Connect to Cosmos DB Data from PowerBuilder


This article demonstrates how to use the CData ODBC Driver for CosmosDB to connect to Cosmos DB data and execute queries in PowerBuilder.

The CData ODBC Driver for CosmosDB can be used from any platform or development technology that supports ODBC, including Sybase PowerBuilder. This article shows how to connect to Cosmos DB data and execute queries from the Database Painter and controls such as the DataWindow.

Create a Profile for the ODBC Driver for CosmosDB

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for CosmosDB. In the Database Painter, you can use wizards and the UI to work with Cosmos DB data.

  1. If you have not already done so, create an ODBC DSN for CosmosDB. The DSN contains the connection properties required to connect to Cosmos DB data. You can use the Microsoft ODBC Data Source Administrator to create and configure DSNs. This is the last step of installing the driver. Required connection properties are the following:
    • AccountEndpoint
    • AccountKey

    SQL API を使ってCosmos DB アカウントに接続するために必要な接続文字列を取得するには、Azure Portal にログインして「Azure Cosmos DB」を選択し、自分のアカウントを選択します。「Settings」セクションで、「Connection String」をクリックして次の値を設定します。

    • AccountEndpoint: 値は、Cosmos DB アカウントの「Keys」ブレードからのCosmos DB アカウントURL である必要があります。
    • AccountKey: Azure ポータルで、Cosmos DB サービスに移動してAzure Cosmos DB アカウントを選択します。リソースメニューから、 「Keys」ページに移動します。「PRIMARY KEY」値を見つけ、Token をこの値に設定します。
    See the help documentation for a guide to creating a Cosmos DB DSN.
  2. In PowerBuilder, click Tools -> Database Painter.
  3. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  4. On the Connection tab, enter a name for the profile and select the Cosmos DB DSN in the Data Source menu. The ODBC DSN, required to create the Database Profile. (Salesforce is shown.)
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.
Live data accessible from an editable grid. (Salesforce is shown.)

Using Cosmos DB Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve Cosmos DB data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Cosmos DB Source'" CONNECT USING SQLCA; dw_customers.SetTransObject(SQLCA); dw_customers.Retrieve();
