尝试在我的数据库中插入一些数据时出现此错误。

INSERT 语句与 FOREIGN KEY 约束冲突FK_DevID_Prog。ElectricImp数据库、表dbo.Developer、列发生冲突DevID。

代码：

Create Table Developer
(
    DevID       Char(10)    Not Null,
    UserName    Char(20)    Not Null,
    DevPassword Char(20)    Not Null,
    Email       VarChar(20) Not Null,
    Country     VarChar(25) Not Null,
    ZipCode     Integer,
    CellPhone   Integer     Not Null,
    Constraint PK_DevID Primary Key(DevID)
);

--Drop Table Programme;
Create Table Programme
(
    ProgrammeID     Char(10)    Not Null,
    DevID           Char(10)    Not Null,
    ProgrammeName   VarChar(20) Not Null,
    ProgrammeCode   VarChar(20) Not Null,
    Constraint PK_ProgID Primary Key(ProgrammeID),
    Constraint FK_DevID_Prog Foreign Key(DevID) References Developer(DevID)

Insert Into 
Developer(DevID,UserName,DevPassword,Email,Country,ZipCode,CellPhone)
Values
    ('Dev123456A','Paul Wilson Diu','P@ulWilson','Paul_Wilson@yahoo.com','Philippines','12345','0277824893'),
    ('Dev123456B','Actor One','@ctor1','Actor_One@yahoo.com','New Zealand','11234','0293847567'),
    ('Dev123456C','Actor Two','@ctor2','Actor_Two@yahoo.com','USA','42562','028394576'),
    ('Dev123456D','Actor Three','@ctor3','Actor_Three@yahoo.com','USA','93847','0294857689'),
    ('Dev123456E','Actor Four','@ctor4','Actor_Four@yahoo.com','Australia','02947','0293847563'),
    ('Dev123456F','Actor Five','@ctor5','Actor_Five@gmail.com','Germany','92846','0293748123');

Insert Into 
Programme(ProgrammeID,DevID,ProgrammeName,ProgrammeCode)
Values
    ('Prog12345A','Dev123456A','Programme A','ProgCode123A'),

    ('Prog12345G','Dev123456C','Programme G','ProgCode123G'),
    ('Prog12345H','Dev123456E','Programme H','ProgCode123H');

您的数据插入 Developer 表失败，因此 Developer 表中没有任何记录。并且当您将数据插入 Program 表时，Programme.DevID 不能引用 Developer.DevID

我尝试了您的脚本插入数据，并出现错误开发人员表：

字符串或二进制数据将被截断。该语句已终止。

'Paul_Wilson@yahoo.com' Len：21 个字符，但电子邮件字段：VARCHAR(20) => 错误

您可以再次检查
