A [[Options|local database option]] can also be assigned locally via a pragma. Examples: * Whitespace chopping is disabled for a particular document (see {{Option|CHOP}}):
<pre class="brush:xquery">
(# db:chop false #) { doc('doc.xml') }
</pre>
* {{Version|9.0}}: Enforce index rewriting if database name is not static (see [[Indexes#Enforce Rewritings|Enforce Rewritings]] for more examples):
<pre class="brush:xquery">
(# db:enforceindex #) {
for $db in ('persons1', 'persons2', 'persons3')
return db:open($db)//name[text() = 'John']
}
</pre>
