帝国cms灵动标签 sql 多栏目ID如何调用？

<div>[e:loop={"select * from p_ecms_news where classid=14 and titlepic<>'' order by newstime desc limit 1",6,24,0}]</div><div>[/e:loop]</div><div></div>

多个要用in
classid in (15,18,20)
例：
[e:loop={"select * from _yisvip__enewsclass where classid in (34,35,36) order by classid asc limit 20",0,24,0}]
