Warning: No indices selected for this bind variable ??

Question

I have a view object that is read-only and performs a JDBC connection to SQL 2000 server to get the contents of a view in the database. I need to add a couple of bind variables that I can use for searching 'ExecuteWithParams' in my JSF.
When I click 'Add' to add a bind variable, I get the subject warning. My query has the selected attributes with 'AS Emp_No' for instance. If I want to add to the where clause 'AND EMP_NO = :EmpIdVar' as I would do in the Oracle way, how can I do it in the JDBC Positional way and avoid the warning above?
Thanks!

Bug 6041448 details a problem with setting the index positions of a named bind variable when the View Object's binding style is "Oracle Positional" or "JDBC Positional".
The workaround involves not using named bind variables, and just using the ? bind variable indicators in the query without formally defining the named bind variables.
You could adopt a technique like the one described in section "10.5.2 How to Work with Named View Object Bind Variables" of the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center (at http://www.oracle.com/technology/products/adf/learnadf.html) as an alternative to using ExecuteWithParams [whose use required named bind parameters]. Instead, you would write a custom method on your view object that accepts your two parameters, then inside this method it would set the correct posititional parameters using setWhereClauseParam().
Once you've added the custom method to the view object's client interface, then you can drop the custom method from the data control palette just like the ExecuteWithParams and use it in basically the same ways.
