Hi,
  I created a table "test" with a few fields some time ago. One of the field in this table is called "name" and the type was set to be char(20). For some reason, I need to extend this field to be char(40). Since the table has already got lots of data, I wonder what is the easieast way to do this modification while keep all the existing data. Do I HAVE TO create a new table and copy everything over and so on?
  Thanks for your time!

Yes,you'll have to recreate the table. There is no way in MS SQL to modify column of existing table.
Rename existing table, create new table under old name and then insert into new table from renamed.
