錯誤代碼：mysql中的1064

Question

我創建了一個應該執行某些操作的過程，但每次調用它時，mysql都會出現錯誤，我不知道這意味着什么。 我試圖理解它是徒勞的，這里是存儲過程對其進行操作的表結構：

CREATE  TABLE `recruitment`.`job_seeker` (
    `user_id` INT Null ,
    `fname` VARCHAR(45) Null ,
    `lname` VARCHAR(45) Null ,
    `mname` VARCHAR(45) Null ,
    `gender` VARCHAR(10) Null ,
    `dob` DATE Null ,
    `marital_status` VARCHAR(45) Null ,
    `address` VARCHAR(45) Null ,
    `city` VARCHAR(45) Null ,
    `nationality` VARCHAR(45) Null ,
    `phone` VARCHAR(45) Null ,
    `mobile` VARCHAR(45) Null ,
    `degree_id` INT Null ,
    `education` VARCHAR(100) Null ,
    `experience` VARCHAR(250) Null ,
    `other` VARCHAR(250) Null ,
    `job_target` VARCHAR(250) Null ,
    PRIMARY KEY (`user_id`) ,
    INDEX `user_id` (`user_id` ASC) ,
    INDEX `degree_id` (`degree_id` ASC) ,
    CONSTRAINT `user_id`
    FOREIGN KEY (`user_id` )
    REFERENCES `recruitment`.`user_authentication` (`user_id` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION,
    CONSTRAINT `degree_id`
    FOREIGN KEY (`degree_id` )
    REFERENCES `recruitment`.`degree` (`degree_id` )
    ON DELETE NO ACTION
    ON UPDATE NO ACTION
);

這是存儲過程：

DELIMITER $$

CREATE DEFINER=`root`@`localhost` PROCEDURE `createSeekerProfile`(in userName varchar(45),
    in fn varchar(45),in mn varchar(45), in ln varchar(45),
    in gender varchar(6),in nationality varchar(45),
    in ad varchar(45),in city varchar(45),in phone varchar(15),in mob varchar(15),

    in   maritalStatus varchar(45), in degId int, in educ varchar(100),
    in exper varchar(250), in other   varchar(250),
    in dob date,in jtarg varchar(250))
    begin
    declare returned_ID int;
    set @dyn_que = CONCAT('select user_id into @returned_ID
    from user_authentication where user_name =  ? ');
    prepare s1 from @dyn_que ;
set @usn = userName;
execute s1 using @usn ;

set @dyn_update =CONCAT('update job_seeker set fname =',fn,', lname = ',ln,' ,mname = ',mn,' ,
nationality =',nationality,',address =',ad,',city =',city,',phone=',phone,',
mobile =',mob,', gender = ',gender,',other =',other,',
degree_id =',degId,', job_target=',jtarg,', dob =',dob,', education =',educ,',
experience=',exper,', marital_status=',maritalStatus,' where user_id =@returned_ID');
prepare s2 from @dyn_update;
execute s2;
end

每當我通過以下方式致電程序時：

call createSeekerProfile('realsilhouette','robert','marie','david','male'
,'earthal','an address here','capital of earth','012178152',
'1111111111','single',2,'engineering','looking forward','determined',
'2008-7-04','Oracle CEO')

我收到一個可怕的錯誤：

Error Code: 1064
You have an error in your SQL syntax; check the manual that corresponds
to your MySQL server version for the right syntax to use near 'address here,
city =capital of earth,phone=012178152,
mobile =1111111111, gender' at line 2

但是當我嘗試在存儲過程中手動執行update語句時，它運行得很好。

新帖子：感謝上帝，最后我解決了問題，問題歸結為順序，我所做的只是按順序制作參數，雖然更新聲明不關心順序，據我所知，我'我不確定，但我確信存儲過程是精美創建的，這是新代碼：

DELIMITER $$

CREATE DEFINER=`root`@`localhost` PROCEDURE `createSeekerProfile`(
in un varchar(45),
in fn varchar(45),
in ln varchar(45), 
in mn varchar(45),
in g varchar(10),
in dateOfBirth date,
in ms varchar(45),
in ad varchar(45),
in city varchar(45),
in nat varchar(45),
in ph varchar(45),
in mob varchar(45),
in degid int,
in educ varchar(100),
in exp varchar(250),
in other varchar(250),
in jtarg varchar(250))
begin

declare returned_ID int(11);

 set @dyn_que = CONCAT('select user_id into @returned_ID from user_authentication
 where user_name =  ? ');
 prepare s1 from @dyn_que ;
 set @usn = un;
 execute s1 using @usn ;


 set @dyn_update =CONCAT('update job_seeker set fname  
 ="',fn,'",lname="',ln,'",mname="',mn,'",lname ="',ln,'",
 gender ="',g,'",dob="',dateOfBirth,'",marital_status="',ms,'",
 address="',ad,'",city="',city,'",
 nationality="',nat,'",phone="',ph,'",mobile="',mob,'",degree_id="',
 degid,'",education="',educ,'",
 experience="',exp,'",other="',other,'",job_target="',jtarg,'" 
 where user_id = @returned_ID');
 prepare stm from @dyn_update;
 execute stm;
 end $$

非常感謝

Answer 1

你忘記了引用字符串值。

例如：

concat('update yourTable
set address ="',  @address, '" 
where id = 1');

或使用功能報價

Answer 2

為我添加字符`（GRAVE ACCENT）幫助。 這不是單引號（'）

Answer 3

CREATE TABLE Order
( 
    Order_Id             integer  NOT NULL ,
    Order_Time           datetime  NULL ,
    Order_Status         char(50)  NULL ,
    Customer_Id          integer  NOT NULL 
)
