Connect to Snowflake Data from PowerBuilder via ODBC

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

Getting Started

---

Connect to Snowflake 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.

To connect to Snowflake:

1. Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
2. Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
3. Set Warehouse to the Snowflake warehouse.
4. (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
5. (Optional) Set Database and Schema to restrict the tables and views exposed.
6. (Optional) If MFA is enabled on your Snowflake account (via Duo Security), set MFACode to the passcode generated by your Duo authenticator app.

See the Getting Started guide in the CData driver documentation for more information.

Create a Profile for the ODBC Driver for Snowflake

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

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

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