Question

I am trying to make a user defined function that returns nothing. I have the body:
select form from bookings where id=$1 where $1 is the first and only argument the function takes.

I’ve tried

create function findBookgins(character varying(100)) returns void
select form from bookings where id=$1;

and I get an error at the select. I just want the table created to be displayed.

Answer 1

You have syntax errors in your function. You need to properly quote the body of the function.

CREATE FUNCTION findBookgins(character varying(100)) RETURNS VOID AS
$$
  SELECT form FROM bookings WHERE id=$1;
$$
LANGUAGE SQL
;

I think the documentation on SQL-based functions will be particularly helpful to you.

By the way, I really can’t believe you want this particular function to return nothing. What is the point of that?
