Connect to Square Data from PowerBuilder

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

Connect to Square 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.

Square uses the OAuth authentication standard. To authenticate using OAuth, you will need to register an app with Square to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Additionally, you must specify the LocationId. You can retrieve the Ids for your Locations by querying the Locations table. Alternatively, you can set the LocationId in the search criteria of your query.

Create a Profile for the ODBC Driver for Square

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for Square. In the Database Painter, you can use wizards and the UI to work with Square 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 Square DSN in the Data Source menu.
4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

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