problema con consulta

[richarparrao]

Código SQL:

SELECT a.id, a.username, a.email, b.update_id, b.UPDATE, b.TIME, b.user_id_fk FROM usuarios a INNER JOIN updates b ON (a.id = b.user_id_fk) INNER JOIN  relationships  c ON (c.user_from = $user_id AND  c.user_to =  b.user_id_fk ) WHERE  c.STATUS = '1'
 

no lo he probado....
