YNT: Re: YNT: Re: Using bind variable within BEGIN END

Thank you guys for all replies, before asking more and taking your valuble time i need to read some more.. it would be weird not to be able to do that in such a strong db like PostgreSQL as it is, the reason of question marks is about me, not the db:) .. thanks again..

Using Python and psycopg2:

\df billing_days
                                      List of functions
  Schema |     Name     |     Result data type     |      Argument data
types       |  Type
--------+--------------+--------------------------+--------------------------------+--------
  public | billing_days | TABLE(billing_date date) | start_date date,
end_date date | normal

select * from billing_days('05/01/2017', '05/30/2017');
  billing_date
