Error when running if function on mysql results

I'm trying to set permissions in a MySQL table, But i get the error:

Warning: mysqli::query() expects parameter 1 to be string, object given in 
/public/sites/http://ift.tt/2usQbPv on line 656

Catchable fatal error: Object of class mysqli_result could not be converted 
to string in /public/sites/http://ift.tt/2usQbPv on line 679

Does anyone has i fix for this, I've tried a lot of things but nothing worked

                    $sqlDataPermissies = mysqli_fetch_assoc($PermissiesUitlezen);

                if ($conn->query($PermissiesUitlezen) === TRUE) {
