我有创建过程代码。当我尝试在phpmyadmin中运行创建过程代码时,它是可行的。但是当我尝试在C#中运行时,它会返回如下错误:
您的SQL语法有错误;查看与您的MySQL服务器版本相对应的手册,以获取在'DELIMITER !!附近使用正确的语法!
创建过程代码:
DELIMITER ;;
CREATE DEFINER=`root`@`localhost` PROCEDURE `update_alldoctorname`(IN `p_doktor` VARCHAR(65) CHARSET latin5, IN `p_eski` VARCHAR(65) CHARSET latin5)
NO SQL
BEGIN
UPDATE users SET hekim=p_doktor WHERE hekim=p_eski;
UPDATE tedavi SET tedavi_doktor=p_doktor WHERE tedavi_doktor=p_eski;
UPDATE medikal SET doktor=p_doktor WHERE doktor=p_eski;
UPDATE cek_devreden SET unvan=p_doktor WHERE unvan=p_eski;
END
;;
DELIMITER ;
我该如何解决?
答案 0 :(得分:0)
在C#中,不能将DELIMITER ;;
语法与MySqlCommand
一起使用。相反,只需将CREATE PROCEDURE
语句的主体用作MySqlCommand.CommandText
并执行它即可:
using (var command = yourConnection.CreateCommand())
{
command.CommandText = @"CREATE DEFINER=`root`@`localhost` PROCEDURE `update_alldoctorname`(IN `p_doktor` VARCHAR(65) CHARSET latin5, IN `p_eski` VARCHAR(65) CHARSET latin5)
NO SQL
BEGIN
UPDATE users SET hekim=p_doktor WHERE hekim=p_eski;
UPDATE tedavi SET tedavi_doktor=p_doktor WHERE tedavi_doktor=p_eski;
UPDATE medikal SET doktor=p_doktor WHERE doktor=p_eski;
UPDATE cek_devreden SET unvan=p_doktor WHERE unvan=p_eski;
END";
command.ExecuteNonQuery();
}
