已经安装了旧的论坛问卷系统的该如何升级呢?
首先覆盖文件
然后执行下面的SQL(其中可能需要改前缀,另外在RENAME TABLE语句中,需要把discuz替换成你的论坛数据库名称)
只能保留原来的问卷,答卷结果由于数据结构改动太大,故无法保留- ALTER TABLE `cdb_ques` DROP `exp` ;
- ALTER TABLE `cdb_ques` DROP `price`;
- ALTER TABLE `cdb_ques` ADD `message` TEXT NOT NULL AFTER `subject` ;
- ALTER TABLE `cdb_ques` CHANGE `qid` `topicid` INT( 10 ) UNSIGNED NOT NULL AUTO_INCREMENT;
- ALTER TABLE `cdb_ques` CHANGE `uid` `authorid` MEDIUMINT( 8 ) NOT NULL DEFAULT '0';
