mysql恢复数据库

执行mysql备份的脚本可能会遇到以下错误：

The following error has occurred (3020, 1):
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)
Do you want to ignore error and continue?

解决办法：

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)
