2、错误原因

SELECT
  stu_id,
  (SELECT
    stu_name
  FROM
    t_student_info t
  WHERE t_student_info.stu_id = t.stu_id) stu_name
FROM
  t_student_info t,

WHERE t.`stu_id` = t0.`stu_id` 

无法区别stu_id是属于哪张表，导致模糊不清

SELECT
	t0.stu_id,
	(SELECT t.stu_name FROM t_student_info t WHERE t.stu_id = t1.stu_id) stu_name
FROM
	t_student_info t1,
	t_score_info t0
WHERE
	t1.`stu_id` = t0.`stu_id`
