    Remove primary key

    This is an Oracle dababase 10.2.0.4 on solaris 10.
    I want to remove the primary keys from specific tables on certain named columns. Also I want to drop the specific named columns from the table.
    I will appreciate suggestions as to the best possible approach.


    Thanks,

    Lucky

    Check business requirement one more time...
    If sure... go and ask again...

    Drop PKs
    - Research alter table drop constraint to get rid of PK

    Drop columns
    - You should also get rid of all indexes referencing columns you want to drop
    - I would create new tables, like CTAS
