PgMDD: How to RETURNS TABLE

Our client asked:

I have a script that can be created directly from PgAdmin, but it is not possible to create these scripts in PgMDD.

The function has a simple structure as defined below. The important part, is the return type (TABLE)

CREATE FUNCTION function_name() RETURNS TABLE(column_name_1 integer, column_name_2 character varying)
AS
BEGIN
RETURN QUERY (SELECT id, name FROM customer);
END;

PgMDD does not allow you to to that.

Yeap, indeed PgMDD doesn’t support ANSI syntax RETURNS TABLE, but you may do this in PostgreSQL way by using OUT parameters.

There is a good article “Using RETURNS TABLE vs. OUT parameters” by Leo Hsu and Regina Obe describing this approach.

So this function may be defined like this using PgMDD:

CREATE FUNCTION function_name(
  OUT column_name_1 integer,  
  OUT column_name_2 character varying) 
RETURNS SETOF RECORD
AS
$BODY$
   RETURN QUERY (SELECT id, name FROM customer);
$BODY$;

PgMDD-1.8.0: How to use old connection profiles

Our client asked:

I lost every previously defined connection setup!! (from previous versions of MicroOLAP Database Designer for PostgreSQL)

And now we’ve added import functionality for the Connection manager. All you need to do to have all your defined connections is:
