Issue with dynamically setting where clause in OAF

Question

Hi All,
I have a View object having the query below:
SELECT  rownum LINENUM,
        B.line_id LINE_ID,
        B.INVENTORY_ITEM_ID INVITMID ,
        B.QUANTITY_DELIVERED PICKQTY         
from   MTL_TXN_REQUEST_HEADERS A,
        MTL_TXN_REQUEST_LINES  B
  WHERE A.HEADER_ID=B.HEADER_ID
   AND A.MOVE_ORDER_TYPE=2 
   AND 'on'=:1
   AND B.TO_SUBINVENTORY_CODE=NVL(:4,B.TO_SUBINVENTORY_CODE)
   AND A.request_number=NVL(:5,A.REQUEST_NUMBER) 
UNION ALL
SELECT  rownum LINENUM,
        a.wip_entity_id LINE_ID,
        a.INVENTORY_ITEM_ID INVITMID,
        a.QUANTITY_ISSUED PICKQTY      
  FROM  WIP_REQUIREMENT_OPERATIONS a,
        eam_work_orders_v b
  WHERE a.wip_entity_id=b.wip_entity_id
     AND 'on'=:2
    AND a.ATTRIBUTE2=NVL(:4,a.ATTRIBUTE2)
  and b.wip_entity_name=NVL(:6,b.wip_entity_name)
I need to pass dynamically a condition to my where clause that i can handle it by defining two bind parameters in the vo query and can pass it but the problem is the bind variable contains a string like 1311,13112,14445 that i need to pass for a field such as B.line_id in the first query and b.wip_entity_id in the second query so when i am trying by passing the string as one value it is working fine but for value separetd by comma it is giving prob.
so i tried by passing dynamic where clause but it is everytime executing for first clause only how i can pass dynamically both the queries.
vo.setWhereClause("LINE_ID in "+wherclause);
please help me out

Hi Gaurav,
Thnaks for the reply i tried belwo way u suggested but the query is executing multiple times and i am not getting the correct data as expected.
public void processPOData (String wherclause)
             OAViewObject vo = this.getXXDPECONTAINLINESVO1();
                String query =vo.getQuery();
                String newwhereclause ="LINE_ID = "+wherclause;
                StringBuffer stringbuffer = new StringBuffer();  
            stringbuffer.append("SELECT * FROM (");
            stringbuffer.append(query);
            stringbuffer.append(") where ");
            stringbuffer.append(newwhereclause);          
    ViewDefImpl viewdefimpl = getXXDPECONTAINLINESVO1().getViewDefinition();
            viewdefimpl.setQuery(stringbuffer.toString());
             vo.reset();
             vo.clearCache();
            vo.executeQuery();
                System.out.println("where clause:"+wherclause);
in my log file the query is forming like below:
SELECT * FROM (SELECT * FROM (SELECT * FROM (SELECT * FROM ( SELECT * FROM ( SELECT  rownum LINENUM,
        B.line_id LINE_ID,
        B.INVENTORY_ITEM_ID INVITMID ,
        B.QUANTITY_DELIVERED PICKQTY ,
        B.TO_SUBINVENTORY_CODE UNLOADINGPNT,
        A.REQUEST_NUMBER RRNUM,
        NULL WORKORDNUM,
        NULL DTRNUM,
        A.description,
        A.FROM_SUBINVENTORY_CODE FROM_SUB,
        A.TO_SUBINVENTORY_CODE  TO_SUB,
        NULL SOURCE       
from   MTL_TXN_REQUEST_HEADERS A,
        MTL_TXN_REQUEST_LINES  B
  WHERE A.HEADER_ID=B.HEADER_ID
   AND A.MOVE_ORDER_TYPE=2  
UNION ALL
SELECT  rownum LINENUM,
        a.wip_entity_id LINE_ID,
        a.INVENTORY_ITEM_ID INVITMID,
        a.QUANTITY_ISSUED PICKQTY,
        a.ATTRIBUTE2 UNLOADINGPNT,
        NULL RRNUM,
        b.WIP_ENTITY_NAME WORKORDNUM,
        NULL DTRNUM,
        b.description,
        NULL FROM_SUB,
        NULL TO_SUB,      
        b.source SOURCE
  FROM  WIP_REQUIREMENT_OPERATIONS a,
        eam_work_orders_v b
  WHERE a.wip_entity_id=b.wip_entity_id ) )) where LINE_ID = 30026) where LINE_ID = 30026) where LINE_ID = 30026
But in my page i am getting all the data instead of only for line 30026, please help me out
