There are several ways I have done this, but here is one ....

CREATE OR REPLACE FUNCTION constantText(varchar, int4)
  RETURNS varchar AS
$BODY$

DECLARE
  -- txtvalue tells what domain of constants are being requested
  txtvalue ALIAS FOR $1;
  intValue ALIAS FOR $2;

BEGIN

  -- for use on any new modules requiring color translations
IF txtvalue = 'adns_std_colors' THEN
  IF intValue = -1 THEN
    RETURN 'WHITE';
  END IF;

passed


hi list,

i'm relatively new in creating stored procs and i'm having this problem:

i created a stored proc that creates an aggregated view and it  was
successfully loaded without errors. my problem was, it seems that the
parameters were not successfully passed to the procedure. anything i
missed? attached is the stored procedure and the definition of the
created view:

--- snip ---
CREATE OR REPLACE FUNCTION
    make_etms_views(start_date date, end_date date)
RETURNS void
AS $$
DECLARE

BEGIN
    raise notice 'Start Date: %', start_date;
    raise notice 'End Date: %', end_date;
    CREATE VIEW hours_worked AS
    SELECT id, b.name || ', ' || b.nickname AS resource,
        sum(EXTRACT (EPOCH FROM a.hours_actual)/3600) AS hours_worked,
        sum(a.hours_actual) as days_worked
    FROM t_timesheet a, t_resource b
    WHERE activity_id NOT IN
        ( SELECT id
            FROM t_project_activity
            WHERE name ILIKE '%leave')
    AND  a.resource_id = b.id
    AND a.date_sheet BETWEEN start_date AND end_date
    GROUP BY id, resource
    ORDER BY resource
    ;
    RETURN void;

END;
$$
LANGUAGE 'plpgsql';

View definition (you'll notice that the date_sheet params were not not
properly passed, hence the $1 and $2) :

 SELECT b.id, (b.name::text || ', '::text) || b.nickname::text AS
resource, sum(date_part('epoch'::text, a.hours_actual) / 3600::double
precision) AS hours_worked, sum(a.hours_actual) AS days_worked
   FROM t_timesheet a, t_resource b
  WHERE NOT (a.activity_id IN ( SELECT t_project_activity.id
           FROM t_project_activity
          WHERE t_project_activity.name::text ~~* '%leave'::text)) AND
a.resource_id::text = b.id::text AND a.date_sheet >= $1 AND
a.date_sheet <= $2
  GROUP BY b.id, (b.name::text || ', '::text) || b.nickname::text
  ORDER BY (b.name::text || ', '::text) || b.nickname::text;
t;


i already checked out the docs, but i'm not successful in gettnig
substantial info on the problem. anyways, any help from you guys will
be appreciated.

thanks,
