MySQL数据库开启、关闭、查看函数功能的方法

ERROR 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)

SET GLOBAL log_bin_trust_function_creators=1;

SET GLOBAL log_bin_trust_function_creators=0;

show variables like '%func%';
