Query to pull duplicates in last 15 days

Question

I have a table with Account and Trans_date columns. I am trying to write a query to pull the accounts that are present today and also present in the last 15 days.
[SQL]
select distinct  a.*
from
    select
            SFD.ACCOUNT,
            SFD.TRANS_DATE
    FROM CIRC_RPT.VW_SUBS_FINANCIAL_DRW SFD
    WHERE  SFD.trans_date between trunc(:Enter_date) -15 and trunc(:Enter_date)
    ) a
    join
    select
            SFD.ACCOUNT,
            SFD.TRANS_DATE
            FROM CIRC_RPT.VW_SUBS_FINANCIAL_DRW SFD
    WHERE SFD.trans_date = trunc(:Enter_date)
    )b on a.account =b.account
    order by a.account
[\SQL]
This query is pulling the duplicates but it is also pulling accounts that are only present on :Enter_date(not present in the past 15 days).
Please advice on the logic. Thanks in advance for your help.

Hi,
I think you want something like this:
SELECT  *
FROM    circ_rpt.vw_subs_financial_drw p15
WHERE   trans_date  >= TRUNC (SYSDATE) - 15
AND     trans_date  <  TRUNC (SYSDATE)
AND     EXISTS (
                   SELECT  1
                   FROM    circ_rpt.vw_subs_financial_drw
                   WHERE   account = p15.account
                   AND    trans_date = TRUNC (SYSDATE)
You can use :Enter_date instead of SYSDATE, but make sure it really is a DATE.  If :enter_date is a string, then remember to use TO_DATE.
If you do a join, you'll get duplicate rows if there happen to be 2 (or more) rows for the same account dated today.
The main problem with what you posted was that the way you checked for the past 15 days:
WHERE  SFD.trans_date between trunc(:Enter_date) -15 and trunc(:Enter_date)
Any row that met the condition for occurring on :enter_date
WHERE SFD.trans_date = trunc(:Enter_date)
would also meet the other condition, since BETWEEN includes both end-points.
