Prorated for an entire month?

Question

I wasn't going to go over my allotted amount.  We were upgrading our service to smart phones, with data, etc.  I don't think that makes sense to charge me an entire month for 4 days.  They should have prorated the new service with the old.  And really, would it kill Verizon to allow a few days on either side of a billing cycle to avoid all the confusing bills.  I ended up paying about $75 dollars more than I should have.  That was more than my monthly bill used to be.

Hi,
Thanks for posting the CREATE TABLE and INSERT statements. Unfortunately, they don't work. Always test your code before you post it, and correct it if necessary. You're missing the keyword VALUES in all the INSERT statements. Another error is that dday is declared as a DATE in the CREATE TABLE statement, but you're trying to insert a VARCHAR2.
Here's one way to do what you asked:
SELECT       TO_CHAR ( MIN (dday)
            , 'MON,YYYY'
            )          AS month
,       MIN (begin_volume) KEEP (DENSE_RANK FIRST ORDER BY dday)     AS month_begin_volume
,       MAX (end_volume)   KEEP (DENSE_RANK LAST  ORDER BY dday)     AS month_end_volume
FROM       test20
WHERE       dday     >= DATE '2011-02-01'
AND       dday     <  DATE '2011-03-01'
GROUP BY  TRUNC (dday, 'MONTH')
;This will give you a separate row of output for each month. In your example, the WHERE clause was restricting output to a single month, but it doesn't have to be that way.
This does not assume that begin_volume and end_volume keep getting larger as the month goes on, as in your sample data. If they did, then you wouldn't need the FIRST and LAST functions, and it would be more efficient.
