equal distribution of start and finish dates

Hi all
I have got 3 columns in my table- start date,finish date and cost..in the
following format...
start_date finish_date cost
12/12/2000 20/12/2000 $2000
01/09/2000 12/10/2000 $400
Now if the month and year of the start and finish date is same, the cost
remains same...
but if the month of the two dates are different, i have to distribute the
cost between the two months by calculating the cost for the number of days
for both of the months..
but i am not able to figure out how?
i am using sql 2005 ..
my table has got about 1 million rows...
pls helpQuestion. What exactly is your expected result? It's not entirely clear
from your description. I think you're saying that for December 2000 the
cost should be $2,000. For the other, it soundes like you are looking to
pro-rate the $400? If so, across what time period do you want it pro-rated
exactly?

This will handle a two-month period, anything more than that is going to
be more complicated:

Hi mita,
First, you need to create a table that holds all months in your
reporting period (or more). Something like this:
CREATE TABLE dbo.Months
(MonthStart datetime NOT NULL PRIMARY KEY,
MonthEnd datetime NOT NULL);
go
DECLARE @.TheMonth datetime;
SET @.TheMonth = '200000101'; -- Start at january 2000
WHILE @.TheMonth <= '20191231' -- End at december 2019
BEGIN;
INSERT INTO dbo.Months (MonthStart, MonthEnd)
VALUES (@.TheMonth, DATEADD(day, -1, DATEADD(month, 1, @.TheMonth)));
SET @.TheMonth = DATEADD(month, 1, @.TheMonth);
END;
The above is a one time operation, provided you never drop the table.
Don't forget to add some extra months to the table in a year or ten!
With this table in place, your query becomes something like this:
SELECT PeriodStart, PeriodEnd,
TotalCost * DATEDIFF (day, PeriodStart, PeriodEnd)
/ DATEDIFF (day, start_date, finish_date) AS cost
FROM (SELECT CASE WHEN a.start_date > b.MonthStart
THEN a.start_date
ELSE b.MonthStart
END AS PeriodStart,
CASE WHEN a.finish_date < b.MonthEnd
THEN a.finish_date
ELSE b.MonthEnd
END AS PeriodEnd,
a.start_date, a.finish_date,
a.cost AS TotalCost
FROM dbo.MyTable AS a
INNER JOIN dbo.Months AS b
ON b.MonthStart <= a.finish_date
AND b.MonthStart >= a.start_date) AS d
(Untested - see www.aspfaq.com/5006 if you prefer a tested reply)

Hi Mita,
Sorry for the delayed reply.
The error is caused by a stupid typo in my code (quoted above) - I have
one zero to many in the date constant for Jan 1st, 2000. If you change
'200000101' to '20000101', the error should go away.

Enterprise Manager Date format has changed

I am not sure how this even changed but...

Until just recently when I went into any database and listed stored
procedures I could list by the date which was in the format: mm/dd/yyyy.
This allowed me to find the most recent stored procedures as they could be
sorted to the top.

Somehow the date has been changed to: yyyy-mm-dd hh:mm:ss:kkk
(Okay I didn't know what to use for milli second, I used K's ;)

You would think that I could still sort by date and get the newest to the
top, oldest to the bottom. I can't. Something has changed the date format,
and while I can click on the data bar and change the order from ascending to
descending, it does not appear to be sorting by the date so it does me no
good.

Does anyone know:

a) how to fix this
b) what could have happened to break it?

I have no idea, except to guess that your regional settings may have
changed - I assume that EM would use them to determine date and time
formats. You might also want to check that you've installed SP3 on your
client as well.

For what it's worth, there are a couple of previous posts about similar
issues in the group archives (Google "sql enterprise manager sort date"),
but unfortunately it looks like no one ever found a good
explanation/solution.

Enterprise Manager Create Date

Folks,
When viewing the tables of the databases we have on our Server, the
values in the "Create Date" column are generally of the format
"DD/MM/YYYY HH:MM:SS". Curiously however, I just had to recreate one
of the tables, and on that table alone the create date displayed is
"YYYY-MM-DD HH:MM:SS.FFF" (FFF = fractions of a second I assume?)
Anyone know why this has changed? Could it be some kind of change of
regional settings on the Server?
Suggestions invited
Thanks

Thanks for that... but I think I may be missing something still - that
information suggests how I can format dates returned from queries...
But this is the table's create date property - internal to SQL - where
is that format defined?
Forgive me if I am still missing your point!
