Android SQLite语法错误

它老说我SQL语法有问题，可是我对照网上写的折腾半天也没发现错在哪里啊。
新手求赐教，谢谢！
附上代码
@Override

public void onCreate(SQLiteDatabase db) {
    // TODO Auto-generated method stub
    db.execSQL("CREAT TABLE IF NOT EXISTS notepadtable(id int,"
            + "title varchar(20),"
            + "content varchar)");
    System.out.println("creat database");
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // TODO Auto-generated method stub
    db.execSQL("DROP TABLE IF EXISTS"+"notepadtable");
    onCreate(db);
}

错误报告看不了就看这个：
12-18 01:14:04.340: E/SQLiteLog(4222): (1) near "EXISTSnotepadtable": syntax error
