Data Layer Query
An universal chainable data query interface object.
To create a Query, call the query(array) or query(url, queryOptions) utility function, depending on the type of storage you access. The Query enables you to execute several methods in a single statement, as it supports method chaining.
var processedArray = DevExpress.data.query(inputArray) .filter([ [ "value", ">=", 10 ], "and", [ "value", "<=", 90 ]]) .sortBy("lastName") .thenBy("firstName") .select("lastName", "firstName", "value") .toArray();
For more information on the Query concept, refer to the Data Layer article.
This section describes the methods used to access the data associated with the Query.
