SQLServer用存储过程实现插入更新数据示例

Create proc Insert_Update 

@Id varchar(20), 

@Name varchar(20), 

@Telephone varchar(20), 

@Address varchar(20), 

@Job varchar(20), 

@returnValue int output 

as 

declare 

@tmpName varchar(20), 

@tmpTelephone varchar(20),


@tmpJob varchar(20),

@tmpAddress varchar(20)

if exists(select * from dbo.DemoData where id=@Id) 

begin 

select @tmpName=Name,@tmpTelephone=Telephone,@tmpAddress=Address,@tmpJob=Job from dbo.DemoData where id=@Id 

if ((@tmpName=@Name) and (@tmpTelephone=@Telephone) and (@tmpAddress=@Address)and (@tmpJob=@Job)) 

begin 

set @returnValue=0 --有相同的数据，直接返回值 

end 

else 

begin 

update dbo.DemoData set Name=@Name,Telephone=@Telephone,Address=@Address,Job=@Job where id=@Id 

set @returnValue=2 --有主键相同的数据，进行更新处理 

end 

end 

else 

begin 

insert into dbo.DemoData values(@Id,@Name,@Telephone,@Address,@Job) 

set @returnValue=1 --没有相同的数据，进行插入处理 

end

declare @returnValue int 
exec Insert_Update '15','hugh15','3823345','长安街','副部长',@returnValue output 
select @returnValue
