Return values for DatabaseMetaData Table 63: Return values for DatabaseMetaData methods (11 of 11) Method Description Returns supportsTableCorrelationNames() Are table correlation names supported? A JDBC-compliant driver always returns true. supportsTransactionIsolationLevel(in t) Does the database support the given transaction isolation level? supportsTransactions () Are transactions supported? If not, commit is a no-op and the isolation level is TRANSACTION_NONE. Example The following example is a code segment that illustrates calling methods of DatabaseMetadata: True True (for all four transaction levels) True supportsUnion() Is SQL UNION supported? True supportsUnionAll() Is SQL UNION ALL supported? usesLocalFilePerTable() Does the database use a file for each table? usesLocalFiles() Does the database store tables in a local file? True False False Connection con = DriverManager.getConnection ( url, prop); . . . // Get the DatabaseMetaData object and display // some information about the connection DatabaseMetaData dma = con.getMetaData (); o.println("\nConnected to " + dma.getURL()); o.println("Driver " + dma.getDriverName()); o.println("Version " + dma.getDriverVersion()); 283
