Table 'zyp.p8_label' doesn't exist
1146
解决办法：
在数据库运行这段SQL:
CREATE TABLE IF NOT EXISTS `p8_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 p8_group(usr,groupid,grouptitle,sex,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 `p8_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 p8_memberdata D ON M.uid=D.uid WHERE M.username='燃灯'
SELECT command denied to user 'aipin'@'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'aipin'@'localhost';
GRANT ALL PRIVILEGES ON * . * TO'aipin'@'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 p8_article WHERE fid='32' AND yz=1 ORDER BY list DESC LIMIT 8
Incorrect key file for table '.\sq_biyangwang\p8_article.MYI'; try to repair it
126
解决办法：
在数据库运行这段SQL:
REPAIR TABLE `p8_article `
--------------------------------------------------
第十种：
数据库连接出错:SELECT COUNT(id) AS Guestbook FROM p8_guestbook
Can't find file: './kp122799/p8_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 p8_members
Table './xianxinbing/p8_members' was created with a different version of MySQL and cannot be read

升级你的Mysql或者修复优化全部相关的数据表。
