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

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.

Have you tried an unambiguous date string like "15-Jan-2005"?

My code usually collects a date from somewhere, assigns it to a variable and
then passes it on to something like the OP's query. I was interpretting the
example in those terms and not assuming the OP was actually using a
hard-coded date :-)

I've tried both: with the format() function and also with unambiguous
dates... doesn't work...

It's quite annoying I must say... you work out your code and doesn't work
because of these format matters... :-(

I'll try assigning the contents of the cell previously to a Date variable,
but I'm not positive towards this... It's really ****ing me off!

Finally made it work!!!! a combination of lots of functions:

dim vdate as date

vdate = dateserial(year(cell), month(cell), day(cell))

sSQL = sSQL & "#" & format(vdate, "dd-mmm-yyyy") & "#"


Thanks all for the assistance

My experience tells me to collect the data as a date value rather than
text (e.g. assign to a Date variable in VBA), use a dedicated OLE DB
provider of the correct version (e.g. OLE DB for Jet 4.0), use a
Command object with a dependent Parameter object typed appropriately
(e.g. adDate for a Jet 4.0 DATETIME column), if using Jet then possibly
use the ADOX.Procedures(<n).Command method to create the Command and
Parameter objects for me, then assign the strongly-typed date value to
the stronly-typed Parameter object. In other words, I assume the OLE DB
provider is better at remembering rules on formats, type conversion,
SQL parsing, regional settings, etc than I will.

I'd go for the *international* standard format, which even Access/Jet
understands i.e.

sSQL = sSQL & "#" & Format$(vdate, "yyyy-mm-dd") & "#"

Another problem that can occur with dates results from the fact that
DATE field is actually a DATE&TIME field. Depending on how you forma
your output you might not see that a time is part of the value
Depending on how the date field gets populated you may get a time valu
as well. This will affect the selection as 1/1/5 10:15 is not the sam
as 1/1/5

Good point but you are preaching to the converted <g e.g. here's a
typical bit of my DDL, note how I have constrained my DATETIME columns
only the minimum/maximum value (as appropriate) which the data type
allows:

CREATE TABLE Earnings (
pilot_ID CHAR(10) NOT NULL
REFERENCES Pilots (pilot_ID)
ON DELETE CASCADE
ON UPDATE CASCADE,
earnings_amt DECIMAL(19,4)
DEFAULT 0 NOT NULL,
start_date DATETIME NOT NULL,
CONSTRAINT start_date_value CHECK (
HOUR(start_date) = 0
AND MINUTE(start_date) = 0
AND SECOND(start_date) = 0),
end_date DATETIME NULL,
CONSTRAINT end_date_value CHECK (
HOUR(end_date) = 23
AND MINUTE(end_date) = 59
AND SECOND(end_date) = 59),
CONSTRAINT chrono_order
CHECK (start_date < end_date),
PRIMARY KEY (pilot_ID, start_date));

You see I am a fan *really* of Jet and I use it properly <g.

Jamie.
