Answer 1

you should try the following :
MOST IMPORTANT TO CONSIDER, IS TO SET THE AUTOCOMMIT TO FALSE, otherwise MariaDB will refuse not automatic transaction management.
import java.sql.*;
public class App {
public static void main(String[] argv) {
try (Connection conn = DriverManager.getConnection("jdbc:mariadb://192.0.2.1:3306?user=db_user&password=db_user_password")) {
conn.setAutoCommit(false);
try {
try (PreparedStatement prep = conn.prepareStatement("INSERT INTO test.accounts(first_name, last_name, email, amount) VALUES (?, ?, ?, ?)")) {
prep.setString(1, "John");
prep.setString(2, "Smith");
prep.setString(3, "john.smith#example.com");
prep.setDouble(4, 900.00);
prep.executeQuery();
}
try (PreparedStatement prep = conn.prepareStatement("UPDATE test.accounts SET amount = ? WHERE email = ?")) {
prep.setDouble(1, 1000.00);
prep.setString(2, "john.smith#example.com");
prep.executeQuery();
}
conn.commit();
} catch (SQLException e) {
e.printStackTrace();
conn.rollback();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
