ERROR 1418 (HY000): This function has none of DETERMINISTIC

在Mysql集群中创建Function出现如下错误：

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

如果我们开启了 bin-log, 我们就必须为我们的function指定一个参数   

解决办法：   

set global log_bin_trust_function_creators = 1;
