The result of applying the specified predicate is true for at least one of the entities resulting from the left hand property expression. Is equal to one of the values in the specified list Initially it was made for JavaScript, but many other languages have libraries to handle it as well. Whether of not to include the ‘inlineCount’ The JSON (JavaScript Object Notation) is a general format to represent values and objects. The number of items to skip before returning resultsĮach string must be a valid property path, optionally followed by either ‘asc’ or ‘desc’Įach string must be a valid property pathĬustom parameters to include in a query (equivalent to. For example, the breeze node/MySql/MariaDb/Postgres server has support for the ‘like’ and ‘nlike’ query operators which cannot be supported via the OData query syntax. When JSON data is stored in the database you can query it using path expressions that are somewhat analogous to XQuery. Especially insofar as virtually all server technologies have libraries for consuming json.Īn additional reason for this format is that it supports the concept of allowing for expanded query capabilities via the ability to add query operators that are tailored to a specific backend server technology. JSON is a notation for JavaScript values. On the server, the major reason for supporting this alternative format is that it is often easier to consume for those servers that are not already designed to understand OData. JSON QUERY JAVASCRIPT OFFLINEOn the client side, the reason for creating this format was to allow queries to be saved offline and recreated based on the serialized offline data. You cannot use it with a new operator or invoke the JSON object as a function. Description Unlike most global objects, JSON is not a constructor. a query created via the breeze fluent interface can still be sent to the server as a urlEncoded json query and vice versa, a query created with using the json format can still be used with the default OData ‘uriBuilder’. The JSON object contains methods for parsing JavaScript Object Notation ( JSON) and converting values to JSON. Note that the use of the json uri adapter is independent of the mechanism by which the query was created. Of course, this will only work if your server understands this format as opposed to the default OData query format.
