"root", "root");
assert databaseMetadata != null;
System.out.println(databaseMetadata.getDatabaseProductName());
System.out.println(databaseMetadata.getDatabaseProductVersion());
System.out.println(databaseMetadata.getCatalogs());
System.out.println(databaseMetadata.getSchemas("renfeid"));
System.out.println(databaseMetadata.getTables("renfeid", null));
