[Cialug] DB2

[Tim Wilson]

It is true, it depends on the version of DB2.  In our update scripts,
any time we have to add or delete a column, we go through these steps:
1. ALTER TABLE table DROP CONSTRAINT constraint; (Do this for each constraint).
2. RENAME TABLE table TO oldtable;
3. CREATE TABLE table ...
4. INSERT INTO table ... SELECT ... FROM oldtable;
5. DROP TABLE oldtable;
