MySQLErrno:1146怎么解决

DROP TABLE IF EXISTS `phpcms_ask_credit`CREATE TABLE `phpcms_ask_credit` (`cid` mediumint(8) unsigned NOT NULL auto_increment,`userid` mediumint(8) unsigned NOT NULL default \'0\',`username` char(20) NOT NULL,`premonth` smallint(5) unsigned NOT NULL default \'0\',`month` smallint(5) unsigned NOT NULL default \'0\',`preweek` smallint(5) unsigned NOT NULL default \'0\',`week` smallint(5) unsigned NOT NULL default \'0\',`addtime` int(10) unsigned NOT NULL default \'0\',PRIMARY KEY(`cid`),UNIQUE KEY `userid` (`userid`),KEY `premonth` (`premonth`,`userid`),KEY `preweek` (`preweek`,`userid`)) TYPE=MyISAM这个事建表语句，你在后台或者用phpmyadmin运行一下即可该 *** 作有风险请做好数据库备份

1、你创建的data_parts数据库，但没有在这个库创建user表

2、所以你在use data_pats后，select host,user from user会报错

3、而你在use mysql 后不报表，是因为mysql库中，存在user表
