I am new to MySQL and thinking to use MySQL for my new Java Project which creates a database on the local client machine and uses it to perform all data operations. But before proceeding with MySQL I'm in a bit of doubt that I have MySQL server installed so it is working fine on my machine but what if I give this software to an end user which do not have it installed or with some other username and password. Like I have following code for creating a database, it will most probably not work on any target client machine. I know its bit of stupid question but i'm unable to think of a solution for it.

public class CreateDatabase {
  public static void main(String[] args) {
    Connection connection = null;
    Statement statement = null;
    try {
      Class.forName("org.gjt.mm.mysql.Driver").newInstance();
      String url = "jdbc:mysql://localhost/mysql";
      
      connection = DriverManager.getConnection(url, "root", "root");

      statement = connection.createStatement();
      String dbSQL = "CREATE DATABASE mynewdb";
      statement.executeUpdate(dbSQL);
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
      if (statement != null) {
        try {
          statement.close();
        } catch (SQLException e) {
        } // nothing we can do
      }
      if (connection != null) {
        try {
          connection.close();
        } catch (SQLException e) {
        } // nothing we can do
      }
    }
  }

}

A quick diagnosis and practical options

The posted code assumes a MySQL server is present on localhost and that a privileged account (root/root) is available — a fragile assumption for redistributed desktop software. As pointed out, the simplest way to avoid requiring a separate DB install is to use an embedded database; later confirmed JavaDB met the OP’s needs. Embedded databases keep the data as files shipped with the app and remove the need to install or configure a server on each client.

How to proceed (practical pattern)

  • Choose an embedded engine when the app is single-user or has light local concurrency (Derby/JavaDB, H2, HSQLDB, or SQLite via a JDBC wrapper). Bundle the JDBC driver JARs with the application and create the database in a per-user application folder (e.g., %APPDATA% on Windows or ~/.appname on Unix).
  • Minimal embedded-connection example (Derby/JavaDB):
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
Connection conn = DriverManager.getConnection("jdbc:derby:myappDB;create=true");

This auto-creates a local database file; the driver JAR must be included in the app distribution.

When an embedded DB is not appropriate

  • For multi-user or networked applications, run a central DB server (MySQL/MariaDB/Postgres) on a hosted machine and connect clients over the network. This requires server administration and proper credentials — do not hard-code root-level credentials in shipped software.
  • If a local server is required but installation must be automated, bundle and install a server as part of the app installer or use an embeddable server wrapper that launches a private server instance. That increases complexity (service permissions, ports, upgrades) but preserves server-level features.

Testing, security, and packaging checklist

  • Test on a clean OS image.
  • Store DB files in a writable, per-user directory.
  • Avoid embedding administrative passwords; create limited-scope DB users when possible.
  • Provide migration/export tools (SQL dump or export/import) for future upgrades.

This guidance complements ’s suggestion and ’s follow-up: pick an approach based on concurrency and deployment constraints, bundle required driver binaries, and test a clean install path.

Try using H2 or JavaDB instead. Both are embedded databases that do not need to be separately installed.

Wow I never knew that.

Thanks, javadb is working great for my requirements.
