Create table t2([X] int)
Insert t2
select '2' union all
select '2' union all
select '1' union all
select '1' union all
select '8' 

Create table t1([C1] char(4),[C2] int)
Insert t1
select '001','3' union all
select '002','4' union all
select '001','8' union all
select '003','7' union all

select C1 from t1 group by C1 having   exists(select * from t2 where t2.X>max(t1.C2))

[最优解释]
有建表插数脚本，处理起来就是快。个人能力有限，就只会一种，等楼下补充

--Create table t2([X] int)
 --Insert t2
 --select '2' union all
 --select '2' union all
 --select '1' union all
 --select '1' union all
 --select '8' 
 
 
 --Create table t1([C1] char(4),[C2] int)
 --Insert t1
 --select '001','3' union all
 --select '002','4' union all
 --select '001','8' union all
 --select '003','7' union all
 --select '002','5' 
 
 SELECT  C1
 FROM    t1
 GROUP BY C1
 HAVING  EXISTS ( SELECT *
                  FROM   t2
                  WHERE  t2.X > MAX(t1.C2) )
 
 SELECT a.c1
 FROM 
 (SELECT c1,MAX(c2)c2
 FROM t1
 GROUP BY c1) a INNER  JOIN t2 b ON a.c2<b.x
 
 
 
 
 /*
 C1
 ----
 002 
 003 
 
 (2 行受影响)
 
 c1
 ----

 003

 */

[其他解释]
select c1 from t1 group by c1
having (select max(x) from t2)>max(c2)
