Gary,
 
1) That's the old way of writing pgsql functions.  I forget the
transition period - I think it was around 8.0 - the new way uses $
dollar quoting and doesn't require aliasing in pgsql althought it still
does in sql procedural.
 
2) If you are using RECORD objects, I think you need to specify the
field datatypes before you can use it.  
3) That whole record thing seems like an unnecessary step anyway.
 
 
Try instead - hope I didn't make any mistakes since I didn't test it in
my typing (you might be able to skip the declare part since I've
eradicated all the variables)
 
CREATE OR REPLACE FUNCTION vts_insert_stop(stopnum text, stopdes text,
stopeasting numeric, stopnorthing numeric, projection numeric)

  RETURNS numeric AS

$BODY$ 

DECLARE

BEGIN 

      

      INSERT INTO
vts_route_stops(stop_number,stop_description,stop_latitude,stop_longitud
e)

        SELECT stopnum, stopdes, Y(SubSel.transformed_geom),
X(SubSel.transformed_geom)

            FROM 

        (SELECT SetSRID(

          Transform(GeomFromText('POINT(' || stopeasting || ' '
stopnorthing || ')', projection), 4326),-1) AS transformed_geom) SubSel;

 

      RERTURN void;

 

END

$BODY$

  LANGUAGE 'plpgsql' VOLATILE;

Below is a function I am trying to create that will take a series of
geographic points form a UTM projection and translate it to lat/long
that's not the problem though the translation works wonderfully as a
separate select statement. I'm trying to encapsulate this into a
function now and I am getting a problem returned saying: 

 

ERROR: syntax error at or near "$2"

SQL state: 42601

Character: 137

Context: PL/pgSQL function "vts_insert_stop" line 10 at select into
variables

 

I'm not sure where I've gone sideways on this but seeing as how I'm
still learning the pgplsql syntax I figured it could be anywhere I
thought maybe someone here may have a better soloution to what I'm
trying to do or can see what I'm doin wrong.

 

 

CREATE OR REPLACE FUNCTION vts_insert_stop(text, text, numeric, numeric,
numeric)

  RETURNS numeric AS

'

 

DECLARE

      stopnum ALIAS for $1;

      stopdes ALIAS for $2;

      stopeasting ALIAS for $3;

      stopnorthing ALIAS for $4;

      projection ALIAS for $5;

      transCoord RECORD;

BEGIN

      SELECT INTO transCoord X(SubSel.transformed_geom),
Y(SubSel.transformed_geom) FROM (

        SELECT SetSRID(

          Transform(

            GeomFromText(

            ''POINT('' || stopeasting || '' '' stopnorthing || '')'',
projection

            ), 4326

          ),

        -1) AS transformed_geom) SubSel;

      

      INSERT INTO
vts_route_stops(stop_number,stop_description,stop_latitude,stop_longitud
e)

      VALUES(stopnum,stopdes,transCoord.Y,transCoord.X);

 

      RERTURN void;

 

END'

  LANGUAGE 'plpgsql' VOLATILE;
