[basex-talk] how to specify a database in a.xq FLOWR query?

how do I specify a database for a .xq file to use?

a simple FLOWR:

thufir@dur:~/basex/w3$ thufir@dur:~/basex/w3$ basex titles.xq [warning] /usr/bin/basex: Unable to locate /usr/share/java/jing.jar in /usr/share/java <title lang="en">Learning XML</title> <title lang="en">XQuery Kick Start</title>thufir@dur:~/basex/w3$ thufir@dur:~/basex/w3$ thufir@dur:~/basex/w3$ cat titles.xq for $x in doc("books.xml")/bookstore/book where $x/price>30 order by $x/title return $x/title thufir@dur:~/basex/w3$

(from w3schools)

thanks,
