Sql server 与表中的插入相关

当我想插入包含属性的表（

VehicleWheel

）时

VehicleWheelId int

vehiclehelname varchar（20））

如果自动生成

Id

，并且我想插入名称，则会发生错误：

无法在表中插入标识列的显式值 当IDENTITY_INSERT设置为OFF时为“VehicleWheel”

请给我回复我如何克服这个错误

谢谢……

错误清楚地说明了问题所在（插入列列表中的标识列VehicleID）

将insert语句更改为：

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----------

因此，SP现在应该是：

Insert into VehicleWheel (VehicleWheelName) values (@vehicleWheelName)

您需要将IDENTITY INSERT设置为ON，我不知道，感觉错误很明显

您可以使用以下方法执行此操作：

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----------
