mysql 中的错误 1064，任何人都可以检查错误是什么吗？

Question

CREATE PROCEDURE insert_user(in uname varchar(20),in gender varchar(20),in email varchar(20),in phone varchar(20),in pword varchar(20),in city varchar(20)) 
BEGIN
DECLARE finished integer default 0;
Declare cnt integer default 0;
declare id integer;
DECLARE  c_cur cursor for select user_id from user;
DECLARE CONTINUE HANDLE FOR NOT FOUND SET finished = 1;
    open c_cur;
        ins_user: loop
        fetch c_cur into id;

                IF finished = 1 THEN 
                LEAVE ins_user;
                end if; 


                cnt:=id;
                end loop ins_user;
        cnt:=cnt+1;
        insert into user
        values(cnt,uname,email,phone,city,pword,gender);
END;

收到错误 #1064 - 您的 SQL 语法有误；查看与您的 MySQL 服务器版本对应的手册，了解在第 7 行 'HANDLE FOR NOT FOUND SET finished = 1; open c_cur; ins_user: loop fetch ' 附近使用的正确语法我不确定哪里出错了

Answer 1

将分隔符设置为 ; 以外的其他内容，例如：$$。这将允许解析器将整个 create 语句视为一个语句。
最后，将分隔符重新定义回;
user 是一个 keyword in MySQL。最好将 table 重命名为其他名称，或在其周围使用反引号。
有错字；应该是 HANDLER 而不是 HANDLE

尝试：

DELIMITER $$
DROP PROCEDURE IF EXISTS insert_user $$

CREATE PROCEDURE insert_user(in uname varchar(20),
                             in gender varchar(20),
                             in email varchar(20),
                             in phone varchar(20),
                             in pword varchar(20),
                             in city varchar(20)) 
BEGIN
DECLARE finished INT DEFAULT 0;
Declare cnt INT DEFAULT 0;
declare id INT;
DECLARE c_cur CURSOR FOR select user_id from `user`;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET finished = 1;
    open c_cur;
        ins_user: loop
        fetch c_cur into id;

                IF finished = 1 THEN 
                LEAVE ins_user;
                end if; 


                SET cnt:=id; -- set was missing here
                end loop ins_user;
        SET cnt:=cnt+1; -- set was missing here

        insert into `user`
        values(cnt,uname,email,phone,city,pword,gender);
END $$

DELIMITER ;
