Sql server 2005 在MicrosoftSQLServer2005中，如何读取第1列中的随机行和第2列中的随机行相等？

我有三个专栏

列标记1

柱过渡

列标记2

好吧，这并不漂亮，但我认为它符合你的要求

cte的原因是为了使sql更易读

with t1a as
    (select * 
    from tablea a
    where a.mark1 = 1
    and a.transition = 'a'),
t2b as
    (select * 
    from tablea a
    where a.mark1 = 2
    and a.transition = 'b')
select t1a.mark2 
from t1a
where mark2 in (select mark1 from t2b)
union 
select t2b.mark2
from t2b

希望我没有误解你的要求

    and a.transition = 'a'),
t2b as
    (select * 
    from tablea a
    where a.mark1 = 2
    and a.transition = 'b')
select t1a.mark2 
from t1a
where mark2 in (select mark1 from t2b)
