I just noticed a couple of small typos in my code earlier

select fielda from filea inner join fileb on fielda = fieldb
                        exception join filec on fielda = fieldc
union
select fielda from filea inner join filec on fielda = fieldc
                        exception join fileb on fielda = fieldb
union
select fieldb from fileb inner join filec on fieldb = fieldc
                        exception join filea on fieldb = fielda

You are most welcome CompEng, and as Phil said it takes time, and in my case, my company has a baby box that we can play on and try things. All of the developers have a developer signon and a SECOFR signon. We can go in and try out new code, new configurations, etc. If we would crash it (and the system i is so tough, we haven’t (yet)) no big deal. Just restore and try again.

As far as SQL, you can get a MySQL database to run on a PC, and you could practice on there without risking your systems.

Have fun and Happy Learning!

I am trying to find something out there that is the top of the line when it comes to a book, an online learning and an institution that would add to my quality and speed to acquire the amount of knowledge. I don’t what to mislead you. I find this site to be the best in terms of learn and having experts like you to bounce me struggles off of and again I want to say thanks a lot. Yet at the same time it would be good to have the resource of each of the three mentioned above to be able to learn faster and be able to be a giver rather then a taker to this knowledge site. So any input would be greatly appreaciated.

Unless you need to know that it is in all three tables vs any of the two table pairings, simply testing the two table pairings will get you all of the matches.

select fielda from filea inner join fileb on fielda = fieldb
                        exception join filec on fielda = fieldc
union
select fielda from filea inner join filec on fielda = fieldc
                        exception join filec on fielda = fieldb
union
select fieldb from fileb inner join filec on fieldb = fieldc
                        exception join filec on fieldb = fielda

hope this helps

so if this is the statement

SELECT [5000ChyPhantoms].Application, [5000ChyPhantoms].OE1, [5000ChyPhantoms].PN, [IN0140 79 wOE].PN, [IN0140 79 wOE].ComprsOE
FROM 5000ChyPhantoms LEFT JOIN [IN0140 79 wOE] ON [5000ChyPhantoms].PN = [IN0140 79 wOE].PN;

What you are saying is to add in the (Select distinct colTxt from myfile) where? On the Select line after [IN0140 79 wOE].ComprsOE,distinct colTxt from myfile
Is this right or not?
