Does anyone has codes to calculate number of weeks between two yyyymmdd dates ?
week define as Monday to Sunday, if begin date is not Monday then 1st week is partial and all the other weeks are from Monday to Sunday until the last week equal to ending date and it can be partial too.

Dear Pro

If you compute the two dates as a number since the beginning of the year and divide that number by 7 and as integer you have two weeknumbers.
the difference is your result.

Hi Pro4GL,

What do you want to see when startdate is in week 4 on friday and enddate is in week 5 on tuesday? Should this be 1 week since it's a different week, or 0 week because there are less then 7 days in between?

You could use the Date/Time function HDIFF "Find the Number of Units Between Two Date-Time Values" which allows for a Week component (it even allows you set the first day of the week using the WEEKFIRST parameter - SET WEEKFIRST = 7). You simply have to convert the Date columns to Date/Time columns using the Date/Time function HDTTM "Convert a Date Value to a Date-Time Value". Check out the WebFOCUS Functions manual.

DEFINE FILE CAR
DT1/YYMD = '20080910';
DT2/YYMD = '20081025';

-*-- Convert Date to Date/Time
DTTM1/HYYMDS = HDTTM(DT1, 8, 'HYYMDS');
DTTM2/HYYMDS = HDTTM(DT2, 8, 'HYYMDS');

DIFF1/D6 = HDIFF(DTTM2, DTTM1, 'WEEK', 'D6');
END

TABLE FILE CAR
PRINT
COUNTRY

DT1 DT2

DTTM1 DTTM2

DIFF1
WHERE READLIMIT EQ 1
END

Get for both Starting Date and Stopping Date
1) the number of times 7 is "included in"
2) the remainder of this division
(YYMMDD is a number of Days since something around 31/12/1900, but you probably know better than I ..)
The remainder of the division gives the Day in the week : Monday is 0 and Sunday 6.
With this information Stachanov can solve your problem.
Some One-Liners will give you more concise solutions.
But it's the idea and Focus doesn't any longer need Masking Dates or INUMBEROFDAYS because the Date Format is great ( and Popular ?)

And I thought a non-production version of WF 5.3.2 was bad!

hi PRO4GL ,

We use a T_DB2_ACCT_DATE table . It is universal and can be used in any server. In that table we have a field called WK_I ( week ID) , using this column we can easily calculate the no. of weeks between any two dates.

you can ask ur admin to set up this table for you. This comes in handy and is very useful.

regards

Aravindan

I thank you for the maintenance advice, I'll do that right now, along with bringing back my Minitel to the Post Office.

You must keep that Minitel, as a portal into the old world.
