解説

When specified, the CData JDBC Driver for Apache Impala will issue a 'USE [Database]' command upon connecting to Impala. This will be the database schema used when executing queries that do not have a schema explicitly specified.

To execute queries on other schemas, the schema can be explicitly specified in the statement.

When Database is not set, the 'default' database schema will be used (no 'USE' statement is issued to Impala in this case).
