HSQLDB Connection using Java

The advantage of HSQLDB is that it supports SQL-92, 2008, 2011 standards and the small DB engine fastens the process. Also it offers In-memory and disk-based tables.

Tech Stack: Java 8 ( version 6 or more will also work)
HSQLDB jar (HSQLDB 2.4.0 jar supports Java 8)

Setting up HSQLDB in local:

  • Download the hsqldb-2.4.0 zip file and extract the same. The lib folder should contain the hsqldb.jar.
  • Inside bin folder runManagerSwing.bat is the file which opens the DatabaseManagerSwing class and using GUI the applet front end will open.
  • Create a file named server.properties inside the folder and update the file with below values:

server.database.0 = file:hsqldb/demodb

server.dbname.0 = testdb

As by default no DB is created, above content will create a database inside hsqldb folder named as demodb with database name testdb.

  • Command to run the above DB (using cmd) is:

java -classpath lib/hsqldb.jar org.hsqldb.server.Server –database.0 file:hsqldb/demodb –dbname.0 testdb

  • Once the above command runs, the DB will be up and running and run runManagerSwing.bat file. Provide the details as below:dbconn



  • Details of db.properties file:prop

Sample program:

package com.test.hsqldb;
import java.io.FileInputStream;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class DbConnection {
       public static void main(String[] args) throws Exception{
               Connection con = null;
               Statement stmt = null;
               ResultSet result = null;
               Properties prop = loadProperties();
               String driverClass = prop.getProperty(“HSQL.driverclass”);
               String hsqlURL = prop.getProperty(“HSQL.url”);
               String username = prop.getProperty(“HSQL.username”);
               String password = prop.getProperty(“HSQL.password”);
                      con = DriverManager.getConnection(hsqlURL, username, password);
                      stmt = con.createStatement();
                      /*result = stmt.executeUpdate(“CREATE TABLE tutorials_table “
                                     + “(id INT NOT NULL, title VARCHAR(50) NOT NULL, author VARCHAR(20) NOT NULL, “
                                     + “submission_date DATE,PRIMARY KEY (id));”);*/
                      /*result = stmt.executeUpdate(“DROP TABLE tutorials_table”);*/
                      /*result = stmt.executeUpdate(“INSERT INTO tutorials_table VALUES (102,’Learn HSQL’, ‘Davy Jones‘, NOW())”);*/
                      result = stmt.executeQuery(“SELECT id, title, author FROM tutorials_table”);
                   System.out.println(result.getInt(“id”)+” || “+
                      result.getString(“title”)+” || “+
               }catch(Exception e){
       private static Properties loadProperties() throws Exception {
               Properties prop = new Properties();
               InputStream in = new FileInputStream(“db.properties”);
               return prop;
  • If we replace the hsqldb file and server.properties which is created in my system in some other’s system. Then same db with values will be reflected in the other system.
