请问mm_styles表不能升级怎么办啊？

升级表 mm_styles 出错,请手工执行以下升级语句后,再重新运行本升级程序:

升级SQL语句: ALTER TABLE mm_styles ADD `tplid` smallint(6) unsigned NOT NULL auto_increment, ADD `tplname` varchar(80) NOT NULL default '', ADD `tplnote` text NOT NULL, ADD `tpltype` varchar(20) default NULL, ADD `tplfilepath` varchar(80) NOT NULL default '', DROP PRIMARY KEY, ADD PRIMARY KEY (tplid), ADD INDEX `tpltype` (tpltype)

Error: Incorrect table definition; there can be only one auto column and it must be defined as a key
Errno.: 1075

我手工升级STYLES也是

提示信息

Incorrect table definition; there can be only one auto column and it must be defined as a key

重复升级3次到那里卡住了……请问我该怎么办啊？

是那个版本的supesite

提示的错误好像是说有重复的主键(Key)

升级的表错了
