Hello!
I am trying to add new data into a database.
What is the mistake in my code?
I got the error message such as "general error".

import java.awt.*; import java.awt.event.*; import java.sql.*; import javax.swing.*; public class AddRecord implements ActionListener{ private ScrollingPanel fields; private JTextArea output; private Connection connection; public AddRecord(Connection c, ScrollingPanel f, JTextArea o) { connection =c; fields=f; output=o; } public void actionPerformed( ActionEvent e) { try { Statement statement=connection.createStatement(); if( !fields.last.getText().equals("")&& !fields.first.getText().equals("")){ String query="INSERT INTO addresses ("+ "firstname, lastname, address, city,"+ "stateorprovince, postalcode, country,"+ "emailaddress, homephone, faxnumber"+ ") VALUES ('"+ fields.first.getText()+"','"+ fields.last.getText()+"','"+ fields.address.getText()+"','"+ fields.city.getText()+"','"+ fields.state.getText()+"','"+ fields.zip.getText()+"','"+ fields.country.getText()+"','"+ fields.email.getText()+"','"+ fields.home.getText()+"','"+ fields.fax.getText()+"')"; output.append("\nSending query:"+ connection.nativeSQL(query)+"\n"); int result=statement.executeUpdate(query); if (result==1) output.append("\nInsertion successful\n"); else { output.append("\nInsertion failed\n"); fields.first.setText(""); fields.last.setText(""); fields.address.setText(""); fields.city.setText(""); fields.state.setText(""); fields.zip.setText(""); fields.country.setText(""); fields.email.setText(""); fields.home.setText(""); fields.fax.setText(""); } } else output.append("\nEnter at least first and "+ "last name then press Add\n"); statement.close(); } catch (SQLException sqlex){ sqlex.printStackTrace(); output.append(sqlex.toString()); } } }
Try using a preparedStatement rather than cobbling together a query statement like that.
