Обсуждение: Converting stored procedures from SQL Anywhere to PostGres.

I am trying to convert stored procedures from SQL Anywhere to Postgres.
I am getting error

ERROR:  syntax error at or near "return"
LINE 2: return integer AS
        ^


********** Error **********

ERROR: syntax error at or near "return"
SQL state: 42601
Character: 81

when I run this.  I'm not sure what the problem is here.  Any help would
be appreciated.


CREATE OR REPLACE FUNCTION "iss"."ConfigAddKey" (in
isscontrib.citext,pkeyname)
return integer AS
$BODY$
begin

declare l:retval integer;
declare l:id integer;

if exists(select id into l:id from iss.configkeys where keyname =
pkeyname) then
  l:retval := l:id
else
  insert into "iss".configkeys(keyname) values (pKeyname);
end if;
return retval

end;
$BODY$
LANGUAGE 'plpgsql';

Well, the languages are obviously not compatible.  You're going to
have to convert them all and to do that you're going to have a decent
understanding of both languages.  I doubt there are any automatic
tools to do it.

start here:

   ^^^ Should be returns

For a good overview see:
