當Basex <tourism>
{
for $hotel in doc("tourism.xml")/tourism/hotel
let $r:=$hotel/room
let $g:=doc("tourism.xml")/tourism/guest
where $g/@name="Udo Lindenberg" and $g/customer/@hot
我想在BaseX中執行XQuery後打印QueryInfo。 以下是我的XQuery declare namespace db ='http://basex.org/modules/db';
declare option db:queryinfo 'true';
for $i in 1 to 1 return db:open('testDB')/*
如何將我的程序打印QueryInfo?
