Create a Profile for the ODBC Driver for Couchbase

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

  1. If you have not already done so, create an ODBC DSN for Couchbase. The DSN contains the connection properties required to connect to Couchbase 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:
    • User
    • Password
    • Server

    ログインメソッドで接続するには、User、Password、およびServer を、アカウントのクレデンシャルと接続するサーバーのアドレスに設定します。

    See the help documentation for a guide to creating a Couchbase 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 Couchbase DSN in the Data Source menu.
  5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Couchbase 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 Couchbase data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Couchbase Source'" CONNECT USING SQLCA; dw_customer.SetTransObject(SQLCA); dw_customer.Retrieve();
