How to UPDATE in ROW-style?

Hello.

How could I write something like:

  DECLARE r table%ROWTYPE;
  ...
  UPDATE table SET (table.*) = (SELECT r.*) WHERE id = r.id;

This syntax is invalid, and I cannot find another proper way to do it without explicit enumeration of table's columns.

I don't want to explicitly specify table's column to minimize later refactoring.



P.S.

The corresponding INSERT operator works fine:

  DECLARE r table%ROWTYPE;
  ...
  INSERT INTO table (SELECT r.*);

Please say if a similar syntax for UPDATE exists.
