Reg. parameterizing VO query

Question

Hi all,
We are trying to fix some dynamic VOs in our product where bind parameters have not been used. Below are two cases where we need to parameterize VO queries that do not have where clause or have sub-queries. In these cases, would setWhereClauseParam() method help in binding the parameters?
Case 1: . I have a dynamic VO created using a PL/SQL API call in select clause where I need to bind parameters - Bind in select clause - Code is in AMImpl class
String stmtStr = "select OEF_UTILS.chk_prg_since_last_prg("
+ odeftId+ "," + PPCId + ",'OEF_TASKS'," + taskId+ ")"
+" from dual ";
ViewObject tmpVO = transaction.createViewObjectFromQueryStmt(stmtStr);
Need to parameterize 'odeftId' & 'taskId'
Case 2: Sub-query binding - Code is in AMImpl class
basePrtBsVO = this.createViewObjectFromQueryStmt("BasePrtBsVO",
"SELECT prtBsBase.tot_expense " +
",prtBsBase.net_sub_to_fee " +
",prtBsBase.capped_exp " +
"FROM XYEF_EDFF_PRTBS_ALL prtBsBase, " +
"XYEF_EDFF_ALL reconBase " +
"WHERE reconBase.period_start_dt = (SELECT MIN(recon.period_start_dt) " +
"FROM XYEF_EDFF_ALL recon " +
"WHERE recon.agreement_id = " + agrId + ") " +
" AND reconBase.current_flag = 'Y' " +
" AND prtBsBase.recon_id = reconBase.recon_id " +
" AND prtBsBase.PRTBS_DTL_ID = " + prtBsDtlId);
Need to parameterize 'agrId' & 'prtBsDtlId'
Thanks,

Answer 1

To explain more -
I have SQL queries without where clauses but with dynamic variables to be bound to query- For example in CASE1- I have a dynamic VO to query -
select OEF_UTILS.chk_prg_since_last_prg(:arg1, :arg2)
from dual;
Note that there is no where clause and I call the PL/SQL API OEF_UTILS with two dynamic parameters arg1 & arg2. My requirement is to parameterize the query. Can I use setWhereClauseParams for this?
Also case 2 is one where there are sub-queries in where clause.
