出现 Errno: 1062 的解决方法

最近有很多会员都有这类的问题，所以我整理发了出来，希望可以帮到大家。
出现原因1:
通常出现这类 Errno: 1062 的问题都是因为相关的数据表没有把 auto-increcement 属性给添加。（不是每个 Errno: 1062 都是这个原因）

出现问题的例子

SQL: INSERT INTO 0516cdb_posts (fid, tid, first, author, authorid, subject, dateline, message, useip, invisible, usesig, htmlon, bbcodeoff, smileyoff, parseurloff, attachment)
VALUES ('34', '317', '0', '叶子', '3', '', '1137052398', '121212', '58.218.22.136', '0', '1', '0', '-1', '-1', '', '0')
Error: Duplicate entry '17258' for key 1
Errno.: 1062

原因是因为 cdb_posts 的数据表里的属性没有添加 auto-increcement 所导致。

解决方法

1. ALTER TABLE `cdb_posts` CHANGE `pid` `pid` INT( 10 ) UNSIGNED NOT NULL AUTO_INCREMENT;

复制代码

出现像例子的问题就需要看一看到底是那个数据表没有加上 auto-increcement 。

在例子中的
INSERT INTO 0516cdb_posts (fid, tid, first, author, authorid, subject, dateline, message, useip, invisible, usesig, htmlon, bbcodeoff, smileyoff, parseurloff, attachment)
是 cdb_posts 的没有加上属性没有添加 auto-increcement

如何升级这些数据？
到后台“数据库”里的“数据库升级”，然后把相关的代码贴进，按“提交”。

以下是各类的 auto-increcement 数据表，大家可以根据问题的数据表进行升级。
cdb_ 是默认的表名前缀，如果不同大家可以自行修改。
