If I have a table with a primary key like this: CREATE TABLE `answers` ( `qid` INT UNSIGNED NOT NULL , `userid` INT UNSIGNED NOT NULL , `groupid` INT UNSIGNED NOT NULL , `comments` TEXT NOT NULL , PRIMARY ( `qid` , `userid` , `groupid` ) );
But I will also be searching in various pages, for all 'answers' from a certain userid or say that belong to a certain groupid, do I still need to create separate INDEXes for those fields, or is it enough to have them in that combination PRIMARY key? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
