--创建测试表
if exists (select 1 from sysobjects where id = object_id('celebrity') and type = 'U')
drop table celebrity
create table celebrity(
[id] int identity(1,1) primary key,
[type] int ,
[name] nvarchar(50),
[Date] datetime,
[Salary] decimal(18,2),
[Field_1] decimal(18,2),
[Field_2] nvarchar(100)
)
--插入初始测试数据
insert into celebrity([type],[name],[Date],[Salary],[Field_1],[Field_2])
select 0,'杜甫','2010-02-05',100,null,'贫困潦倒' union all
select 1,'杜甫',null,200,119,'大诗人' union all
