Interactive Reort with DATE logic

Question

Hi,
I have a Interactive Report having the following criteria.
Let's suppose report is based on EMP table and it has a date field called EMP_DATE
My week start from Monday to Sunday.
*1. Current Week*
Feb 01 - Monday
Feb 05 - Friday
Feb 07 - Sunday
when I run the report any day from Monday (Feb 01) to Sunday (Feb 07), it should fetch all the employees whose EMP_DATE falls between the current week Monday (Feb 01) & Friday (Feb 05).
*2. Next Week*
Feb 08 - Monday
Feb 12 - Friday
Feb 14 - Sunday
when I run the report any day from Monday (Feb 01) to Sunday (Feb 07), it should fetch all the employees whose EMP_DATE falls between the next week Monday (Feb 08) & Friday (Feb 12).
*3. Previous 3rd Week*
Jan 11 - Monday
Jan 15 - Friday
Jan 17 - Sunday
when I run the report any day from Monday (Feb 01) to Sunday (Feb 07), it should fetch all the employees whose EMP_DATE falls between the previous 3rd week Monday (Jan 11) & Friday (Jan 15).
if anyone has implemented this kind of logic??, appreciate your feedback..
Thanks,
Deepak

Hi
After a slight amendment, here you go...
1.
WITH my_dates AS (SELECT TRUNC(SYSDATE)+LEVEL-20 dt
                  FROM dual
                  CONNECT BY LEVEL <= 20)
SELECT dt
FROM   my_dates
WHERE  dt BETWEEN NEXT_DAY(TO_DATE(:d)-7,'Monday')
          AND     NEXT_DAY(TO_DATE(:d)-3,'Friday');2.
WITH my_dates AS (SELECT TRUNC(SYSDATE)+LEVEL-7 dt
                  FROM dual
                  CONNECT BY LEVEL <= 20)
SELECT dt
FROM   my_dates
WHERE  dt BETWEEN NEXT_DAY(TO_DATE(:d),'Monday')
          AND     NEXT_DAY(TO_DATE(:d)+4,'Friday'); 3.
WITH my_dates AS (SELECT TRUNC(SYSDATE)+LEVEL-50 dt
                  FROM dual
                  CONNECT BY LEVEL <= 50)
SELECT dt
FROM   my_dates
WHERE  dt BETWEEN NEXT_DAY(TO_DATE(:d)-28,'Monday')
          AND     NEXT_DAY(TO_DATE(:d)-24,'Friday'); To fit this into your reports, replace the :d variable with TRUNC(SYSDATE) and dt with emp_date. Remove the WITH clause and you should be sorted.
Cheers
Ben
