创建函数报错

• 错误描述：FUNCTION mx.getChildList does not exist
• 解决方案：数据库默认不启用函数功能，需要配置开启

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>
