karimali831 Posted March 6, 2010 Share Posted March 6, 2010 if userID is in clanID (table cup_clan_members) and clanID is in cupID (table cup_clans) and the same userID is in a different clanID (table cup_clan_members), that clanID can not signup to cupID (table cup_clans) someone tell me a better expression please because according to an expert, it's wrong and I don't see nothing wrong with my table structure. Take a look at attatchments. [attachment deleted by admin] Quote Link to comment Share on other sites More sharing options...
