Hi Stuart, Good solution! I didn't even think of that. :-) Interestingly, and FYI, it doesn't work correctly on 4.1.0 (ignores the LIMIT). Hopefully it's a known bug that's been fixed in 4.1.1.
4.1.0 does work correctly though using derived tables as John Bonnett suggested: SELECT * FROM (SELECT * FROM table ORDER BY RAND() LIMIT 20) tbl_alias ORDER BY col1 Matt ----- Original Message ----- From: "Stuart M.
