Getting date list in a range in PostgreSQL

Question

I\'d like to get the list of days between the two dates (including them) in a PostgreSQL database. For example, if I had:

• start date: 29 june

Answer 1

This PLpg/SQL function would do the trick:

CREATE OR REPLACE FUNCTION getDateList(date1 date, date2 date)
RETURNS SETOF date AS
$BODY$
DECLARE
    count integer;
    lower_limit integer :=  0;
    upper_limit integer :=  date2 - date1;
BEGIN
    FOR count IN lower_limit..upper_limit LOOP
        RETURN NEXT date1 + count;
    END LOOP;
    RETURN;
END;
$BODY$
LANGUAGE plpgsql VOLATILE
