Recently I was supporting a third party application. It queries to determine what tables it has permissions to before it proceeds with the rest of its functionality. We had implemented permissions based on the best practice of creating roles, assigning the permissions to the roles, and then making the users members of the roles. The application was querying INFORMATION_SCHEMA.TABLE_PRIVILEGES and of course didn't find any permissions directly against the user in question. We ended up granting explicit permissions to the user so the application would work, but I'm more interested in the general case. How can I determine permissions for an individual user?
