Question

我有一张表如下......

--------------------------------------------------------------
TRANS_TYPE_CD | Member_ID | POINT_ACCOUNT_TYPE |  TRANS_DTM
--------------------------------------------------------------
Debit         | 1702      | 10                 | 2018-12-04
Credit        | 1702      | 10                 | 2018-12-04
Debit         | 1702      | 10                 | 2018-12-04
Debit         | 1702      | 10                 | 2018-12-04
Debit         | 1702      | 10                 | 2018-12-04
------------------------------------------------------------

现在我希望从这个表中选择包含行数的数据。为此，我正在使用这个SQL ...

select rowNumber, trans_dtm, lower(trans_type_cd) as trans_type_cd
from   (
        select pttrans.trans_dtm, pttrans.trans_type_cd
             , row_number() over (partition by trans_dtm order by trans_dtm desc ) as rowNumber
        from   (
                 select * from point_trans
                 where  member_id = 1702
                 and    point_account_type = 10 
                 and    (point_type_cd is null or point_type_cd not in ('Hold' ,'RolledBack','Rolledback'))
                 and    trans_dtm between to_date('2014-06-30', 'yyyy-mm-dd') and to_date('2018-12-04', 'yyyy-mm-dd')
               ) pttrans
        fetch first 300 rows only
       )
where rowNumber between 1 and 10
order by trans_dtm desc;

但是在输出中，作为rowNumber我总是得到1 ......这就是“1和10之间的rowNumber”子句无法正常工作的原因......

我得到的结果......

rowNumber | TRANS_DTM   | TRANS_TYPE_CD
-----------------------------------------
1         | 2018-12-04 | debit
1         | 2018-12-04 | debit
1         | 2018-12-04 | debit
1         | 2018-12-04 | credit
-----------------------------------------

任何人都可以帮助我使用正确的SQL。我的要求只是获取行号并根据参数过滤掉行。

我正在使用AWS Oracle RDS ....

提前致谢...
