Create table fileAandfileB as (
Select field1,field2,field3,field99 from filea
Union
Select field1,field2,field3,field99 from fileb ) with data

But for what you are asking there is no *drop missing columns...


Thanks,

Subject: SQL union - is there a CPYF *DROP type of directive?
Sent by: midrange-l-bounces@xxxxxxxxxxxx



I have two files that are ALMOST identical

fileA: field1, field2, field3, field99

fileB: field1, field2, field3, field4, field99


Can I create an SQL UNION without naming fields - and have SQL drop any
fields from the second file that are NOT in the first file?

Or must I name fields (creates maintenance headaches down the road).

For example can I do something like:

create table fileAandfileB as
(select * from fileA
union
select * from fileB
) with data *drop missing columns




Thanks!
