Then I would use Cdate(field)

In an update query use:

IIF(len(stringdate)<7,Cdate(stringdate&"-2000"),Cdate(stringdate))

You need to know about a couple of functions to do this and I would create a new field (always advisable as is a backupo before you start) Then you can update the new field with an update update query.

UPDATE mytable
SET mynewdate = iif(isdate(myolddatefield), cdate(myolddatefield),cdate(myolddatefield & "-2001")

Change the update query so it does a select with the update to part as another field and past some of the datefield and calculated field as an example of where they are going wrong, also, what version of Access is it?

Hi Nico5038.
I tried you answer and it shows 2001properly and that is what I need.
I will post this question again to allocate points to you.

Thanks Taras.

Thanks for the gesture ;-)

Both solution will work, but both have the same "problem" that an invalid date won't be processed correctly.
You need to be sure that no Nulls or other garbage is in this field.
From that point of view you should first run a select query like:
SELECT iif(isdate(myolddatefield), "Yes",IIF(IsDate(myolddatefield & "-2001"),"Yes","No")) AS DateOK From tblWithDate WHERE DateOK = "No";

This will show the problem fields.
