There are various ways to break up your strings and convert part to a number using MySQL SQL, depending on what assumptions we're allowed to make about the format of your strings and the size of your numbers. Jay Blanchard has posted one possibility. However, your sorting will be much faster (and can use indexes better) if you don't have to do such calculations for each row every time you want to sort. If you need to sort by a two-part key, then you really should split the key into two columns, make one VARCHAR and one SMALLINT (or whatever), and make an index on both. -- Keith C.
