Re: About adding a new column...

Well first of all I would strongly recommend you change the design of
your table. It's a mistake to represent data in column names because it
makes your data much harder to manipulate and maintain. Basic design
sense would indicate is that the "region" is an attribute and
"America", "Asia", etc are values. In other words one would normally
expect to see ONE column for Region and one column for Sales Value.
Presenting different regions as columns is something you should do in a
report, not in a table.

To answer your specific question, there is no single command to add a
column at a particular ordinal position. The only way to do that in a
table is to re-create the table, or maybe in this case to rename the
columns and repopulate the data. In a production application table
column order is mostly unimportant - the order is determined by the
column order in a SELECT statement, not in a table. If you feel you
have a good reason to change the column order in the table on a
non-production system then you could try using the table designer in
Enterprise Manager. EM will allow you to re-order the columns and
re-create the table for you. EM will also generate the script for you
if you want to see how it's done.

Hope this helps.
