Looking for changes in records after update

Hello,

I am trying to find changes in one table by using another table. The
first table has the "live" data. The second table has the
"historical" data.

I am trying to find any changes that may have taken place after
running an update query. The problem is, I need to find changes in
the whole record, not just a single field, or I would use the
unmatched query.

You can still use the unmatched query, but first create two queries:
each one for one of your tables, and it will concatenate all the table
values into a single column:
select CStr(CustomerID) & "-" & CustomerName & "-" & City & "-" &
State ... etc. ... as AllData
Then choose these two queries for the unmatched query.

Tom, It didn't work.

Here's what I have:

Query2:
SELECT CStr([bin] & ", " & [bsc] & ", " & [title] & ", " & [r_pnec] &
", " & [r_snec] & ", " & [a_rtabbr]) AS Astr
FROM tblAMD;

Query3:
SELECT CStr([bin] & ", " & [bsc] & ", " & [title] & ", " & [r_pnec] &
", " & [r_snec] & ", " & [a_rtabbr]) AS Bstr
FROM tblAMDHIST;

Query4:
SELECT Query3.Bstr
FROM Query3 LEFT JOIN Query2 ON Query3.Bstr = Query2.Astr
WHERE (((Query2.Astr) Is Null));

Reversing Query4 has no effect. Both versions produce no results, but
I know there are at least 5 changes.
