Is there an equivalent of PostgresQL's notify and listen in MySQL? Basically, I need to listen to triggers in my Java application server.

推荐答案

否，还没有像这样的内置函数. 您需要使用诸如"read" 0/1之类的预制标志进行选择来"ping"(每1-5秒)数据库.

No, there aren't any built-in functions like these yet. You need to "ping" (every 1-5 seconds) database with selecting with premade flag like "read" 0/1. After

SELECT * FROM mytable WHERE read = 0

使用读取= 1更新它
