Access string comparison

I need to compare data in two tables. Table 1 has the full, 9-digit social security number, but Table 2 only has the last four digits. I know I could extract the last four digits of the first table in Excel using Text to Columns, but it seems like there would be a way to do this when I create the subset of data for Table 1. I'm not real fluent in SQL, but understand the principles. This will be used on a monthly basis verify vendor statements, so I'd like to automate as much as possible now.

Appreciate an answer to this one.

you can do this in access using a query like this

select table1.*,  table2.*
from table1, table2
where right([Table1].[ssn],4)=table2.[ssn]

You can use the Right function on the table 1 field:

Right(9-Digit SSN,4)

You can then compare that to Table 2

I chose your answer because it shows me how to create this four-digit field in the initial query where I am creating Table 1.

Thank you!

Capricorn1: Sorry, I just now saw your comment and realize that you indeed did provide the correct answer. I'm not very SQL literate and didn't recognize it. You certainly deserve points. Is there a way I can remedy this? Thank you.

I have no problems with splitting points. I forgot to refresh and didn't see Capricorn1's response!

That's new territory for me. I would try the request attention link under your original post. That will get to one of the moderators.
