Dude the new versions are completely different from older ones, I recommend you to update to R39 but still use mysql_query for compatibility, you must have to remake the whole structure to use tquery or pquery, so it's most recommended for starting to update your system, only add a handler in each mysql_query and deal with cache functions. You also will lose a lot of functions that we're supported in R5 but aren't anymore in R39. Take a read on the R33+ Wiki page.
