BatchQuery class

Level: advanced

Batch queries are used to minimize requests to DataServise, which improves application performance. Packet query is a collection that contains a custom set of DataService requests. The query data is transferred to DataService via HTTP, with the help of POST by the URL.

Structure of batch query

// URL format of the batch POST query to DataService.
http(s)://[Creatio application address]/[Configuration number]/dataservice/[Data fromat]/reply/BatchQuery

Example the batch query

// URL example of the batch POST query to DataService.
http(s)://example.creatio.com/0/dataservice/json/reply/BatchQuery

The data that comprises a batch query can be passed in different formats. One of the more convenient formats is JSON.

Structure of a batch query in JSON format

{
    "items": [
        {
            "__type": "[Full qualified name of the query type]",
            //One-time query contents.
            ...
        },
        // Other one-time queries.
        ...
    ]
}

To generate the contents of one-time queries that comprise a batch query, use the following data constants: InsertQuery, SelectQuery, UpdateQuery and DeleteQuery.
