如何获得带有条件的mysql查询结果

Question

老师桌

teacher_id      teacher_name
============================
1               john
2               doe

学生桌

student_id      student_name    student_score   teacher_id
==========================================================
1               amelia          0               1
2               anderson        0               1
3               fabiano         0               1
4               ronaldo         0               2
5               peter           6               2
6               alex            0               2

结果

teacher_id      teacher_name
============================
2               doe

结果是教师记录谁的一个或多个学生分数> 0。

怎么查询这个？

感谢您的回答，对不起我的英语不好

Answer 1

一个简单的子查询就能解决问题

SELECT * FROM teacher WHERE teacher_id IN
(SELECT teacher_id FROM student WHERE student_score > 0)

也可能是INNER JOIN

Answer 2

SELECT teacher.* FROM teacher
LEFT JOIN student as student teacher.teacher_id = student.teacher_id
WHERE student.student_score > 0

希望这对您有用。
