Haven't tried it, but:
Alter table mytable alter column mylongcolumnname for myshortnm
V5R4:

atabl.htm
The syntax diagram indicates it should be changeable, but the detail for
alter column doesn't specify.

Subject: Re: DDS versus SQL DDL question
Thanks to all who replied.
If someone has created a table with column names longer than 10
characters, and did not specify that short name, DB2 automatically
generates a short name like "CUSTO00001" ... :-o
I cannot see any way to change those short names, once they are
generated, e.g. via ALTER TABLE.
Does anyone know if this is possible, or do I just have to create a new
table (with CREATE TABLE) and then copy the data over to it?
Thanks.
