finding addresses that have changed

T

Thrava

Hello everyone,

I have two tables, both have the same exact structure.

Table 1 has a customer name field and address, city, zip.
This table was from 6 months ago.

Table 2 is the same table but with updated addresses as of
last week.

I like to only query and see those customers that have a
different addresses between table 1 and 2. No matter
which table it is from.

How do I do that?

Depends on how your data is.
I assume Customer name is the primary key for both tables. A
relationship should be setup between those fields then.

Assuming you are in query builder...
To get All the customers from that are in both Table 1 and table 1 you
use a normal inner join (join properties 1).
From there to get the customers in table 1 that have a different
Click to expand...
address in table to you will need to drag the Table 1 customer name
field tot he design grid. For criteria you will need '<>
[Table2].[Customer Name]'

Also, to learn how to use queries open up Microsoft Access's help. In
the contents tab goto "Working With Queries". In this case you;d want
to read about "Creating Select Queries"

hi,
there is a query wizard for that.
click new query then find unmatched query wizard.
there is a similar query. find duplicates which will find
all entries that are the same in both tables.

Create a select Query. Name it Filter_Sub (or something Sub). Make sure the
two tables have a value unique to the records. For example a Customer ID
number or something.
Create two fields as follows:

AddressTable1: [Table1].[Address]&" "&[Table1].[Address2]&"
"&[Table1].[City]&" "&[Table1].[State]&" "&[Table1].[Zip] (or however your
fields are named)

AddressTable2: [Table2].[Address]&" "&[Table2].[Address2]&"
"&[Table2].[City]&" "&[Table2].[State]&" "&[Table2].[Zip] (or however your
fields are named)

Save this Query. Create a new Query based off this sub Query. Bring both
fields down and utilize the following criteria for [AddressTable1]:
<>[AddressTable2]

This will allow you to view changed address at any given point in time,
without having to rerun or recreate any queries. However, this allows
read-only viewing only. Also displays the data for both tables, so you have
the old address and new address.
Hope this helps.

whoops, my bad, you need to find where the address is change, not
customer name. You will have to test based on address info.
