Question

我是存储的PROCEDURE的新手，我创建了存储，但它最后说的是未定义的逗号，如果条件我的代码中我做错了我的代码中有任何错误或请在此处显示我的代码

DELIMITER //
CREATE PROCEDURE passport_information(IN passengerid VARCHAR(255),IN firstname VARCHAR(255),IN middlename VARCHAR(255),IN lastname VARCHAR(255),IN country VARCHAR(255),
    IN passportno VARCHAR(255),IN expirydate VARCHAR(255),IN createddate VARCHAR(255),IN createdby VARCHAR(255),IN modifiedby VARCHAR(255),IN operationtype VARCHAR(255))
BEGIN
set operationtype =  operationtype;

 IF(passengerid IS NULL) THEN
        SET passengerid := '';
    END IF;

 IF(firstname IS NULL) THEN
        SET firstname := '';
    END IF;
     IF(middlename IS NULL) THEN
        SET middlename := '';
    END IF;
     IF(lastname IS NULL) THEN
        SET lastname := '';
    END IF;
     IF(country IS NULL) THEN
        SET country := '';
    END IF;
     IF(passportno IS NULL) THEN
        SET passportno := '';
    END IF;
     IF(expirydate IS NULL) THEN
        SET expirydate := STR_TO_DATE('1-01-2012', '%d-%m-%Y');
    END IF;
     IF(createddate IS NULL) THEN
        SET createddate := CURDATE();
    END IF;
         IF(createdby IS NULL) THEN
        SET createdby := CURDATE();
    END IF;
     IF(modifiedby IS NULL) THEN
        SET modifiedby := '';
    END IF;

case 
when operationtype='selectall' then (select * from passport_information);
when operationtype='retrievewithid' then (select * from passport_information where PassengerID=passengerid);
when operationtype='delete' then (delete from passport_information where PassengerID=passengerid);
when operationtype='insert' then (INSERT passport_information 
    (PassengerID,Firstname,Middlename,Lastname,Country,Passportno,Expirydate,Createddate,Createdby,Modifiedby)
values (passengerid,firstname,middlename,lastname,country,passportno,expirydate,createddate,createdby,modifiedby));
when operationtype='update' then (UPDATE   passport_information SET PassengerID=passengerid,Firstname=firstname,
    Middlename=middlename,Lastname=lastname,Country=country,Passportno=passportno,Expirydate=expirydate,Createddate=createddate,Createdby=createdby,Modifiedby=modifiedby where PassengerID=passengerid);
end case;
END//
DELIMITER;

这里有很多错误，你似乎还没有决定是否使用case或if..elseif，delimiter语句需要在语句和分隔符之间留一个空格（参见end //和delimiter;）。我的偏好 - 虽然是可选的，但是在插入中包含into语句。试试这个而不是你的案例陈述

if       operationtype='selectall' then 
            select * from passport_information;
elseif operationtype='retrievewithid' then 
            select * from passport_information where PassengerID=passengerid;
elseif operationtype='delete' then 
            delete from passport_information where PassengerID=passengerid;
elseif operationtype='insert' then 
            INSERT  passport_information 
            (PassengerID,Firstname,Middlename,Lastname,Country,Passportno,Expirydate,Createddate,Createdby,Modifiedby)
            values (passengerid,firstname,middlename,lastname,country,passportno,expirydate,createddate,createdby,modifiedby);
elseif operationtype='update' then 
            UPDATE   passport_information SET PassengerID=passengerid,Firstname=firstname,
            Middlename=middlename,Lastname=lastname,Country=country,Passportno=passportno,Expirydate=expirydate,Createddate=createddate,Createdby=createdby,Modifiedby=modifiedby where PassengerID=passengerid;
end if;
END //
