mysql导入数据出错

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。

 

mysql> show variables like 'log_bin_trust_function_creators';

mysql> set global log_bin_trust_function_creators=1;

Query OK, 0 rows affected (0.00 sec)
