RE: Calculate the 20th of next month

Can't do....

e.g. Base Date = 12/31/2009

Extracted Day = 31;

Subtract 31 from 12/31/2009 = 11/30/2009;
Add 1 month to 11/30/2009 = 12/30/2009

Add 20 days to 12/30/2009 = 1/19/2009,

How about you extract the days from your base date field (EXTRCT). Then
subtract (SUBDUR) that amout from the date. Add one month(ADDDUR) to
the result then add 20 days to that result.

You don't need to use a SELECT - as Birgitta showed, use the SET
statement - it goes directly into the host variable. I suspect the
latter does not use any IO the way a SELECT would.

I asked about her reply, whether it should be 21 days - guess I needed
some lunch - sorry if that caused any confusion. Or maybe my calendar is
zero-based.

Another option:



Create a sub-procedure and insert the following:



/free

exec SQL

select Last_Day(current_Date) + 20 days into :dueDate

from sysibm/sysdummy1;

return dueDate;
/end-free

I'd move the date to an array or substring it, move '20' to the day

field,

add one to the month (if 13 then make 1 and add 1 to year). Return new
date.

Should be falling off a log simple..

Hi Booth.

Have you tested this for when the date is (say) January 31st?

Id normally go back to the first of the month, then add 1 month and 20
days

Cheers,
Martin

Another simple task...

I need to calculate the 20 of the next month from today, whatever today
is.

duedate = (%date() + %month(1)) - (%subdt(%date()): *d) + (%days:
20)

Seems like a choice but ... what are some of the other ways that work
easily?
