相关插入在表

Question

CREATE PROCEDURE dbo.usp_InsertUpdateVehicleWheel 
(
    @vehicleWheelId int, 
    @vehicleWheelName varchar(20) 
) 
AS 
    IF @vehicleWheelId = 0 
     INSERT INTO VehicleWheel (VehicleWheelId, VehicleWheelName) 
     VALUES (@vehicleWheelId, @vehicleWheelName) 
    else 
     UPDATE VehicleWheel 
     SET VehicleWheelName = @vehicleWheelName 
     WHERE VehicleWheelId = @vehicleWheelId 

    RETURN---------- 

当我想插入含有表（VehicleWheel）属性

1. VehicleWheelId int
2. VehicleWheelName varchar(20))

其中Id被自动生成和欲插入名，则会发生错误：

当IDENTITY_INSERT设置为OFF时，无法在表 'VehicleWheel'中插入标识列的显式值。

plz向我怎么克服这种错误的答复...

感谢你.......

Answer 1

错误说清楚什么是错在INSERT列（IDENTITY列VehicleID列表）...

改变插入语句：

Insert into VehicleWheel (VehicleWheelName) values (@vehicleWheelName) 

所以SP现在是：

CREATE PROCEDURE dbo.usp_InsertUpdateVehicleWheel 
(
    @vehicleWheelId int, 
    @vehicleWheelName varchar(20) 
) 

AS 

    if @vehicleWheelId=0 
      INSERT INTO VehicleWheel (VehicleWheelName) VALUES (@vehicleWheelName) 
    ELSE 
    Update VehicleWheel set 
    VehicleWheelName = @vehicleWheelName 
    where VehicleWheelId = @vehicleWheelId 
    RETURN----------

您需要设置IDENTITY INSERT为ON时，我不知道，那感觉就像错误是显而易见的

，你可以用这个做到这一点：

SET IDENTITY_INSERT table ON
