mysql创建函数问题

今天在整理数据时，又碰到MySQL函数不能创建的问题，以前也遇到过多次，解决是解决了，但是解决办法总是记不住，也没有很好地写下来，以至于每次都要再次Google，耗时耗力，这次终于受不了了，还是选择写出来：

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)

建立不了函数，是未开启功能：

SQL code

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>







搞定！
