报错：This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'的意思是这个版本的MySQL尚不支持的限制和/ /任何/所有子查询的：

需求：

#使用not in 关键字的子查询来查询未参加html课程最近一次考试的在读学生名单#

错误的sql语句：

SELECT `studentName`
FROM `student`
WHERE `studentNo` NOT IN(
    SELECT `studentNo` FROM `result` WHERE `subjectNo` in(
        SELECT `subjectNo` FROM `subject` WHERE `subjectName`='Html'
    ) ORDER BY `examDate` DESC LIMIT 1
)

原因在于子查询三层嵌套在 in或 not in 中使用了  limit 

但是再加上一层，绕开limit子查询就可以了！

正确代码：

#改进#
 

SELECT `studentName`
FROM `student`
WHERE `studentNo` NOT IN(
    SELECT r.`studentNo` FROM (
        SELECT * FROM `result` WHERE `subjectNo` in(
            SELECT `subjectNo` FROM `subject` WHERE `subjectName`='Html'
        ) ORDER BY `examDate` DESC LIMIT 1
    ) as r
)
