无法将值NULL插入列'AccountID'，表TBLAccount'列不允许空值。 INSERT失败。该语句已终止

Question

  

无法将值NULL插入“AccountID”列，表'e-BusPassManagementSystem.dbo.TBLAccount';列不允许此处为空。 INSERT失败。   声明已经终止。！

我的SQL语句是：

ALTER PROCEDURE SetApplicationForm
@UserID int,
@InstitueName varchar(50),
@ResidentalAddress varchar(max),
@Place varchar(max),
@WorkingDays int,
@Time int,
@Photo varchar(50),
@IDProof varchar(50),
@AppliedDate datetime,
@ValiedUpTo datetime,
@CardType varchar(10),
@Cardno varchar(50),
@CardExpDate datetime
AS
begin
insert into TBLApplicationForm(UserID, InstitueName, ResidentalAddress, 
                                   Place, WorkingDays, [Time], Photo, 
                                   IDProof, AppliedDate, ValidUpTo, Status)
     values(@UserID, @InstitueName, @ResidentalAddress, 
            @Place, @WorkingDays, @Time, @Photo,
            @IDProof, @AppliedDate, @ValiedUpTo, 'PENDING')

declare @ApplicationID int

set @ApplicationID = Scope_Identity()

insert into TBLAccount(UserID, ApplicationID, CardType, CardNumber, Amount, CardExpireDate, Status)
values(@UserID, @ApplicationID, @CardType, @Cardno, '200', @CardExpDate, 'PAID')
end

C＃方法：

Answer 1

TBLAccount期待AccountID列中的非空值。您的存储过程和SetApplicationForm方法无法处理此问题。如果您希望它是自动增量ID字段，则可能已将列设置错误。

Answer 2

如果数据类型为TBLAccount.AccountID或Identity，我认为您需要将int设为bigint列。否则你需要在SP的第二个插入命令中为它指定一个值。

如果您的TBLAccount.AccountID为uiqueidentifier，请将默认值设为(newId())

Answer 3

检查表dbo.TBLAccount模式定义，您应该有一个带有NOT NULL定义的AccountID列，您可以在不更改当前代码的情况下允许null，或者在当前代码中为其设置值：
