Javier,
This is not a DBI issue. What does the query do in SQL*Plus? Is the relationship between the tables mandatory, or should you be using an outer or inner join?

AND I.idEntry = E.idEntry The query runs fine but I get no information back from it. What could be wrong? I ran the same query (replacing the placeholder with the value) on the database and it ran fine and returned information.
