Re: oracle alter table question

One way is to do this:

alter table rename the column to a new name. atler table add column with the old name and size you need update table1 set table1.data=table1.tempcolumn; then delete the tempcolumn and let that finish, takes a while. Then do a MOVE table to the same tablespace.

It will work. Now a VARCHAR2 should be able to gro no problem anyway... uping a size on a VARCHAR2 does nothing to how the data is stored. Not sure why you can not do that unless it is a CHAR
