[edit] Remark

For the example, what is the point of having BLUE and blue? I think this poses confusion without explanation. JWHPryor 19:26, 13 December 2006 (UTC)JWHPryor

wouldn't all columns together also be a superkey? By the definition given in this article? --Avl 15:49, 20 February 2007 (UTC)

Yes, as long as the table or view you consider does not contain duplicate rows. 151.46.130.95 18:00, 8 March 2007 (UTC)

Aha, so the provided example does not list ALL superkeys? I think perhaps this should be made explicit, as it is written now, one may be given the impression that only the sets of columns listed constitute superkeys, when in fact, there are many more superkeys. --Avl 18:15, 26 March 2007 (UTC)

I changed the example so as to remove the ambiguity. --Nabav 14:13, 16 April 2007 (UTC)
