The examples below shows how to query the domain database.
Example
Find all customers
var results = $XmlRepository.Query('//Customer'); $Xml.InnerXml( 'Customer', results.join() );
Example
Find customer by id
var results = $XmlRepository.Query('//Customer[Id=$id]', { id : $Xml.Evaluate('CustomerId') }); $Xml.InnerXml( 'Customers', results.join() );
Example
Query Update
$XmlRepository.Query('for $customer in //Customer[Id=$id] return replace value of node $customer/Name with "Lady Gaga"', { id : $Xml.Evaluate('CustomerId') });
Example
Query Insert
$XmlRepository.Query('insert node (<Kaynak><Id>{$newId}</Id><Ad>{$newName}</Ad></Kaynak>) as last into /KVKEnvanter/Tanimlar/Kaynaklar', { newId: newId, newName: name.trim() });
Example
Query Delete
$XmlRepository.Query('let $nodeValue := fn:parse-xml-fragment($nodeValue)' + 'for $record in Relation[Id=$id]/RepHistory/RepHistoryRecord[InstanceId=$instanceId] return ' + '(delete node $record)', { id : relationId, instanceId : $Xml.Evaluate('SelectedHistory/Id'), nodeValue : $Xml.SelectSingle('.').InnerXml() });
Example
Querying process database
var results = $XmlRepository.Query('collection("49551ed3-6229-408a-aaaa-eb510463acad")//Customer[Id=$id]', { id : $Xml.Evaluate('CustomerId') }); $Xml.InnerXml( 'Customers', results[0].Evaluate('Id') );
Example
Querying process database var results = $XmlRepository.Query('collection("49551ed3-6229-408a-aaaa-eb510463acad")//Customer[Id=$id]', { id : $Xml.Evaluate('CustomerId') }); $Xml.InnerXml( 'Customers', results[0].Evaluate('Id') );
