Echo username from userid

[grey_goose]

PHP Code:

{vb:raw bbuserinfo.field163} 

I have a custom profile field, 163, that is the userid of a -different- account (users have multiple accounts).

How do i use that profile field's userid (#) to display the username of that referenced account in a template? The above doesn't work, and I've been looking around for a way to do it without calling a php query to the database.

The userfield table, which is where the data for the userfields is stored, has a userid field, but no username field. So, you would need to do a query to get the userid for the username you wish to get the field data.
