column name does not exist

Hi All,
 
I have created a stored procedure
 
CREATE OR REPLACE FUNCTION ab(integer, integer,varchar,text,integer) RETURNS text AS'
DECLARE
 ret text;
BEGIN
     if(ret is null) then
          raise notice ''invalid auxiliary tag'';
     end if;
     return ret;
END;
'LANGUAGE 'plpgsql';
 
On doing: select * from ab (1,4,"exam","abhi",5);
 
I get an error : ERROR: column "exam" does not exist.
 
 
Any idea what is going wrong? Am I missing something?
 
Thanks in Advance
Abhinav

Use single quotes.  Otherwise PostgreSQL thinks you're talking about
columns instead of literal strings:
- Hide quoted text -

select * from ab(1, 4, 'exam', 'abhi', 5);
