在使用MySQL数据库时，有时会遇到MySQL函数不能创建的情况。下面就教您一个解决MySQL函数不能创建问题的方法，供您借鉴参考。
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)
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)
MySQL函数不能创建，是未开启功能：
- 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>

1、在MySQL中创建自定义函数报错信息如下：
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)
解决方法：
mysql>set global log_bin_trust_function_creators=1;

2、创建function时
出错信息：
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：
这是我们开启了bin-log, 我们就必须指定我们的函数是否是
1 DETERMINISTIC 不确定的
2 NO SQL 没有SQl语句，当然也不会修改数据
3 READS SQL DATA 只是读取数据，当然也不会修改数据
4 MODIFIES SQL DATA 要修改数据
5 CONTAINS SQL 包含了SQL语句
其中在function里面，只有 DETERMINISTIC, NO SQL 和 READS SQL DATA 被支持。如果我们开启了 bin-log, 我们就必须为我们的function指定一个参数。
在MySQL中创建函数时出现这种错误的解决方法：
set global log_bin_trust_function_creators=TRUE;

3、
向MySQL导入数据的时候出错
出错信息：
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：
这是我们开启了bin-log, 我们就必须指定我们的函数是否是
1 DETERMINISTIC 不确定的
2 NO SQL 没有SQl语句，当然也不会修改数据
3 READS SQL DATA 只是读取数据，当然也不会修改数据
4 MODIFIES SQL DATA 要修改数据
5 CONTAINS SQL 包含了SQL语句
其中在function里面，只有 DETERMINISTIC, NO SQL 和 READS SQL DATA 被支持。 如果我们开启了 bin-log, 我们就必须为我们的function指定一个参数。
解决方法：
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)

4、
今天要写一个函数.但没有办法建提示错误如下:
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)
解决方式:(编缉my.cnf,添加如下)
[mysqld]
log_bin_trust_routine_creators = 1
重启mysql就好了
