Among other things, your query will give incorrect result for the same street in diffeent cities (or the same city with different streets) For example:

table1 with 3 fields
streetnum streetname city

12345 bob ave New City

table2 with 3 fields
streetnum streetname city

12345 bob ave Old City
12345 paul ave New City

will show up as a match.

If you are looking at VFP tables you can concatenate all the fields as........

SELECT * FROM table1 ;
  WHERE PADR(streetnum,100)+PADR(streetname,100)+PADR(city,100) IN;
     (SELECT PADR(streetnum,100)+PADR(streetname,100)+PADR(city,100) FROM table2)

(I'm not sure of the equvalent syntax in MySql or SQL Server)
