在mysql中创建函数，报

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。

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show variables like '%func%';

然后在创建函数即可。
