Oracle Connector

To configure the Oracle connector, create a catalog properties file in named, for example, oracle.properties, to mount the Oracle connector as the oracle catalog. Create the file with the following contents, replacing the connection properties as appropriate for your setup:

The connection-url defines the connection information and parameters to pass to the JDBC driver. The Oracle connector uses the Oracle JDBC Thin driver, and the syntax of the URL may be different depending on your Oracle configuration. For example, the connection URL is different if you are connecting to an Oracle SID or an Oracle service name. See the Oracle Database JDBC driver documentation for more information.

The connection-user and connection-password are typically required and determine the user credentials for the connection, often a service user.

You can have as many catalogs as you need, so if you have additional Oracle servers, simply add another properties file to with a different name (making sure it ends in .properties). For example, if you name the property file sales.properties, Presto will create a catalog named sales using the configured connector.

If you have a Oracle database named web, you can view the tables in this database by running :

You can see a list of the columns in the clicks table in the web database using either of the following:

Finally, you can access the clicks table in the web database:

If you used a different name for your catalog properties file, use that catalog name instead of oracle in the above examples.
