1418 -This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration

今天在mysql中创建函数的时候，报错如下：

ERROR 1418 (HY000): 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)

出现这个错误的原因是，不知道啥时候开启了bin-log。

解决办法：

set global log_bin_trust_function_creators=TRUE;
