MySQL创建函数出现1418错误解决办法总结

代码如下:

错误码: 1418
This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable) 这个是创建函数功能未开。

(you *might* want to use the less safe log_bin_trust_function_creators variable)
(0 ms taken)

分析：

根据系统提示，导致该错误的原因可能是一个安全设置方面的配置，查手册

log_bin_trust_function_creators参数缺省0，是不允许function的同步的，一般我们在配置repliaction的时候，都忘记关注这个参数，这样在master更新funtion后，slave就会报告错误，然后slave stoped。

处理过程：

登陆mysql数据库

> set global log_bin_trust_function_creators ＝ 1;
> start slave;

mysql> set og_bin_trust_function_creators =1;
ERROR 1193 (HY000): Unknown system variable 'og_bin_trust_function_creators'
mysql> set log_bin_trust_function_creators =1;
ERROR 1229 (HY000): Variable 'log_bin_trust_function_creators' is a GLOBAL variable and should be set with SET GLOBAL
mysql> set global log_bin_trust_function_creators =1;
Query OK, 0 rows affected (0.00 sec)

mysql> show variable like '%func%';

跟踪mysql的启动日志，slave正常运行，问题解决。
