Thank you for the answer John,
It is unbelievable like you are going beyond the question and also how fats you are
I studied your answer and I found interesting the use of union query
My issue is that unfortunately, the program that save previous record that I cannot modify, insert in the field ModDate" the modification date before to insert in the record in historical table
this mean that if I have the record
1; 150; 03/03/2015; 21/07/2015
That was created the 3 of March and changed today 07/21/2015
With unionquery I can retreive 2 records one is coming from Hisorical table tblOpenCreditOLD and the other one is coming from tblOpenCredit
1; 2000; 03/03/2015; 07/21/2015
1; 150; 03/03/2015; 07/21/2015
If I do the query you suggested to retrieve data how was before 03/15/2015
SELECT Key, Information
FROM qryAllRecs
WHERE Key = 1 And qryAllRecs.ModDate =
(Select Max(ModDate) From qryAllRecs As Q2
Where Q2.ModDate <= #03/15/2015#)
I will not get any record because there are no record with modification date <= to 03/15/2015
In reality the record that I would like to see is the
1; 2000; 03/03/2015; 07/21/2015
That is the record how it was before that change the 21 of march occur.
If in place of one modification there were 2 modification
My union query would give me 3 records
1; 2000; 03/03/2015; 07/21/2015
1; 150; 03/03/2015; 07/21/2015
1;500; 03/03/2015; 07/10/2015
And the record that I would like to see is the
1;500; 03/03/2015; 07/10/2015
Because this was the record before that the change of 07/10/2015 (occur)
Probably the mistake it is in the program that change the field modDate, but this is like I have the data
hope is a litle bit more clear
