Assuming both fields are character data type and the same in both tables:

delete from Table2 where Field1+Field2 in (select Field1+Field2 from Table1)

Otherwise, you will have to Transform() [or convert] them to character strings. You should also test this on copies of your tables with a subset of the data. It worked for me when I tested it.
