         db.execSQL("create table booking(serviceID INTEGER primary key, name TEXT,email TEXT,phone TEXT )");    
    }

    @Override

        SQLiteDatabase db = this.getWritableDatabase();  
        ContentValues values = new ContentValues();

        // on below line we are passing all values
        // along with its key and value pair.    
        values.put("serviceID", serviceID);

        values.put("notes", notes);
        values.put("phone", phone);
        values.put("email", email);    
        // after adding all values we are passing
        // content values to our table.
        db.insert("booking", null, values);    
        // at last we are closing our
        // database after adding database.            
    }
   
    public Boolean checkusername(String username){
        SQLiteDatabase db = this.getWritableDatabase();
        Cursor cursor = db.rawQuery("select * from users where username = ?", new String[] {username});
