Re: Reducing a column's width

Make space. You need two tables at some point.

BTW, I'm assuming that the column is not a VARCHAR2. Being that you are a newbie, I'll just mention that a VARCHAR2 does not take up the maximum amount of space allotted for it. Each row uses only what it needs plus a very small overhead.
