mysql 创建函数This function has none of DETERMINISTIC, NO SQL, or READS

今天在mysql 5.6上创建函数的时候 发现报错：

　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)

 原因在于是未开启函数功能：

mysql> show variables like '%func%';  
+---------------------------------+-------+  
| Variable_name                   | Value |  
+---------------------------------+-------+  
| log_bin_trust_function_creators | OFF   |  
+---------------------------------+-------+  
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    |  
+---------------------------------+-------+  
row in set (0.00 sec)mysql>

执行以上sql即可开启。
