/SelectCourse/detectSelectCollision.asp, 第 26 行
--------------------------------------------------------
detectSelectCollision.asp代码如下:

忘了说明一下,我用了一个名为DetectSelectionCollision的存储过程,目的是检测选课冲突.把存储过程的代码也贴上来:
create PROCEDURE DetectSelectionCollision
@ARRANGE_ID int,
@STUDENT_ID varchar(20)
AS
declare @DAY_TIME varchar(20)
declare @ARRANGE_ID_LOCAL int
--课程冲突：
select @ARRANGE_ID_LOCAL=ARRANGE_ID from CourseSelect
where ARRANGE_ID=@ARRANGE_ID and STUDENT_ID=@STUDENT_ID

--时间冲突：
select @DAY_TIME=DAY_TIME from Arrange
where ARRANGE_ID=@ARRANGE_ID
--select * from CourseSelect
--here DAY_TIME=@DAY_TIME
SELECT @ARRANGE_ID_LOCAL=CourseSelect.ARRANGE_ID
FROM Arrange INNER JOIN
CourseSelect ON
Arrange.ARRANGE_ID = CourseSelect.ARRANGE_ID
WHERE (Arrange.DAY_TIME = @DAY_TIME)
if @ARRANGE_ID_LOCAL<>''
select ARRANGE_ID,COURSE_ID,COURSE_NAME,TEACHER_NAME from VIEW_Arrange
where ARRANGE_ID=@ARRANGE_ID
else
begin
insert into CourseSelect values(@ARRANGE_ID,@STUDENT_ID)
select ARRANGE_ID from Arrange where ARRANGE_ID=0
end
GO
