Hi all!
I have a strange behavior with this query:
SELECT c.id_contenido,p.fecha_publicacion,c.titulo_esp,c.activo,c.activo,s.label_esp
as label_sbc,p.orden
,p.tapa_spc,p.tapa_cat,p.tapa_principal,p.id_publicacion,ca.label_esp as
label_cat,sp.label_esp as label_spc
FROM cont_contenido c ,cont_p
10 matches
