Depends what you mean by help. Improve performance of the query, not at all, but that wasn't the original question. In a previous post he said he'd added indexes which his EXPLAIN output clearly shows is not the case. That is simply an example of how to add a PRIMARY KEY after creating the table. However, it will stop duplicate entries from being entered and prepare the way for when he's NOT selecting all rows, so is not entirely wasted. > Also there's no way a database is going to use an index if there are > only 4 rows in the table. True, but if it was only ever going to have 4 entries in it I doubt he'd be using a Db at all. I'm assuming this is just a sample. -- Niel Archer -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
