Android中的游标错误告诉我列不存在

错误发生在我的游标适配器参数中,设置“到”列,它告诉我此列“引用”不存在.

我已经尝试将to参数更改为KEY_QUOTE,甚至尝试更改实际数据库列的名称,但现在仍然很高兴.

我究竟做错了什么？

以下是此操作中使用的代码块.

>创建数据库表,引号
>填充此表
>查询报价
>打开数据库连接,创建游标(我收到实际错误,使用“from”参数)

1.

private static final String CREATE_QUOTE_TABLE = 

            "create table " + QUOTES_TABLE +
            " (_id integer primary key autoincrement," + 
            "auth_name text not null," +
            "myQuote text not null," +
            "category text not null);";

2.

public long populateQuotes(){

    ContentValues initialValues = new ContentValues();

    long[] rowIds = new long[authorName.length];

    // Add wilson quotes category: Anthropology
    for(int i = 0; i < 3; i++){
        initialValues.put(KEY_AUTHNAME,authorName[3]);
        initialValues.put(KEY_QUOTE,quoteRAW[i]);
        initialValues.put(KEY_CATEGORY,category[0]);
        rowIds[i] = qmDB.insertOrThrow(QUOTES_TABLE,null,initialValues);
    }
    // Add wilson quotes category: RAW
    for(int i = 3; i < 5; i++){
        initialValues.put(KEY_AUTHNAME,category[1]);
        rowIds[i] = qmDB.insertOrThrow(QUOTES_TABLE,initialValues);

    }
    // Add wilson quotes category: Philosophy
    for(int i = 5; i < 11; i++){
        initialValues.put(KEY_AUTHNAME,category[2]);
        rowIds[i] = qmDB.insertOrThrow(QUOTES_TABLE,initialValues);

    }
    // Add wilson quotes category: General Semantics
    for(int i = 11; i < 12; i++){
        initialValues.put(KEY_AUTHNAME,category[3]);
        rowIds[i] = qmDB.insertOrThrow(QUOTES_TABLE,initialValues);

    }
    // Add wilson quotes category: Humor
    for(int i = 11; i < 12; i++){
        initialValues.put(KEY_AUTHNAME,category[4]);
        rowIds[i] = qmDB.insertOrThrow(QUOTES_TABLE,initialValues);

    }

    return rowIds[0];
}

3.

public Cursor getQuotes(){

    /*
    return qmDB.query(QUOTES_TABLE,new String[]{
            KEY_QUOTE
            },KEY_AUTHNAME + "=" + "'Robert Anton Wilson'",null);*/



    //String who = authorName[position];
    return qmDB.rawQuery("SELECT _id as _id from Quotes WHERE auth_name = ?",new String[]{"'Robert Anton Wilson'"});

}

4.

// Create DB connection and open.
    dbm = new MyDBManager(this);
    dbm.open();

    // Call for the quotes to be queried,store results in cursor.
    myCursor = dbm.getQuotes();
    myCursor.moveToFirst();

    // Column quote does not exist?
    SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this,R.layout.quoterow,myCursor,new String[]{"myQuote"},new int[]{R.id.quote});
    this.setListAdapter(mAdapter);

    myCursor.close();

为了进一步说明,我已经包含了错误日志：
