报错如下:
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)
说数据安全有在的危险,然后关于master和slave的关系,具体的不太了解,但是查到了方法,
详见:https://blog.csdn.net/antrychme/article/details/81807407
和关于解释master和slave的关系:https://www.cnblogs.com/jirglt/p/3549047.html
具体及解决方法:
查看参数:show variables like 'log_bin_trust_function_creators';
一般是off
然后输入
set global log_bin_trust_function_creators=1;
你就可以创建函数了,如果想改回默认的,把1 改为0 就好
