Need help

Basically, I am coding a community kidn of website. But where you have profiles and you can rate eadh otheres profiles etc. But i only want to be able to rate someones profile once then you cant rate that same person again. How would I go about doing this in sql?

The general idea is that you are going to need to have a table in your DB that tracks who has rated each profile. Then when someone clicks on the link to rate a profile you will need to check that table to see if that person has already rated that the user.

easy.

Save the id of the person who has rated into a table, then and if statement to check all the id's against the current one.
