本文章来给大家介绍关于MySQL创建函数出现1418错误解决方法,出现这种问题我们只要简单的一句就可以解决了.
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
