How to use JDBC Positional Binding Style & ExecuteWithParams?

Question

Can anyone provide any help here including any documentation on how to configure this (I've checked online help and the developer guide.)
When defining multiple Bind Position variables on a View Object (using sql statement binding style: JDBC Positional), should I defined multiple bind variable names? Otherwise, if I don't, when I use ExecuteWithParams operation to create the data control, only one input variable field is displayed. I can get a single bind position variable to work, but am struggling on how to configure / get multiple bind position variables to work with ExecuteWithParams.
Here's my current configuration:
1. Define View Object with two JDBC Positional Binding Parameters
-- Bind Variables: name=parm1 (???should I define a second bind variable name???)
-- Bind Positions = 0,1
-- SQL Statement add another position var in where clause: "match (zip) against (CONCAT(?,'*') IN BOOLEAN MODE) and "match (name) against (CONCAT(?,'*') IN BOOLEAN MODE)
2. On a JSF page, drag ExecuteWithParams operation from data control onto the JSF page. If I have defined only one bind variable name, only one input field is displayed (and one field label that I defined for that bind variable), but I need two input fields - one for each bind position variable. How do I set this up?
Back-end Database is MySQL 5.0.1 which is why I am using binding stye JDBC positional.
Thanks, Tom

Answer 1

I did some more testing and the problem is that the queries work with one bind position variable but not with two. I created two simple view objects off of the same entity object to test:
#1 - ViewObject with one bind position variable - where clause: where id > ?
#2 - ViewObject with two bind position variables - where clause: where id > ? and id < ?
I created two separate .jspx pages, view1.jspx (one input field) and view2.jspx (two input fields), for each view object by dragging ExecuteWithParams operation onto the JSF page.
The .jspx page with one input field works (returns result sets.) The view2.jspx page with two input fields does not work - the query does not return any result sets (no errors produced, it just does not return any rows) - I've tested my query outside of jdeveloper and it works fine. I also tried switching my inputs to make sure I did not have an illogical query (i.e., id >100 and id< 1).
Is there anything different / extra I need to do to use two bind position variables?
I'm STUCK HERE.
Everything in this simple test was identical except for using 2 input variables versus 1.
Technology stack is: jdeveloper 10.1.3, jsf/ADF BC, mySQL 5.01
Since I now understand what the problem is better, I'm going to re-post this as a new topic that more appropriately describes the problem, "Queries not working with multiple bind position variables?"
