  Why?  Could you *please* try reading the documentation that comes with
FreeRADIUS?

  I mean, go to http://freeradius.org, and click on either the "doc"
link, or the "wiki" link.  You will see a *lot* of documentation.

  Type "sql" into the search box on the Wiki, and you'll get lots of
documentation about the SQL module.

  Or... read the file doc/rlm_sql, which comes with the server.

  Mostly, yes.

  No.

  Why would you write any C code?  It isn't necessary.
