服务器HOST属性和PQ_HOST数据库获取方式
The device table only stores some properties, the rest (including custom server properties) are in primitive_bl_value table. The relationship between the two tables is not obvious from first look; there's probably another table that maps associations, probably for bl_value_id values. Either way, what Bill suggested is much cleaner, easier, and most importantly - supported:

blcli_execute Server getFullyResolvedPropertyValue [server] HOSTblcli_storeenv Hostblcli_execute Server getFullyResolvedPropertyValue [server] FQ_HOSTblcli_storeenv FQ_Host
