If speed is a concern and storage is not, I believe that the fixed length char() will provide a better speed.

If your data will always fit into 255 characters (or less) then use a varchar, if you always know the exact length then use a char. Use the text range of data types if you need more storage space but still want to be able to run fulltext indexes etc. -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
