Many tables referencing to one table field?

Intuitively that feels not the right way to do it. I think MySQL would be confused too; how would it validate that a constraint is being met; would it try posts first, or comments first ... maybe both?

You just need to reference your comments table since it already references the posts table, this way whenever you get a report you have the key to the comment and the key to the post.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
