oschina-過年動彈抽獎sql

老大的sql很精練。 無 SELECT DISTINCT(u.id) FROM osc_opt_logs l, osc_users u WHERE l.user=u.id AND l.obj_type=100 AND u.role 100 AND DATE(l.create_time) = '2013-2-xx' ORDER BY RAND() LIMIT 2

SELECT DISTINCT(u.id) FROM osc_opt_logs l, osc_users u 
WHERE l.user=u.id AND l.obj_type=100 AND u.role < 100 
AND DATE(l.create_time) = '2013-2-xx' 
ORDER BY RAND() 
LIMIT 2
