Question

this is the code

    PreparedStatement res1 = null;
    String insertUser = "INSERT INTO users (uid,firstname,lastname,score) VALUES (" + 
                                            this.getFbUid() + "," + 
                                            this.getFbFirstName() + "," + 
                                            this.getFbLastName() + ",0)";
    System.out.println(insertUser);
    try
    {
        res1 = connection.prepareStatement(insertUser);
        res1.executeUpdate();
        System.out.println("executed query to db with the message" + res1);
    }
    catch(SQLException e)
    {
        System.out.println("setUserInDb: " +e.getMessage());
        System.out.println("error num: " +e.getErrorCode());
    }`

I’m getting error code 1054:

Unknown column ‘Alon’ in ‘field list’ when trying to insert the line “INSERT INTO users (uid,firstname,lastname,score) VALUES (123456,Alon,xyz,0)

In the db I have table users with varchar columns uid, firstname, lastname, and score.
What am I doing wrong?

Answer 1

Alon seems or type varchar should be under '

Use Prepared statement rather
