MySQL函数不能创建的解决方法(转)

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
