The first parameter in mysql_query for R33+ is the connection handle (which is returned by mysql_connect) and the query string is the second one (in your case var).

Also it's not exactly the same like updating and it will work. You need to modify it: https://sampwiki.blast.hk/wiki/MySQL/R33#mysql_query

However, threaded queries are always better and faster to use.
