How order of fields in the table can affect UPDATE statements?
About INSERTs - it's a good thing to specify all fields being inserted just
to prevent 'inconveniences' like you've mentioned.

Yes. create a new table with same design except for the field you'd like to
change, than copy all data into new table, drop old one and rename new one.
