在使用MySQL数据库时，有时会遇到MySQL函数不能创建的情况。下面就教您一个解决MySQL函数不能创建问题的方法，供您借鉴参考。

出错信息大致类似：

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)
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)

MySQL函数不能创建，是未开启功能：

mysql> show variables like '%func%';  
+---------------------------------+-------+  
| Variable_name                   | Value |  
+---------------------------------+-------+  
| log_bin_trust_function_creators | OFF   |  
+---------------------------------+-------+  
1 row in set (0.00 sec)  
 
mysql> set global log_bin_trust_function_creators=1;  
Query OK, 0 rows affected (0.00 sec)  
 
mysql> show variables like '%func%';  
+---------------------------------+-------+  
| Variable_name                   | Value |  
+---------------------------------+-------+  
| log_bin_trust_function_creators | ON    |  
+---------------------------------+-------+  
1 row in set (0.00 sec)mysql>
