今天在我执行自定义 MySQL 函数的 SQL 时发生了错误,SQL 如下:
/**
自定义 mysql 函数 getChildList
*/
delimiter //
CREATE FUNCTION `pengwifi_wifi`.`getChildList`(rootId INT)
RETURNS varchar(1000)
BEGIN
DECLARE sTemp VARCHAR(1000);
DECLARE sTempChd VARCHAR(1000);
SET sTemp = ‘$’;
SET sTempChd =cast(rootId as CHAR);
WHILE sTempChd is not null DO
SET sTemp = concat(sTemp,’,’,sTempChd);
SELECT group_concat(id) INTO sTempChd FROM hui_class where FIND_IN_SET(parent_id,sTempChd)>0;
END WHILE;
RETURN sTemp;
END
//
报错信息 : [Err] 1418 – 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:set global log_bin_trust_function_creators=TRUE;
