Redis ODBC Driver

The Redis ODBC Driver is a powerful tool that allows you to connect with Redis high-performance data stores, directly from any applications that support ODBC connectivity.

Read, write, and update Redis data through a standard ODBC Driver interface.



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

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

Connect to Redis 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.

Set the following connection properties to connect to a Redis instance:

  • Server: Set this to the name or address of the server your Redis instance is running on. You can specify the port in Port.
  • Password: Set this to the password used to authenticate with a password-protected Redis instance , using the Redis AUTH command.

Set UseSSL to negotiate SSL/TLS encryption when you connect.

Create a Profile for the ODBC Driver for Redis

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

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

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