如何在AIX上删除DB2中的多个列？

Question

What is the syntax to drop multiple columns in DB2? I tried this:

ALTER TABLE work_item DROP COLUMN (TRANSACTION_TYPE, REQUEST_TYPE, LOCATION_CODE, ROLE_ID, SUBMITTED_BY);

But it didn't work. I am running on AIX (from what I read, it looks like maybe you cannot drop columns at all on platforms other than AIX).

If I drop the columns one by one, it seems to work, but after the first three, I need to REORG the table. I want to do this in one fell swoop, with no REORG.

Is it possible?

The following works for me on DB2 9.5 on Windows, but it should work on earlier versions on AIX as well:

ALTER TABLE MYSCHEMA.ABC
DROP COLUMN B
DROP COLUMN C

Here's the documentation on the ALTER TABLE command
