Question

我花了一个小时查看代码，但是找不到失败的地方

    DELIMITER $$
    DROP PROCEDURE IF EXISTS equipos$$
    CREATE PROCEDURE equipos(IN nom varchar, IN loc varchar, IN usu varchar
, IN pass varchar, OUT mensaje varchar, OUT nombreOut varchar)
    BEGIN
    select @var:=count(*) from usuario where usu=usuario.usuario;
    if(@var=0) THEN
        INSERT INTO `usuario`(`usuario`, `contraseña`) VALUES (usu,MD5(pass));
        select @id:=usuario.idUsuario from usuario WHERE usuario.usuario=usu;
        INSERT INTO `equipo`(`nombre`, `localidad`, `idUsuario`) VALUES (nom,loc,@id);
        SET mensaje="";
        Set nombreOut=nom;
    else
    SET mensaje="ya existe ese usuario";
    END IF;
    END$$

    DELIMITER ;

给我这个错误

something mistaken in your sintax near ' IN loc varchar, IN usu varchar, IN pass varchar, OUT mensaje varchar, OUT nombr' in line 1

在声明varchar时，必须指定其最大长度。喜欢

在提及VARCHAR数据类型时，您需要指定变量的最大长度

CREATE PROCEDURE equipos(IN nom varchar(64), ...
