In any case, for this types of questions, it helps if you post:
o CREATE TABLE statements for your tables.
o INSERT statements with sample data.
o The desired result given the sample.
This helps to clarify ambiguities in your post, and it also makes it
easy to copy and past to develop a tested solution.
.... although, if it's really a class assignment, you are better to
discuss the problem with your teacher. You are likely to learn more
that way.
