Description:        Exception Issue
Details: 

I am defining Exception blocks.  When I put something that others in the
when clause, it will not compile. The others clause works fine.

The following is working fine.
BEGIN

PPSDATA.member_date_of_birth=date(substr(ROWDATA.inline,55,4)||'-'||
substr(ROWDATA.inline,59,2)||'-'||substr(ROWDATA.inline,61,2));
EXCEPTION WHEN OTHERS THEN
   ERRORCODE:='Y';
   PPSERROR.current_month_error:='*';
END;

The following is not working fine.
BEGIN
select count(*) into cnt_county from county_code
  where county_code = PPSERROR.member_county_code;
EXCEPTION
WHEN no_data then
  PPSERROR.member_county_code_error:='*';
  RAISE NOTICE '  ---county_code_error out %', PPSERROR.member_county_code;
  ERRORCODE:='Y';
END;


I get the following error.

postgres-# language plpgsql;
ERROR:  unrecognized exception condition "no_data"
CONTEXT:  compile of PL/pgSQL function "chip_pps_data_check" near line 101

Thanks
