select * from dbo.sysobjects
where id = object_id(N'dbo.ShopsStockReport') and OBJECTPROPERTY(id, N'IsUserTable') = 1
高手帮我解释一下上面语句的意思,尤其是object_id(N'dbo.ShopsStockReport') 和OBJECTPROPERTY(id, N'IsUserTable') = 1,谢谢了
where id = object_id(N'dbo.ShopsStockReport') and OBJECTPROPERTY(id, N'IsUserTable') = 1

object_id(N'dbo.ShopsStockReport')
是取得这个外键的ID号，每个元素在数据库中都有唯一的ID号
OBJECTPROPERTY(id, N'IsUserTable') = 1
判断ID是否是外键
select * from dbo.sysobjects
where id = object_id(N'dbo.ShopsStockReport') and OBJECTPROPERTY(id, N'IsUserTable') = 1
这条语句的意思是取表ShopsStockReport存放数据库元素信息，也就是只取指定ID号的那个外键的信息
函数吧
