I'm not sure what you're asking then. The username is logged as "anonymous" because the user has typed in "anonymous". FreeRADIUS logs what the NAS and the client send.

If you don't accounting packets to contain "anonymous" you can:
 * reject their authentication.
 * configure your NAS to send something more meaningful

There's no secret SQL query - if the user sends "anonymous", and your NAS is configured to use that "anonymous" in accounting, then FreeRADIUS will log "anonymous", and any SQL query will return "anonymous".

If explain your problem further (e.g. why is correlating the Calling-Station-ID in accounting logs to the one in your auth log insufficient) people can probably help further - but you've given precious little information.
