Question

我正在尝试将数据从管道分隔文件导入到mysql。创建表工作。但是，当我尝试导入数据时，我收到此错误＆＃34; ERROR 1467（HY000）：无法从存储引擎＆＃34;中读取自动增量值。我已在网站上查看可能的错误，但任何答案。下面是我正在使用的脚本。我是MySql的新手。

SELECT 'Changing database..' as '';
use test

SELECT 'Droing table if it exists' as '';
DROP TABLE IF EXISTS table1;

CREATE TABLE IF NOT EXISTS table1
(
   id BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
   infohash VARCHAR(100) NOT NULL,
   categories VARCHAR(100) DEFAULT NULL,
   info_url VARCHAR(300) NOT NULL,
   download_url VARCHAR(300) DEFAULT NULL,
   PRIMARY KEY (id)
);

SHOW TABLES;

LOAD DATA  INFILE '/usr/Software/sample.txt'

    INTO TABLE table1
    CHARACTER SET utf8
    COLUMNS
        TERMINATED BY '|'
    LINES
        TERMINATED BY '\n'
    ;
SELECT 'Total rows in table' as '';
select count(*) from table1;

这是我得到的输出。

我不确定为什么会出现这个错误。任何人吗？

Answer 1

尝试将字段名称添加到insert语句中，如下例所示。在我看来，在sample.txt上，你不必拥有id列的值。请分享sample.txt中的一些示例行以获得更好的帮助。

LOAD DATA  INFILE '/usr/Software/sample.txt'

    INTO TABLE table1 
(infohash,categories, info_url, download_url )
    CHARACTER SET utf8
    COLUMNS
        TERMINATED BY '|'
    LINES
        TERMINATED BY '\n'
    ;

Answer 2

auto_increment列增加到其上限18446744073709551615。

Answer 3

当用户尝试在uniqe键上插入重复值时，这是一个错误。我的解决方案是，插入一个具有已定义ID（以及其他所需列）的新虚拟记录，然后将其删除。

select max(`ID`) from `table1` into @IDmax;
set @IDmax = @IDmax + 1;
insert into `table1` set `ID` = @IDmax;
delete from `table1` where `ID` = @IDmax;

ERROR 1467（HY000）：无法从存储引擎
