am trying to pass values through a jsp page wherein I am accessing this stored procedures by the following select ststemet
SELECT sp_build_course('ETLCRC0001:ETLCRC0010:', 'CRCSUB0001:CRCSUB0001:', 'ABC', 'minal' )
the function is as below:
CREATE OR REPLACE FUNCTION sp_build_course("varchar", "varchar", "varchar", "varchar")
RETURNS text AS

when I run it I get the following error:
ERROR: syntax error at or near "$1" at character 6
CONTEXT: PL/pgSQL function "sp_build_course" line 45 at SQL statement.

Can someone please look into the procedure and tell me where I have gone wrong.
