Parquet ODBC Driver

The Parquet ODBC Driver is a powerful tool that allows you to connect with live data from Parquet, directly from any applications that support ODBC connectivity.

Access Parquet data like you would a database - read, write, and update Parquet ParquetData, etc. through a standard ODBC Driver interface.



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

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

Connect to Parquet as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Connect to your local Parquet file(s) by setting the URI connection property to the location of the Parquet file.

Create a Profile for the ODBC Driver for Parquet

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

  1. In PowerBuilder, click Tools -> Database Painter.
  2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
  3. On the Connection tab, enter a name for the profile and select the Parquet DSN in the Data Source menu.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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

SQLCA.DBMS = "ODBC" SQLCA.DBParm = "ConnectString='DSN=CData Parquet Source'" CONNECT USING SQLCA; dw_sampletable_1.SetTransObject(SQLCA); dw_sampletable_1.Retrieve();
