在 mysql 中，update join 语句中包含 order by 会导致 mysql 崩溃吗？
问题
在使用 update join 语句时，加入 order by 会导致 mysql 崩溃。原因不明，求助大神。

答案
在 mysql 中，update join 语句中不允许包含 order by，否则会报错 incorrect usage of update and order by。
原因
update join 语句的含义是更新加入另一个表中满足条件的行。当使用 order by 时，mysql 无法确定哪个行应该被更新。
解决方案
要避免此错误，可以将 order by 移到子查询或使用笛卡尔乘积：
update cfg_dev_network_push_status set push_retry_times = push_retry_times + 1,
