Flat Files and FILEDEF
by Art Greenhaus

Users who create a HOLD file in one session sometimes have found they cannot read those same files at a later time, when used in JOINs. They used FILEDEF to point to the files, but the data still appeared incorrect.

As an example, try this:
TABLE FILE CAR
PRINT COUNTRY
ON TABLE HOLD AS H1
END


The data held was as follows:

COUNTRY

-------

ENGLAND
FRANCE
ITALY
JAPAN
W GERMANY


If we re-issue the FILEDEF, and issue a JOIN, as you see here:

FILEDEF H1 DISK H1.FTM
JOIN COUNTRY IN H1 TO COUNTRY IN CAR AS J1
END

TABLE FILE H1
PRINT COUNTRY CAR
END



What you get is this:

COUNTRY CAR

------- ---

ENGLAND JAGUAR
ENGLAND JENSEN
ENGLAND TRIUMPH


Where did all the other countries go?
