【中文标题】Android - 用于查找已删除标志的 SQLite 查询 - 未找到异常 DELETED 列【英文标题】：Android - SQLite query to look for the deleted flag - Exception DELETED column not found 【发布时间】：2014-07-19 06:28:44 【问题描述】：我正在尝试从 android 的联系人存储数据库中过滤掉联系人和数据。为此，我使用了 DELETED 过滤器。
来自here，它说可以使用Data.DELETED 访问它，但要么我做错了我无法弄清楚它在哪里，要么文档似乎有问题。
我对每个查询都使用了一个游标，但我不知道是哪一个导致了异常。 这是我的光标：
final Cursor cursorPhoneNumber = contentResolver.query(Phone.CONTENT_URI, projectionPhoneNumber, Data.MIMETYPE + " =? AND " + Phone.DELETED + " != 1", new String[]Phone.CONTENT_ITEM_TYPE, phoneQueryOrder);
final Cursor cursorStructuredName = contentResolver.query(Data.CONTENT_URI, projectionStructuredName, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]StructuredName.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionEmail, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]Email.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionStructuredPostal, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]StructuredPostal.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionOrganization, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]Organization.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionInstantMessaging, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]Im.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionNickname, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]Nickname.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionNote, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]Note.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionPhoto, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1",
new String[]android.provider.ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE,
null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionWebsites, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]Website.CONTENT_ITEM_TYPE, null);
final Cursor cursor = contentResolver.query(Data.CONTENT_URI, projectionEvents, Data.MIMETYPE + " =? AND " + Data.DELETED + " != 1", new String[]Event.CONTENT_ITEM_TYPE, null);
我的预测，不认为它们在这里是相关的，但如果它们真的是：
// Phone numbers
private static final String[] projectionPhoneNumber = new String[]

;

private static final String[] projectionNickname = new String[]

Nickname.NAME // 2
;
// Note
private static final String[] projectionNote = new String[]
Note.CONTACT_ID, // 0
Note.RAW_CONTACT_ID, // 1
Note.NOTE // 2
;
// Photo
private final String[] projectionPhoto = new String[]
android.provider.ContactsContract.CommonDataKinds.Photo.CONTACT_ID,
android.provider.ContactsContract.CommonDataKinds.Photo.RAW_CONTACT_ID
;
// Websites
private final String[] projectionWebsites = new String[]
Website.CONTACT_ID,
Website.RAW_CONTACT_ID,
Website.URL,
Website.TYPE
;
// Events
private final String[] projectionEvents = new String[]
Event.CONTACT_ID,
Event.RAW_CONTACT_ID,
Event.START_DATE,
Event.TYPE
;

编辑 导致异常的光标似乎是列表中的第一个光标。
【问题讨论】：
你的表定义显示了什么？请你把那个贴出来好吗？异常很明显，它没有找到该列。 这是Android的联系人存储数据库，Android存储联系人的地方。 DELETED 字段是一个整数。我回答你的问题了吗？ @AndroidAddict 我在联系人数据库中找不到名为deleted 的列：developer.android.com/reference/android/provider/…
【参考方案1】：
我认为您对正在访问的内容感到困惑。根据跟踪，您正在访问定义为here 的联系人表。你认为你正在访问raw contacts。
在定义中很明显，联系人表中没有delete 列，您的错误支持这一点。
