just like Access?

CREATE VIEW Faked_table
AS SELECT O.A1, O.A2, .....O.An
FROM Original_table O
here: Faked_table is the target one, and the Origianl_table is the source
table. the A1,....An is whatever you like to conserve fields.
BTW, the FAked_table isn't physically exist. but there is really physically
stored counterpart of each row of the table. It won't show up to the user.
If it's not what u want and you wanna to lose the field totally, just creat
a new table, but it's not a good
