Motivation

The default value of GetObjectsPatternsRequireLowerCase of DatabricksConnection is false (inherit from SparkConnection, see here), so when it is called with table pattern in uppercase as below, it does not return all the tables start with test and fails some test cases DriverTest:GetObjectsTablesTest (when tableNamePattern is uppercase)

Connection.GetObjects(
                    depth: AdbcConnection.GetObjectsDepth.Tables,
                    catalogPattern = "catalog1",
                    dbSchemaPattern = "default",
                    tableNamePattern = "TEST%");

Changes

• Override GetObjectsPatternsRequireLowerCase to true in DatabricksConnection
