Hopefully, someone can use this information. Please consider me still a bloody beginner in mysql, php and Javascript!
I have a "Print Record" button on my edit form, which runs a report nuPrintPDF('001') on the click event.
I had the problem that for some records the report looked fine, while for others it was empty (when not all db fields had a value). I first thought that the problem was in the generation of the temporary table or my php version (php 5.3.27). I changed some parameters in the .htaccess file as suggested here:

But I found out that the error was in my sql query, where I had used INNER JOIN for a number of tables, like in the Edit form.
When changing this to LEFT JOIN it worked, because the right data gets selected.
Liked this illustration from http://stackoverflow.com/questions/5706437/whats-the-difference-between-inner-join-left-join-right-join-and-full-join:
