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
