asp sql数据库 同一表中 不同查询条件产生的 结果一起输出
如select*froma_companywherejingp='1'select*froma_companywherehot='1'select*froma_compa...
如 select * from a_company where jingp = '1'
select * from a_company where hot = '1'
select * from a_company where hy = '1'
将以上合并成一个记录集，
我用sql= "select * from (select * from a_company where jingp = '1' union select * from a_company where hot = '1' union select * from a_company where hy = '1'
)" 没有用啊！！这样做的主要是为了实现将VIP排在最前面，然后是推荐的，然后是普通的 展开
select * from a_company where hot = '1'
select * from a_company where hy = '1'
