错误SQL 查询:
CREATE TABLE pre_common_member_grouppm(
uid mediumint( 8 ) unsigned NOT NULL DEFAULT '0',
gpmid smallint( 6 ) unsigned NOT NULL AUTO_INCREMENT ,
`status` tinyint( 1 ) NOT NULL DEFAULT '0',
dateline int( 10 ) unsigned NOT NULL DEFAULT '0',
PRIMARY KEY ( uid, gpmid )
) ENGINE = MYISAM DEFAULT CHARSET = utf8 AUTO_INCREMENT =1;
MySQL 返回： 
#1075 - Incorrect table definition; there can be only one auto column and it must be defined as a key
PRIMARY KEY ( uid, gpmid )
只能一个主键？
怎么备份出来的都是好几个主键的。。。
