mysql> select dm.model_name,mc.mclass_name,dm.create_time,dm.destroy_time,mt.mtype_name,v.vendor_name,dm.device_type from devicemodel dm, modelclass mc, vendor v, modeltype mt where dm.model_class=mc.model_class and dm.vendor=v.vendor and dm.mtype_h=mt.mtype_h and dm.model_name like '<device_name>';
