Re: Deploying DB2 Table Changes

You can add a column in any place using ALTER TABLE, the option is "BEFORE fieldname"

Hi Richard

At least since V5R2, the CHGPF command lets you specify a source
member
that has the changes, the data will be copied, changes made, then
data
copied back - at least, that's the effect.

If DDL with SQL, ALTER TABLE gives some options - deleting, changing,
and adding columns can be done - adding has to be at the end, IIRC.

Cheers
Vern

updates on Ibmi. Usually you move or rename the table, create new
