以下是引用片段： 第一种：
数据库连接出错:INSERT INTO `php168_article_db` (`aid`) VALUES ('68536')
Duplicate entry '68536' for key 'PRIMARY'
1062 解决办法：
在数据库运行这段SQL:
DELETE FROM php168_article_db WHERE aid>68536
-----------------
第二种：
数据库连接出错:SELECT A.*,R.* FROM php168_article A LEFT JOIN php168_reply R ON A.aid=R.aid WHERE A.aid=65 ORDER BY R.rid ASC LIMIT 0,1
Can't create/write to file 'C:\WINDOWS\TEMP\#sql_658_0.MYD' (Errcode: 17)
1
解决办法：
在my.ini中[mysqld]里面添加一行
tmpdir="c:/mysql/temp/" 或将#sql_658_0.MYD删除后再重启Mysql服务
-----------------------------------------
第三种：
数据库连接出错:SELECT R.*,A.* FROM php168_article A LEFT JOIN php168_reply R ON A.aid=R.aid WHERE A.aid=608 ORDER BY R.topic DESC,R.orderid ASC LIMIT 0,1
Got error 28 from storage engine
1030
解决办法：
清空在my.ini中tmpdir="c:/mysql/temp/"目录下的文件，或者修改tmpdir参数指向具有足够空间目录。
--------------------------
第四种：
数据库连接出错:SELECT * FROM php168_article WHERE fid='2' ORDER BY list DESC LIMIT 8
Got error 127 from table handler
1030
解决办法：
在数据库运行这段SQL:
REPAIR TABLE `php168_article `
-----------------------------------------------
第五种：
数据库连接出错:SELECT R.*,A.* FROM php168_article A LEFT JOIN php168_reply R ON A.aid=R.aid WHERE A.aid=687 ORDER BY R.topic DESC,R.orderid ASC LIMIT 0,1
Unknown column 'R.orderid' in 'order clause'
1054
解决办法：在数据库运行这段SQL:
ALTER TABLE `php168_reply` ADD `orderid` MEDIUMINT( 8 ) NOT NULL ;
------------------------------------------
第六种：
数据库连接出错: SELECT * FROM php168_label WHERE lid='1'
Table 'zyp.php168_label' doesn't exist
1146
解决办法：
在数据库运行这段SQL:
CREATE TABLE IF NOT EXISTS `php168_label` (
`lid` int(10) NOT NULL AUTO_INCREMENT,
`name` varchar(100) NOT NULL DEFAULT '',
`ch` smallint(4) NOT NULL DEFAULT '0',
`chtype` tinyint(2) NOT NULL DEFAULT '0',
`tag` varchar(50) NOT NULL DEFAULT '',
`type` varchar(30) NOT NULL DEFAULT '',
`typesystem` tinyint(1) NOT NULL DEFAULT '0',
`code` text NOT NULL,
`divcode` text,
`hide` tinyint(1) NOT NULL DEFAULT '0',
`js_time` int(10) NOT NULL DEFAULT '0',
`uid` mediumint(7) NOT NULL DEFAULT '0',
`username` varchar(30) NOT NULL DEFAULT '',
`posttime` int(10) NOT NULL DEFAULT '0',
`pagetype` tinyint(3) NOT NULL DEFAULT '0',
`module` mediumint(6) NOT NULL DEFAULT '0',
`fid` mediumint(7) NOT NULL DEFAULT '0',
`if_js` tinyint(1) NOT NULL DEFAULT '0',
`style` varchar(40) NOT NULL DEFAULT '',
PRIMARY KEY (`lid`),
KEY `ch` (`ch`,`pagetype`,`module`,`fid`,`chtype`),
KEY `tag` (`tag`)
) ENGINE=MyISAM DEFAULT CHARSET=gbk AUTO_INCREMENT=1 ;
-----------------------------------------
第七种：
数据库连接出错:insert into php168_group(usr,groupid,grouptitle,*,ip,ipfrom,time,where_name,hide,where_id,where_fid,onl_id,sid,url,windows) values ('','','管理员','','10.0.0.39','Unknow','1143167041','','','','','','8FWKel5RHLEWStmRoesvu35BSYW6K1uH',
'http://10.0.0.39/02/index.php','|')
Incorrect integer value: '' for column 'groupid' at row 1
1366
解决办法：
在数据库运行这段SQL:
ALTER TABLE `php168_group` CHANGE `groupid` `groupid` INT( 4 ) NOT NULL AUTO_INCREMENT
-----------------------------------------------------------------------------
第八种：
数据库连接出错:SELECT M.username AS username,M.password AS password,M.salt,D.* FROM `dz`.cdb_uc_members M LEFT JOIN php168_memberdata D ON M.uid=D.uid WHERE M.username='oneuser'
SELECT command denied to user root@localhost for table 'cdb_uc_members'
1142
解决办法：
比如mysql用户名是root:在数据库运行这段SQL:
REVOKE ALL PRIVILEGES ON * . * FROM'root@localhost';
GRANT ALL PRIVILEGES ON * . * TO'root@localhost'WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;
-------------------------------------------------
第九种：
数据库连接出错:SELECT * FROM php168_article WHERE fid='32' AND yz=1 ORDER BY list DESC LIMIT 8
Incorrect key file for table '.\sq_biyangwang\php168_article.MYI'; try to repair it
126
解决办法：
在数据库运行这段SQL:
REPAIR TABLE `php168_article `
--------------------------------------------------
第十种：
数据库连接出错:SELECT COUNT(id) AS Guestbook FROM php168_guestbook
Can't find file: './kp122799/php168_guestbook.frm' (errno: 13)
1017
解决办法：
或许是权限问题，如mysql用户名是root:在数据库运行这段SQL:
REVOKE ALL PRIVILEGES ON * . * FROM 'root'@'127.0.0.1';
GRANT ALL PRIVILEGES ON * . * TO 'root'@'127.0.0.1' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;
或重新启动mysql，再不行尝试对其数据表进行修复。
-------------------
第十一种：
数据库连接出错:SELECT COUNT(uid) AS Member FROM php168_members
Table './xianxinbing/php168_members' was created with a different version of MySQL and cannot be read
1033
解决办法：
升级你的Mysql或者修复优化全部相关的数据表。
