I want to use in this class
import java.sql.Connection;
import java.sql.DriverManager;

import java.sql.Statement;
import javax.swing.JOptionPane;
public abstract class ConnectionDB
{
public static void main(String[] args)
{
SpringSample sp = new SpringSample();
try {
insertRecordIntoDbUserTable();
selectfromdb();
}
catch (SQLException e)
{
System.out.println(e.getMessage());
}
}
private static void insertRecordIntoDbUserTable() throws SQLException
{
Connection con = null;
Statement statement = null;
String insertTableSQL = "INSERT INTO LoginDetails" + "(Username, Password) " + "VALUES" + "('null2','tf_Lname')";
try
{
con = DBConnectionstring();
statement = con.createStatement();
System.out.println(insertTableSQL);
statement.executeUpdate(insertTableSQL);
JOptionPane.showMessageDialog(null,"Your Data has been Inserted","Data Inserted",JOptionPane.WARNING_MESSAGE);
}
catch (SQLException e)
{
System.out.println(e.getMessage());
}
finally
{
if (statement != null)
{
statement.close();
JOptionPane.showMessageDialog(null,"Statement is closed","Statement",JOptionPane.WARNING_MESSAGE);
}
if (con != null)
{
con.close();
JOptionPane.showMessageDialog(null,"Connection is closed!","Connection",JOptionPane.WARNING_MESSAGE);
}
}
}
private static void selectfromdb() throws SQLException
{
Statement stmt = DBConnectionstring().createStatement();
ResultSet rs = stmt.executeQuery("SELECT Username,Password FROM LoginDetails");
while (rs.next())
{
String lastName = rs.getString("Username");
String Pass = rs.getString("Password");
System.out.println(lastName + "" + Pass + "\n");
}
}
static Connection DBConnectionstring()
{
Connection con = null;
String conUrl = "jdbc:sqlserver://localhost:1433; databaseName=paytest; user=PC; password=; integratedSecurity=true;";
try
{
con = DriverManager.getConnection(conUrl);
JOptionPane.showMessageDialog(null,"Connection is open!","Connection",JOptionPane.WARNING_MESSAGE);
}
catch (SQLException e)
{
e.printStackTrace();
}
return con;
}
}
How can I do that?
