Table 'uc.uc_pms' doesn't exist，uc_pms不存在解決

第一次安裝discuz，安裝成功後跳到首頁，報如下錯誤：

Error:Table 'ucenter.uc_pms' doesn't exist
Errno:1146
SQL::SELECT count(*) FROM `ucenter`.uc_pms WHERE (related='0' AND msgfromid>'0' OR msgfromid='0') AND msgtoid='0' AND folder='inbox' AND new='1'
查了下 ，數據庫ucenter裏沒有uc_pms表。

經過搜索，在一篇帖子裏提到的方法新建這個表：

DROP TABLE IF EXISTS uc_pms;

CREATE TABLE uc_pms (

pmid int(10) unsigned NOT NULL auto_increment,

msgfrom varchar(15) NOT NULL default '',

msgfromid mediumint(8) unsigned NOT NULL default '0',

msgtoid mediumint(8) unsigned NOT NULL default '0',

folder enum('inbox','outbox') NOT NULL default 'inbox',

new tinyint(1) NOT NULL default '0',

subject varchar(75) NOT NULL default '',

dateline int(10) unsigned NOT NULL default '0',

message text NOT NULL,

delstatus tinyint(1) unsigned NOT NULL default '0',

related int(10) unsigned NOT NULL default '0',

PRIMARY KEY(pmid),

KEY msgtoid(msgtoid,folder,dateline),

KEY msgfromid(msgfromid,folder,dateline),

KEY related (related),

KEY getnum (msgtoid,folder,delstatus)

) TYPE=MyISAM;
