Today when reload database ,it showed errors like :
ERROR 1418 (HY000) at line 33441: 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/procedure 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/procedure 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:make param global log_bin_trust_function_creators TRUE;method 1:
to set global param log_bin_trust_function_creators
mysql> show variables like 'log_bin_trust_function_creators';
+---------------------------------+-------+
| Variable_name | Value |
+---------------------------------+-------+
| log_bin_trust_function_creators | OFF |
+---------------------------------+-------+
1 row in set (0.01 sec)
mysql>
mysql> set global log_bin_trust_function_creators=1;
Query OK, 0 rows affected (0.00 sec)
mysql> show variables like 'log_bin_trust_function_creators';
+---------------------------------+-------+
| Variable_name | Value |
+---------------------------------+-------+
| log_bin_trust_function_creators | ON |
+---------------------------------+-------+
1 row in set (0.00 sec)
mysql>
but after restart mysql serive ,this setting will be unuseful .so can use method 2
method 2:
modify /etc/my.cnf file to add
log_bin_trust_function_creators=1
then restart mysql service
