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
