+String databaseId = "my-database";
+
+try (Connection connection =
+ DriverManager.getConnection(
+ String.format(
+ "jdbc:cloudspanner:/projects/%s/instances/%s/databases/%s",
+ projectId, instanceId, databaseId))) {
+ try (Statement statement = connection.createStatement()) {
+ try (ResultSet rs = statement.executeQuery("SELECT CURRENT_TIMESTAMP()")) {
+ while (rs.next()) {
+ System.out.printf(
+ "Connected to Cloud Spanner at [%s]%n", rs.getTimestamp(1).toString());
+ }
+ }
