Try wrapping the date in the FORMAT function so, instead of #15/01/2005#,
you have FORMAT(#15/01/2005#,"dd-mmm-yyyy").

It just might be that VBA or SQL (or both) are trying to recognise an
American date format rather than the English format.

Hey guys,

I'm trying to update some data in an Access DB from Excel using ADO & SQL.
I'd like to update some fields with a defined criteria using the WHERE
clause
in SQL, but dates seem not to work...

I use the SQL string like:

UPDATE [table] SET [field1] = 'aa', [field2] = #15/01/2005# etc... _
WHERE [field3] = 'bla' AND [field4] = #01/01/2005#

I believe that the problem is the date I'm filtering... I copied the whole
SQL string into access and did not work. But if I remove the date criteria
seems to work.

I appreciate your help.
Thanks & Bregards

Santiago
