Subj:   Re: Another ALTER TABLE question
 
From:   Todd A. Walter

The referenced section of the manual is obsolete and has been replaced/updated in V2R4.1 documentation set. There has not been an order dependency for COMPRESS for some time but we did not catch this para in the manual until recently. I recommend the updated section as required reading for any DBA/physical designer of Teradata tables. It corrects many long standing myths about Teradata compression.

Yes, Teradata has an order to the columns, primarily so SELECT * works. The order is as defined in CREATE TABLE.

No, there is no syntax currently implemented to specify the logical column position in the table during an ALTER TABLE.

A VIEW of course can reorder the columns as already noted.
