How to use record type for inserting data into a table

Question

I've read through the web the following tip:
"When working with a large number of columns, using variables of type RECORD is a better approach. With this approach, you do not have to list anything in the INSERT statement, because you are inserting a variable into the table that is defined as a row from the same table."
I usually define a variable as
r_mytable     mytable%ROWTYPE;
and inside my procedure I'll set the fields I need as
r_mytable.field1 := 1;
r_mytable.field3 := 7;
and then I perform the insert as
insert into mytable
(field1,
field3)
values
(r_mytable.field1,
r_mytable.field3);
According to the tip I've copied above, how can I use the TYPE RECORD of pl/sql for achieving the same result but perhaps in a smarter way?
Thanks in advance!

Hi,
Are you looking for this?
SQL> create table table1 (id number, descr varchar2(30));
Table created
SQL>
SQL> DECLARE
  2   my_rec table1%rowtype;
  3  BEGIN
  4   my_rec.id := 1;
  5   my_rec.descr := 'TEST';
  6   insert into table1 values my_rec;
  7  END;
  8  /
PL/SQL procedure successfully completed
SQL> select * from table1;
   ID DESCR
    1 TESTWorks with UPDATE too :
SQL> DECLARE
  2   my_rec table1%rowtype;
  3  BEGIN
  4   my_rec.id := 2;
  5   my_rec.descr := 'TEST2';
  6   update table1 set row = my_rec where id = 1;
  7  END;
  8  /
PL/SQL procedure successfully completed
SQL> select * from table1;
   ID DESCR
    2 TEST2
