RE: Use SQL to compare 2 files And Get The Order Right?

Hi Tommy

I dont have access to the iseries right now, so I can't definitely say your suggestion won't work, but I don't think it will.

I think that my dilemma is that I'm trying to order by 2 different columns.

The join part is easy. FULL OUTER JOIN returns all records and matches the duplicate records. But, when a match is not found in TableA, a null is returned in TableA.name. Thus, the joined record "Theresa null" comes before the joined record, "null Sam".

I need Sam to come before Theresa.

Essentially, I'm trying to order by TableA.name BUT if TableA.name = null, then order by TableB.name.

I'm not really sure if this can be done, but I hope so.

Thank you very much

Try something like this:

With t1 as ( Select * FROM tableA FULL OUTER JOIN tableB ON
table1.name=table2.name )
Select * from t1 order by name


Thanks,

Hi
I have 2 tables, TableA and TableB which have the same columns.
Some of the rows are duplicates in both tables.
Some of the rows in TableA are not in TableB.
Some of the rows in TableB are not in TableA.
Using FULL OUTER JOIN, I can create a view that has every row of TableA
and TableB.
Returning the rows in the correct is stumping me.
Here's a very simple example of my problem:
Assume Table A has two records:
record 1 = "Chris"
record 2 = "Dave"
record 3 = "Theresa"
Assume TableB has 2 records:
record 1 = "Dave"
record 2 = "Sam"
Select * FROM tableA FULL OUTER JOIN tableB ON table1.name=table2.name
Result is:
==========
Chris null
Dave Dave
Theresa null
null Sam
Theresa shouldn't come before Sam.
What I need is:
=============
Chris null
Dave Dave
null Sam
Theresa null
I tried all sorts of other ways. I used UNION, order by, UNION ALL, but I
can't get the order correct. Can anyone make a good suggestion?
Thank you
