[GENERAL] About SP's and parameters

[Alfonso Peniche]

Hi all:

    Is there a way to pass a tablename as a parameter to a SP?

    I'll try to explain myself. I want to create a SP that can, for
instance, do a delete from ...... so that any particular application all

it has to do is call the SP sending the table to be deleted.

    Right now I have:

CREATE FUNCTION deleteanytable (bpchar)
returns integer
as '
    begin
        delete from $1;

        return 1;
    end;'
language 'plpgsql';

If I call it:
    select deleteanytable ( mytable );

I get a message saying

ERROR:  Attribute 'mytable' not found

Thanks for your help.

P.S. It would be very interesting if a columnname could also be sent as
a parameter to the Stored Procedure.
