RE: SQL Question (Comparing 2 files)

["Wills, Mike N. (TC)" <MNWills@xxxxxxxxxxxxxx>]

I got it figured out. I was missing something in my select statement,
although I completely forgot what I did now (long day yesterday ;-). Thanks.
I have another SQL question I just posted on the RPG list that I could use
some help on. ;-) ;-)

Maybe you could use exist keyword in sql like
If you want to find all the record in file 1 that not exist in file 2 then
the sql is:
SELECT A.VENNUM, A.VENDIV FROM FILE1 A WHERE NOT(EXISTS(SELECT
* FROM FILE2 B WHERE A.VENNUM=B.VENNUM))

Select b.vennum,b.divnum from file1 a, file2 b
Where not (exist(b.vennum=a.vennum))

Subject: SQL Question (Comparing 2 files)

I am comparing 2 files that should have similar records in each file. For
example file 1 has vennum and vendiv and file 2 has vennum and divnum. Both
files are directly related to each other and should have one unique matching
record in each file. I am trying to figure out which records don't have a
match in the other file. How is this done?

Is this what I should use?
SELECT *
  FROM FILE1 A EXCEPTION JOIN FILE2 B
        ON A.VENNUM = B.VENNUM AND
           A.DIVNUM = B.DIVNUM

It doesn't seem to give me the correct result set.

TIA,
Mike
