Establishing a Connection

CData JDBC Driver for Query Federation 2019 - Build 19.0.7409

Creating a JDBC Data Source

You can create a JDBC data source to connect from your Java application. Creating a JDBC data source based on the CData JDBC Driver for Query Federation 2019 consists of three basic steps:

  • Add the driver JAR file to the classpath. The JAR file is located in the lib subfolder of the installation directory. Note that the .lic file must be located in the same folder as the JAR file.
  • Provide the driver class. For example:
  • Provide the JDBC URL. For example:

    The second format above can be used whenever there is a conflict in your application between drivers using the same URL format to ensure you are using the CData driver. The URL must start with either "jdbc:queryfederation:" or "jdbc:cdata:queryfederation:" and can include any of the connection properties in name-value pairs separated with semicolons.

Connecting to a Configuration File

Set the following properties to connect to your configuration file:

  • DatabaseConfiguration: Set this to a filepath pointing to your JSON-formatted schema definition file.
  • DefaultSchema: Set this to a schema (from your schema definition file) which will be used when the schema is not provided in any given query.
    For example, if you want to use TableName instead of MySchema.TableName in your query, set this property to MySchema.
