Can I declare a global variable in xquery in Marklogic Server?

Question

I want a global variable which I can use in my different .xqy pages. Can I declare such a variable in xquery in Marklogic Server ?

Answer 1

You can declare a variable in any module. For instance, it is config.xqy.

declare variable $PRECISION as xs:integer := 4;

For using this variable you need to import this module in your work module.

import module namespace config = "http://your-namespace" at "config.xqy";

And refer to this variable:

$config:PRECISION

Answer 2

If your application is running on a single E-node, you can use server fields , which are sort of designed for this use case as well.
