log_bin_trust_function_creators

在从其它环境导入函数的时候发现报错,报错信息如下:

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)

本章将向大家介绍改问题的原因以及解决方法:

当我们开启binlog后,log_bin_trust_function_creators默认值为OFF:

 1 mysql> show variables like 'log_bin';
 2 +---------------+-------+
 3 | Variable_name | Value |
 4 +---------------+-------+
 5 | log_bin       | ON    |
 6 +---------------+-------+
 7 1 row in set (0.01 sec)
 8 
 9 mysql> show variables like 'log_bin_t%';
10 +---------------------------------+-------+
11 | Variable_name                   | Value |
12 +---------------------------------+-------+
13 | log_bin_trust_function_creators | OFF   |
14 +---------------------------------+-------+
15 1 row in set (0.00 sec)

从官方文档上看当开启binlog并且log_bin_trust_function_creators参数为OFF时,如果创建函数,则必须要要SUPER权限,否则创建的函数必须指定DETERMINISTIC、NO SQL、READS SQL DATA其中一个属性,否则将返回我们看到的这个错误,因此当我们需要用普通用户创建需要影响binlog的函数时,必须将log_bin_trust_function_creators参数修改为ON。
