帮手解决一下问题......
谁帮我详细的解析一下这条SQL语句
if exists (select * from dbo.sysobjects where id = object_id(N '[dbo].[FK__aspnet_Us__Appli__4D6C0117] ') and OBJECTPROPERTY(id, N 'IsForeignKey ') = 1)
ALTER TABLE [dbo].[aspnet_Users] DROP CONSTRAINT FK__aspnet_Us__Appli__4D6C0117
GO
------解决方案--------------------如果存在 aspnet_Users 表的外键 FK__aspnet_Us__Appli__4D6C0117
删除该表的外键: FK__aspnet_Us__Appli__4D6C0117
