The script creates a stored procedure which lists all permissions on a given db on execution. Unlike other scripts it does not use a cursor. I have chosen the sp_* prefix as I have created it in master. Have fun!
Frank gives us his take on Codd's Rules. If you're new to databases, this is the core theory that resulted in the development of RDBMS. If you're more experienced with databases, maybe now is a good time to return to the rules to see how you're doing!
