Java DB (Derby) Network Server and JDBC Driver Info
This section describes how to get some basic info about Java DB (Derby) and JDBC driver through the JDBC DatabaseMetaData object.
If you want to know the Java DB database name and version, or the JDBC driver name and version, you can get them through the DatabaseMetaData object as shown in the following sample program:
/* DerbyDatabaseInfo.java * Copyright (c) HerongYang.com. All Rights Reserved. */ import java.sql.*; public class DerbyDatabaseInfo { public static void main(String [] args) { Connection con = null; try { con = DriverManager.getConnection("jdbc:derby://localhost/TestDB"); // Database and driver info DatabaseMetaData meta = con.getMetaData(); System.out.println("Server name: " + meta.getDatabaseProductName()); System.out.println("Server version: " + meta.getDatabaseProductVersion()); System.out.println("Driver name: " + meta.getDriverName()); System.out.println("Driver version: " + meta.getDriverVersion()); System.out.println("JDBC major version: " + meta.getJDBCMajorVersion()); System.out.println("JDBC minor version: " + meta.getJDBCMinorVersion()); con.close(); } catch (Exception e) { System.err.println("Exception: "+e.getMessage()); } } }
If you are using Java 9 or higher version, you compile and run your Java program in one command:
(on Windows) herong> java -cp %DERBY_HOME%\lib\derbyclient.jar SomeClass.java (on Linux or macOS) herong> java -cp $DERBY_HOME/lib/derbyclient.jar SomeClass.java
So let's try it here to run the sample program using one the commands below depending which computer platform you are using:
herong> java -cp %DERBY_HOME%\lib\derbyclient.jar DerbyDatabaseInfo.java herong> java -cp $DERBY_HOME/lib/derbyclient.jar DerbyDatabaseInfo.java Server name: Apache Derby Server version: 10.15.1.3 - (1853019) Driver name: Apache Derby Network Client JDBC Driver Driver version: 10.15.1.3 - (1853019) JDBC major version: 4 JDBC minor version: 2
The output confirms that Derby JDBC driver 10.15 supports JDBC 4.2
