from _CB_Orders
GROUP BY case#
HAVING COUNT (case#) >1;

select Distinct RFMS_Inv_Num, case#

任何帮助..

Answer 1

这是你想要的吗？

select RFMS_Inv_Num, case#
from _CB_Orders
where RFMS_Inv_Num <> 'AETEST' and
      case# in (select case#
                from _CB_Orders
                GROUP BY case#
                HAVING COUNT(case#) > 1
               );

有关多次出现的案例的详细信息？

Answer 2

据我了解，您正尝试按RFMS_Inv_Num和case#

进行分组

 select RFMS_Inv_Num,case#
 from _CB_Orders
 GROUP BY RFMS_Inv_Num, case#
 HAVING COUNT (*) >1;
