Hi,
Using restxq, do all queries have to begin with
db:open('web_app_db')//myquery/here , or can the database be declared? Or set as default somewhere?
Thanks,
Colin

Hi Colin,
we use db:open all over the place.
(: ----------------------------------------------------- :)
module namespace _ = 'com.gmail.colinmcenearney.db';
declare namespace restxq = "http://exquery.org/ns/restxq";
(: Database name used throughout the application. :)
declare variable $_:MY-DB := '_catalog';
(:~ Show users page. :)
declare
%restxq:path("/show-users")
%output:method("html")
function _:show-users()
{
<div> {
serialize(db:open($_:MY-DB)//user/@id)
} </div>
};
(: ----------------------------------------------------- :)Database name declarations often go to a constants.xqm.
Cheers,
Alex

Thanks Alex!
Good to know you use that construct a lot, and that it's not a bad practice for any reason
