mysql 創建函數出錯信息如下:
Error Code: 1227. Access denied; you need (at least one of) the SUPER privilege(s) for this operation
首先檢查創建函數的功能是否開啟,檢查是否開啟創建功能的SQL如下:
-- 查看是否開啟創建函數的功能 show variables like '%func%'; -- 開啟創建函數的功能 set global log_bin_trust_function_creators = 1;
執行完SQL之后發現已經開啟了,隨檢查自己的SQL是否寫錯

DROP FUNCTION IF EXISTS `nextval`;
delimiter ;;
CREATE DEFINER=`root`@`127.0.0.1` FUNCTION `nextval`(n varchar(50)) RETURNS int(11)
begin
declare _cur int;
set _cur=(select current_value from tb_sequence where name= n);
update tb_sequence
set current_value = _cur + _increment
where name=n ;
return _cur;
end
;;
delimiter ;
