MySql数据库SQL命令指定时间范围批量修改WordPress文章发布时间

自己修改好起始时间“2014-01-01”、随机日期范围“500天”、文章ID范围起始ID 6297结束ID 14332 修改为你自己的
然后依次执行以上SQL语句即可，可以随机生成ID范围内的文章的发布日期。

UPDATE `wp_posts` SET `post_date` = DATE_ADD('2014-1-01', INTERVAL ROUND(RAND() * 500 + 1) DAY)  WHERE `ID` between 6297 AND 14332;

update `wp_posts` set `post_modified` = `post_date` WHERE `ID` between 6297 AND 14332;

update `wp_posts` set `post_date_gmt` = `post_date` WHERE `ID` between 6297 AND 14332;

update `wp_posts` set `post_modified_gmt` = `post_modified` WHERE `ID` between 6297 AND 14332;

update `wp_posts` set `post_status` = 'publish' WHERE `ID` between 6297 AND 14332

第二部份：mysql对时间日期字段值进行逐个递增。
