Answer 1

试试这个：

select PONUM, 
       LINENUM, 
       RCPTNUM ,
       SITE 
from 
( --Preparing dataset
 with tbl( PONUM, LINENUM, RCPTNUM ,SITE) as 
(select 1000,     1 ,     1 ,     'XXX' from dual
 UNION ALL
 select 1000,     1,      2,      'XXX' from dual

 UNION ALL
 Select 1001,     1,      1,      'XXX' from dual )
 ---Dataset end
 ---Query
select PONUM,
       LINENUM,
       RCPTNUM,SITE ,
       row_number()over(partition by PONUM, LINENUM,RCPTNUM,SITE order by PONUM ) rnk
from tbl
)
where rnk = 2 ;
