UserDefinedFunctions class

container: Container

Property Value

Create a UserDefinedFunction.

Azure Cosmos DB supports JavaScript UDFs which can be used inside queries, stored procedures and triggers.

For additional details, refer to the server-side JavaScript API documentation.

Example

import { CosmosClient, UserDefinedFunctionDefinition } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });
const { database } = await client.databases.createIfNotExists({ id: "Test Database" });
const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

const udfDefinition: UserDefinedFunctionDefinition = {
  id: "sample udf",
  body: "function () { const x = 10; }",
};

const { resource: udf } = await container.scripts.userDefinedFunctions.create(udfDefinition);

function create(body: UserDefinedFunctionDefinition, options?: RequestOptions): Promise<UserDefinedFunctionResponse>

Parameters

Returns

Query all User Defined Functions.

function query(query: SqlQuerySpec, options?: FeedOptions): QueryIterator<any>

Parameters

Returns

Query all User Defined Functions.

Example

import { CosmosClient } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });
const { database } = await client.databases.createIfNotExists({ id: "Test Database" });
const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

const querySpec = {
  query: "SELECT * FROM root r WHERE r.id=@id",
  parameters: [
    {
      name: "@id",
      value: "<udf-id>",
    },
  ],
};
const { resources: results } = await container.scripts.userDefinedFunctions
  .query(querySpec)
  .fetchAll();

function query<T>(query: SqlQuerySpec, options?: FeedOptions): QueryIterator<T>

Parameters

Returns

Read all User Defined Functions.

Example

Read all User Defined Functions to array.

import { CosmosClient } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });

const { database } = await client.databases.createIfNotExists({ id: "Test Database" });

const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

const { resources: udfList } = await container.scripts.userDefinedFunctions.readAll().fetchAll();

function readAll(options?: FeedOptions): QueryIterator<UserDefinedFunctionDefinition & Resource>

Parameters

Returns
