Attenzione!! Non riesco ad eseguire la query SELECT ac.*, ac.id AS i, c.id, c.nome FROM manofuori_articoli_categoria AS ac, manofuori_categoria AS c WHERE ac.stato="on" AND ac.categoria=c.id AND c.id= AND ac.id!= ORDER BY ac.data_ora DESC LIMIT 10 !!

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND ac.id!= ORDER BY ac.data_ora DESC LIMIT 10' at line 1
