N :)

Answer 1

Hi,
Yes its possible.
To add new where clause to your query.
vo.setWhereClause(null);//If you want to remove any existing programmatically added where clause.
vo.setWhereClause("Your new query");
To bind varibales (Say there are 2 bind variables),
First way to achieve this.
setWhereClauseParam(null); //Always reset it to remove existing bindings)
setWhereClauseParam(0, "Your first paramter value"); // Second parameter "Your first paramter value" is of type object.
setWhereClauseParam(1, "Your first paramter value");
In case you use "?" styly type binding, this count in above method starts with 1 instead of 0.
Second way is to put all bind variables in an object array and pass to above method.
Vector params=new Vector(2);
params.addElement("FirstParameter");
params.addElement("SecondParameter");
Now call vo.executeQuery() to fetch the results as per new query.
