Queries not working with multiple bind position variables?

Question

still need help here - can anyone provide any direction?
(note: this is a follow-up from prior topic, " How to use JDBC Positional Binding Style & ExecuteWithParams?")
I created two simple view objects off of the same entity
object to perform this 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?
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

Answer 1

Using the where clause: "where id > ? and id < ?” for the 2 input variables, I get the same result - no row results returned (though query works outside the browser.)
Interestingly, I modified the where clause to “where between ? and ?”, and then used values of ‘1’ and ‘100’ to test. Using the BC4J tester, the query gave back a single row with id = 100 (should have brought back 100 rows because there are 100 records with id’s 1-100.) So I got it to return something, but not the right results. This makes me believe that a different query is being sent to MySQL other than what I'm expecting from what is shown in the SQL Statement of the View Object..
Is there anyway to view what SQL statement is actually being sent to the database using the BC4J tester? Also, could this be an issue related to the mySQL connector drivers and JDeveloper? I’m using mysql-connector-java=3.1.11-bin.jar (10/10/2005)? First though, if I could see what query is actually being sent, this may help me to debug and figure out the problem.
