Look at the Sqlite date functions. File date.c describes them.
You may find that a custom function gives you exactly what you want.

Hi Kees
Many thanks for your quick reply, but it doesn't give me the date i
want.
2006/03/31 - 1 month should be 2006/02/28
whereas
select date('2006-03-31', 'start of month','-1 month') obviously gives
me 2006/02/01
I need to be able to subtract 1 month from not just a single expression,
but from a 100s of dates that are stored in a table.
Richard - I also just spotted your email. Thanks, I agree, it is fuzzy.
However :
2006/03/31 minus 1 month : I could accept 28 Feb or 1 Mar as a
reasonable answer and I can make that point to my users.
03 March is not reasonable, I can't think of any logic that would give
me that answer and I'm not able to make any case.
Thanks
Craig

Hi
Can somebody give any explain to this please.
sqlite> select date("2006-03-31");
2006-03-31
--> correct
sqlite> select date("2006-03-31", "-1 month");
2006-03-03
--> not correct
Can anyone confirm? Any suggestions / workarounds greatfully received!
Confirmed.
Better:
select date('2006-03-31', 'start of month','-1 month');
Many thanks
