> This only happens for select queries... Insert, update, delete does not have
> the problem.
> I have code snippet
> Command select = Command.FACTORY.createCommand("Select
> * from CUSTOMERS where CUSTOMERID = ? ");
> select.setConnection(getConnection);
> select.setParameterValue(1, new Integer(2) );
> DataObject root = select.executeQuery();
> When executeQuery() is called, I get an NPE..from
> QueryString.getParameterIndex().
> Note that the same query works when its replace text? host variable :
> Command select = Command.FACTORY.createCommand("Select
> * from CUSTOMERS where CUSTOMERID = :CUST ");
> select.setConnection(getConnection);
> select.setParameterValue("CUST", new Integer(2) );
> DataObject root = select.executeQuery();
> The trace stack is as follows:
> java.lang.NullPointerException
