从sql management studio修改表设计时出现SQL错误

Question

我在SQL Server 2008上有一个相当大的表(20多列).我正在使用Microsofts SQL Server Management Studio打开表设计视图并添加一列.添加列后,我将其在列排序中向上移动.

下面的图像显示了我添加的列以及我试图将其移动到的位置,只需将其拖动几个位置即可.

在我完成这项工作之后,当我试图打开网站时,我会遇到异常.当我添加列而不在列排序中移动它时,一切正常.

有人可以帮我解决这个问题.这是MSSQL服务器,管理工作室中的错误还是其他出错的地方？

编辑:我使用NHibernate作为ORM

通过我的计算,有一个SELECT*潜伏在你的SQL代码中的某个地方(可能在函数或它所依赖的视图中).这只是SELECT*危险的众多原因之一.这是一个类似的例子,演示一个这样的失败模式:

create table dbo.T (
    ID int not null,
    FilterID uniqueidentifier not null,
    Val1 varchar(10) not null
)
go
insert into dbo.T (ID,FilterID,Val1)
select 1,'00000000-0000-0000-0000-000000000000','abc'
go
create view dbo.V
as
    select * from dbo.T
go
create function dbo.F ()
returns table
as
    return (select ID,Val1 from dbo.V where FilterID='00000000-0000-0000-0000-000000000000')
go
select * from dbo.F()
go

以上返回单个结果行,如预期的那样.现在我们以与SSMS在幕后相同的方式执行更改:

create table dbo.Temp_T (
    ID int not null,
    Flag bit null,
    FilterID uniqueidentifier not null,
    Val1 varchar(10) not null
)
go
insert into dbo.Temp_T (ID,FilterID,Val1)
select ID,FilterID,Val1 from dbo.T
go
drop table dbo.T
go
sp_rename 'dbo.Temp_T','T'
go

现在我们再次查询我们的F函数:

select * from dbo.F()

我们得到:

将varchar值'00000000-0000-0000-0000-000000000000'转换为数据类型位时转换失败.

实际上,如果我将F函数修改为:

create function dbo.F ()
returns table
as
    return (select ID,Val1 from dbo.V where FilterID=CONVERT(uniqueidentifier,'00000000-0000-0000-0000-000000000000'))
go

我可以得到:

操作数类型冲突:uniqueidentifier与bit不兼容
