To update data in an Access database using Java, you can use the JDBC-ODBC Bridge driver. However, please note that the JDBC-ODBC Bridge driver has been deprecated since Java 8 and is not recommended for use in production environments. It is recommended to use a dedicated JDBC driver provided by the database vendor for better performance and stability.
That being said, here’s an example using the JDBC-ODBC Bridge driver to update data in an Access database:
import java.sql.*; public class AccessDBDataUpdater { public static void main(String[] args) { // Database URL String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=/path/to/your/access_database.accdb"; // SQL query String query = "UPDATE your_table SET email = ? WHERE name = ?"; try { // Register JDBC driver Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); // Open a connection Connection conn = DriverManager.getConnection(url); // Create a prepared statement PreparedStatement stmt = conn.prepareStatement(query); // Set parameter values stmt.setString(1, "[email protected]"); stmt.setString(2, "John Doe"); // Execute the query int rowsAffected = stmt.executeUpdate(); // Process the result System.out.println(rowsAffected + " row(s) updated successfully."); // Close the resources stmt.close(); conn.close(); } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (SQLException e) { e.printStackTrace(); } } }
Replace /path/to/your/access_database.accdb with the actual path to your Access database file.
Keep in mind that the JDBC-ODBC Bridge driver might not be available in all Java environments, and its usage is discouraged in favor of native drivers provided by the database vendors.
