Creating a function

[Glenn Schultz <glenn@xxxxxxxxxx>]

Hi,

I am trying to create a function to bin based on user value and I am stuck.  I followed the

postgres create function tutoriall but I am missing something.  Any help would be appreciated as I think I am just going further off course at this point

CREATE FUNCTION "IncentiveBin"(in Gwac double precision, 

 in MtgRaate double precision, 

 in BinSize double precision)

  RETURNS double precision

    LANGUAGE 'sql'

    VOLATILE PARALLEL SAFE 

AS

$function$

BEGIN

ceiling((Gwac - MtgRate)/BinSize) * BinSize;

END

$function$
