Adding a dynamic where clause using named bind variables

The following piece of code is used to set a dynamic where clause to a view object. It also shows how to set  values to the named bind parameters present in the dynamic where clause.

    public void addWhereClauseWithNamedBindParams(){
        ViewObject vo=this.getEmp1();
       
      
        vo.setWhereClause(null);
       
        vo.setWhereClause("Empno=:eNo");
        vo.defineNamedWhereClauseParam("eNo",new Integer("7369"),null);
        vo.executeQuery();
       
        vo.removeNamedWhereClauseParam("eNo");
        vo.setWhereClause(null);
    }
