SQL触发器存储过程编译错误

Question

我有一个问题是什么给了我这个错误：

Msg 547, Level 16, State 0, Procedure AddIntoClass, Line 12
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_CourseEnrolled_StudentDemographic". The conflict occurred in database "PK_Final", table "dbo.StudentDemographic", column 'StudentID'.

到目前为止，这是我的代码：

Create Procedure AddIntoClass(@StudentID int, @CourseName nvarchar(30), 

@SectionNumber nvarchar(30), @TimeOfDay nvarchar(30), @Term int)
As 
Begin
    Insert into CourseEnrolled
    Values(@StudentID, @CourseName, @SectionNumber, @TimeOfDay, @Term)
End

EXEC AddIntoClass 2, 'Biology', '1003', '2:00pm', 2

任何帮助都会得到满足，谢谢！

Answer 1

在插入CourseEnrolled表之前，学生ID值“2”应该在StudentDemographic表中可用。

您正在将CourseId值“2”插入CourseEnrolled表，该表在“StudentId”上有一个外键引用到StudentDemographic表。
