MySQL database technology can be combined with other technologies, such as Java, Python, PHP, etc. Mastering MySQL database technology can enable you to better collaborate with other developers and improve the work efficiency of the entire team. The following is a simple Java code example:

import java.sql.*;

public class Main {
  public static void main(String[] args) {
    try {
      Class.forName("com.mysql.jdbc.Driver");
      Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");
      Statement stmt = conn.createStatement();
      String sql = "SELECT * FROM employees";
      ResultSet rs = stmt.executeQuery(sql);
      while (rs.next()) {
        System.out.println(rs.getString("name"));
      }
      rs.close();
      stmt.close();
      conn.close();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}
