Comment puis-je utiliser syndicat y commande par dans mysql ?
select * from _member_facebook
inner join _member_pts
ON _member_facebook._fb_owner=_member_pts._username
where _member_facebook._promote_point = 9
ORDER BY RAND() limit 2
UNION ALL
select * from _member_facebook
inner join _member_pts
ON _member_facebook._fb_owner=_member_pts._username
where _member_facebook._promote_point = 8 limit 3
Donnez-moi une erreur
#1221 - Incorrect usage of UNION and ORDER BY
Quelqu'un peut-il m'aider ?
