Kind of an easy question, but I've been looking through my materials and can't find an answer.

If I join two tables together that have the same fields, how can I tell Focus which field I want from which table in my PRINT statement?

Is it something like:
JOIN FIELD IN TABLEA TO FIELD IN TABLEB
TABLE FILE TABLEA
PRINT TABLEA.FIELD
TABLEB.NAME
END

?

Not sure if this is what you are asking, but you should be able to put the tablename.fieldname to get the field you need.

If it is a inner join it would not matter.
But the way you are trying to do this is almost correct, just change the names to 'tablea.field' with the quotes.

Use tags:
JOIN SSN IN FILE1 TAG A TO SSN IN FILE2 TAG B AS J3

TABLE FILE FILE1
PRINT B.SSN
BY A.SSN
END

Within Focus code there is a number of different ways to refer to fields:

JOIN FIELD IN TABLEA TO FIELD IN TABLEB
TABLE FILE TABLEA
PRINT TABLEA.FIELD
TABLEB.NAME
END

Would be correct, if NAME is in TABLEB.
As an example

TABLE FILE CAR
PRINT COUNTRY
ON TABLE HOLD FORMAT FOCUS
END
JOIN 
    COUNTRY IN HOLD TAG FILE1
TO  COUNTRY IN CAR TAG FILE2 AS JOIN1
END
TABLE FILE CAR
PRINT
-* for host file, these are the same
      COUNTRY
      HOLD.COUNTRY
      HOLD.SEG01.COUNTRY
      FILE1.COUNTRY
-* for XREF, these are the same
      CAR.COUNTRY
      CAR.ORIGIN.COUNTRY
      FILE2.COUNTRY
END

Thank you all. This is very helpful.
