Re: Using SQL for File Record Comparison

Well in that case give your SQL statement a go.

Yup...I understand what you mean and I agree. The records in each file
are unique by mdvnda and mdmdl...there is only one record in each file
with those unique values.

Are the records unique, in the sense of mdvnda & mdmdl
If these are NOT unique then you wont have a one to one comparison from

1

file to the other file and my thinking is that record 1 on FILEA will

equal

record 1 on FILEB, but record 2, 3, 4 & 5 on FILEB has the same mdvnda

&

mdmdl as record 1 on FILEB, therefore record 1 on FILEA will not equal
records 2, 3, 4, & 5 on FILEB. Therefore the count will be 4.

Now - I've just re-read what I wrote. God I hope that makes sense.

Does this make sense? Is there a better way? I'm trying to find out

if

two files are the same. Here's my SQL statement:

SELECT count(*) FROM firstlib/mhrdclp a, secondlib/mhrdclp b where
a.mdvnda = b.mdvnda and a.mdmdl = b.mdmdl and (a.mddual <> b.mddual
or a.MDCMFRT <> b.MDCMFRT or a.MDLP <> b.MDLP or a.MDSF <> b.MDSF)

File MHRDCLP has the following fields:
mdvnda
mdmdl
mddual
mdcmfrt
mdlp
mdsf

I want to see if I have any records that match mdvnda and mdmdl have
any of the other four fields different.

Thanks!
