好吧，如果你有 SQL Server 2005 或更高版本，你可以这样做

select
    SQ.s1 / SQ.s2, SQ.s1, SQ.s2
from table as t
    outer apply (select subquery1 as s1, subquery2 as s2) as SQ

如果你有 SQL 2000 那么你可以使用子查询:)

select
    SQ.s1 / SQ.s2, SQ.s1, SQ.s2
from
(
    select subquery1 as s1, subquery2 as s2
    from table as t
) as SQ
