FUNCTION account.AddMinutes does not exist

[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated c

在 /etc/my.cnf 文件里加上如下：
sql_mode='NO_ENGINE_SUBSTITUTION'
然后，重启Mysql服务就可以解决了！

This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its de 错误解决办法

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;

DROP FUNCTION IF EXISTS `AddMinutes`;
DELIMITER ;;
CREATE DEFINER=`root`@`%` FUNCTION `AddMinutes`(actualDateTime datetime, minutesToAdd int) RETURNS datetime
BEGIN
    RETURN DATE_ADD(actualDateTime, INTERVAL minutesToAdd MINUTE);
END
;;
DELIMITER ;
