develop Sql query for Typo3 database

We are using Typo3 backend for the content of a flash side. We need an adjustment in one class to be able to get the output for content that is a reference (lilnked by templavoila to an element on another page) in the backend. The standard content is stored in the table tt_content, the references are stored in the tabel pages / tx_templavoila_flex. The script we have now only gets the content from the tt_content table. We need to overwork it, so that it will as well get put the content for the references (linked) elements. Attached you find the class that now gets back the selected elements form table tt_content. We need to add the output for the refereced (linked) elements.
