title: Cross database query engine for Oracle database using Qt
body: <p>I am developing an Qt application where I want to query data from tables in 2 different databases at once. I am using Oracle as the database but my employer wants me to achieve this without making a database link between the 2 databases. So I thought of developing a cross database query engine using Qt sql module objects. But it should not be as complex as an sql parser. I just want query data from tables in two databases and display them in 1 view and do these queries using a common interface. But according to my knowledge Qt sql modules can be used to query from only 1 database. If there is anyone who has done this kind of programming before or someone who has an idea about this, your suggestions are much appreciated. Thank you very much.</p>
