Connect to HarperDB データ from PowerBuilder

This article demonstrates how to use the CData ODBC Driver for HarperDB to connect to HarperDB データ and execute queries in PowerBuilder.




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

Create a Profile for the ODBC Driver for HarperDB

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

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

    See the help documentation for a guide to creating a HarperDB 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 HarperDB 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 HarperDB データ 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 HarperDB データ into a DataWindow. You can add the following code to the open method:

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