I am doing a Java project to allow users to either log in as an admin or user based on what they selected from their account creation. I managed to do a code to check if their username and password were correct in my login page of the application by checking if those values are present in the database, however, I want the user to login as either an admin or user but I don’t know how to do that. Im thinking if I can read what they selected as (either user or admin) from their account creation in the database (refer below for picture of database columns), then I am able to do an if statement based on that. For example if(usertype == ‘admin’){ // then go to admin page} But usertype is a column in the database which I don’t know how to read.I have my code below as well which is function that activates whenever the login button is pressed.If you know of a solution, let me know thank you.
private void LoginButtonActionPerformed(java.awt.event.ActionEvent evt) {
Connection con;
PreparedStatement pst;
ResultSet rs;
try{
String query = "SELECT * FROM `accounts` WHERE username=? and password=?"; // and usertype=?
con = DriverManager.getConnection("jdbc:mysql://localhost/restock", "root", "password");
pst = con.prepareStatement(query);
pst.setString(1, txtUsername.getText());
pst.setString(2, txtPassword.getText());
rs = pst.executeQuery();
if(rs.next()){
JOptionPane.showMessageDialog(this, "Login is successful as admin");
mainpage admin = new mainpage();
admin.setVisible(true);
dispose();
}
else{
JOptionPane.showMessageDialog(this, "Incorrect username or password");
/*usermainpage user = new usermainpage();
user.setVisible(true);
dispose();*/
}
} catch(Exception ex){
JOptionPane.showMessageDialog(this, ex.getMessage());
}
}
This is a picture of the columns that are in my database

Answer
Since you’re doing a SELECT *, you should be able to access the usertype in your java code with something like
if(rs.next()){
String userType = rs.getString("usertype");
if(userType.equals("admin")){
// your admin code here
}else{
// your user code here
}
}
