 * Hi, don’t know if this is the right category, anyway
 * i couldn’t find these informations, hope someone can help.
 * 1. Where is the documentation for the query functions? I’d like to use wordpress
   funcs instead of mysql_query but the only info i’ve found are about ordering 
   a query.
    I need to use JOIN and IN or equivalent.
 * Is there an object i need to use to perform queryes?
    How do i get the table 
   prefix in case i have to make the queryes my self?
 * 2. the add_query_arg function doesn’t work with permalink
    what’s the function
   i need to use to create relative links to the same site in a plugin so that they’ll
   work as when using permalink as when don’t
 * Thanks for your help

 * 1. Could you use the [template tag](http://codex.wordpress.org/Template_Tags),
   [get_posts()](http://codex.wordpress.org/Template_Tags/get_posts)? If not see
   [wpdb](http://codex.wordpress.org/wpdb).
 * 2. I’m just guessing here, that you might need set_query_var, but look at a plugin
   such as [http://wordpress.org/extend/plugins/tdo-tag-fixes/](http://wordpress.org/extend/plugins/tdo-tag-fixes/)
   for some better ideas.
