我想将学生分配到各自的考试中心。
有没有办法做到这一点?
我有两张桌子:
学生
*
ExamCenter
| StudentID | StudentName | AllocatedCenter |
我正在尝试| CenterID | Center Name |<br>
语句,但有两个不同的参数,如下所示:
正确的查询应该是:
Insert Into Select
我想做这样的事情:
INSERT INTO Student (AllocatedCenter)
SELECT CenterName
FROM ExamCenter
WHERE CenterID = 5;
但这是语法错误的陈述,虽然我只想插入特定的INSERT INTO Student (AllocatedCenter)
WHERE StudentID = 1
SELECT CenterName
FROM ExamCenter
WHERE CenterID = 5;
有没有解决方案?
提前谢谢

您可以寻找简单的更新
UPDATE S
SET AllocatedCenter =(SELECT TOP 1 [Center Name] FROM ExamCenter WHERE CenterID= 5 ORDER BY CenterID)
FROM Student s
WHERE StudentID= 1

如果要更改现有记录,则必须使用UPDATE而不是INSERT
如果要更新记录的centername,其中studentId = 1 查询是
UPDATE Student set AllocatedCenter =
(select CenterName from ExamCenter
where CenterID=5)
WHERE StudentID = 1;
