在MySQL中，用update join，里面有order by，会导致MySQL崩溃吗？

我现在有两个SQL文，第一个可以正常执行，第二个一执行MySQL就崩溃。。崩溃指的是：docker里面对应的那个MySQL容器直接没了，docker ps -a都看不到的那种。

第一个SQL文：

update
    cfg_dev_network_push_status as T1
inner join cfg_dev_network_bind_status as T2 on
    T1.task_id = T2.id
    and T1.del_flag = '0'
    and T1.push_type = '1'
    and T1.push_result != '0'
    and T1.push_retry_times < 3
    and T2.del_flag = '0'
    and T2.dev_id = 'theDevId'
    and T2.status = '1' set
    T1.push_retry_times = T1.push_retry_times + 1,
    T1.push_status = '1',
    T1.push_end_time = '20231010141154002',
    T1.push_result = '1',
    T1.fail_reason = '109'
order by
    T1.id asc

第二个SQL文：

update
    cfg_dev_network_push_status as T1
inner join cfg_dev_network_bind_status as T2 on
    T1.task_id = T2.id
    and T1.del_flag = '0'
    and T1.push_type = '1'
    and T1.push_result != '0'
    and T1.push_retry_times < 3
    and T2.del_flag = '0'
    and T2.dev_id = 'theDevId'
    and T2.status = '1' set
    T1.push_retry_times = T1.push_retry_times + 1,
    T1.push_status = '1',
    T1.push_end_time = '20231010141154002',
    T1.push_result = '1',
    T1.fail_reason = '109'
order by
    T1.push_status desc,
    T1.push_retry_times desc,
    T1.id asc

经测试，第二个SQL文里面，T1.push_status desc和T1.push_retry_times desc，加任意一个，都会导致MySQL崩溃，只有T1.id asc的时候，是可以正常执行的。push_status的数据类型是char(1)，数据里面非0即1。push_retry_times的数据类型是int。

数据库中两个表的数据都在50条左右，不存在内存过大的影响；直接在DBeaver中进行数据查询，不考虑锁的影响。

之后我在服务器中没找到MySQL相关崩溃的日志。。。。

所以，为啥会崩呗，求各路大神帮助~

试了一下，具体问题叫 Incorrect usage of UPDATE and ORDER BY ，意思是update语句如果有join那么是不允许order by的。不过，有点诡异的是你第1条语句居然成功了，我这边试下来你第1、2条语句都会报这个错。如果想先绕过这个问题，当下可以写成：

update
    cfg_dev_network_push_status as T1
set
    T1.push_retry_times = T1.push_retry_times + 1,
    T1.push_status = '1',
    T1.push_end_time = '20231010141154002',
    T1.push_result = '1',
    T1.fail_reason = '109'
where
    T1.del_flag = '0'
    and T1.push_type = '1'
    and T1.push_result != '0'
    and T1.push_retry_times < 3
    and T1.id in (
        select id 
        from cfg_dev_network_bind_status T2 
        where
            T2.del_flag = '0'
            and T2.dev_id = 'theDevId'
            and T2.status = '1' 
    )
order by
    T1.push_status desc,
    T1.push_retry_times desc,
    T1.id asc;

希望能帮助到你。
