| View as plain text | |||
Hi all, I have a table of users which contains a lot of information, and also a column called membershiptype which can either be 0, 1, or 2. This table is used a lot in various searches, and all results should be ordered by membership type, but the order should not be 0-1-2, but instead 1-2-0. Currently, this is achieved like this: SELECT ... ORDER BY (membershiptype <> 1) ASC, (membershiptype <> 2) ASC, login ASC ...which is rather ugly, and forces MySQL to create a temp table with the calculated expressions and then re-sort the result using these. Since this query is used a lot, it would be nice if I could get rid of this. I'm completely stumped. Any ideas? No, I did not choose the sort order. No, I can not change the values used. Yes, it has to be this sort order. :-) /Henrik Schröder
