这是我调用全站更新的源代码，一共调用8个表的更新，有兴趣的可以加以改进

[e:loop={'select * from (
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_book where newstime union
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_course where newstime union
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_soft where newstime union
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_game where newstime union
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_js where newstime union
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_templet where newstime union
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_mv where newstime union
select id,classid,titleurl,filename,title,newstime,titlepic from phome_ecms_news where newstime) a order by newstime desc limit 7',7,24,0}]
