Unable to fetch data using dbms_hs_passthrough

yomanJul 7 2016 — edited Jul 8 2016

Hi,

I have one system running Oracle DB 11g XE with HS configured and working.

My local table "SUBORDER_EVENT" contains

suborder_code number(12)

amount number(6)

The remote DB is mysql and required dblink (OMS1) and connections configured

Remote table "SUBORDER"

code varchar(15)

amount integer(10)

I already have my suborder_code populated and need to fetch AMOUNT from remotedb OMS1 against each suborder_code in local DB. I am using the below to do that, but it is working for only one input suborder_code and giving error for more than 1

declare

  val2 varchar2(15);

  p_c integer;

  nr integer;

begin

  p_c := DBMS_HS_PASSTHROUGH.OPEN_CURSOR@oms1;

  DBMS_HS_PASSTHROUGH.PARSE@oms1 (

  p_c,

  'select selling_price from suborder

  where code = ?'

  );

  FOR rec in (select distinct SUBORDER_CODE as suborder_code

  from SUBORDER_EVENT

  where AGG_STATUS = '0' and SUBORDER_CODE = 17600900000)

  LOOP

  DBMS_HS_PASSTHROUGH.BIND_VARIABLE@oms1 (p_c, 1, rec.suborder_code);

  nr := DBMS_HS_PASSTHROUGH.FETCH_ROW@oms1(p_c);

  DBMS_HS_PASSTHROUGH.GET_VALUE@oms1(p_c, 1, val2);

    update suborder_event set amount = val2 where suborder_code = rec.suborder_code and agg_status = '0';

  END LOOP; 

  DBMS_HS_PASSTHROUGH.CLOSE_CURSOR@oms1(p_c);

END;

In above code if I remove the clause "and SUBORDER_CODE = 17600900000", it fetches multiple suborders and I get error

ORA-01403: no data found

ORA-06512: at line 21

01403. 00000 -  "no data found"

*Cause:    No data was found from the objects.

*Action:   There was no data from the objects which may be due to end of fetch.

Please advise on the resolution of this.
