删除两个表中的数据 如何删除不了

删除两个表中的数据 怎么删除不了
SELECT * FROM `liao_addonarticle`,liao_archives where liao_addonarticle.aid=liao_archives.id and liao_addonarticle.body='' 是有数据出来的 


我写了下面的两条语句 都不行。 该怎么改的呢？

delete FROM `liao_addonarticle`,liao_archives where liao_addonarticle.aid=liao_archives.id and liao_addonarticle.body=''

delete from (SELECT * FROM `liao_addonarticle`,liao_archives where liao_addonarticle.aid=liao_archives.id and liao_addonarticle.body='')



[解决办法]

SQL code

DELETE `liao_addonarticle`,`liao_archives` FROM `liao_addonarticle` LEFT JOIN `liao_archives` ON liao_addonarticle.aid=liao_archives.id WHERE liao_addonarticle.body=''
