Betty_S Posted February 13, 2007 Share Posted February 13, 2007 Hi How can define a combination of rows as unique? I'm using mysql and need to prevent duplicate row inserting. I don't want to define one column as unique but a combination of 3 columns. How can I do that? thanks Quote Link to comment https://forums.phpfreaks.com/topic/38271-how-can-define-a-combination-of-rows-as-unique/ Share on other sites More sharing options...
