I learned that there are three types of indexes (PRIMARY, UNIQUE, and INDEX).
Now assuming I create a performance-critical PRIMARY key, will I better have to specify UNIQUE and INDEX for this column also !? It should be obvious that a primary key is unique anyway, and an index as well, shouldnt it !? Please note, I am not after saving disk space here, performance is all I am after, and such a three-fold indexing exercise just seems redundant to me in the best case scenario, or harmful even, am I right there !? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
