SQLite的語法錯誤與Android

任何人都可以點我在哪裏是語法錯誤嗎？SQLite的語法錯誤與Android

出於某種原因，我無法找到它。我不確定我的方法是否正確（我仍在測試）。

這裏是我的代碼：

final Cursor cursor; 

    final String[] PROJECTION_SEARCH_FOR_CONTACT = new String[] { 
     Contacts._ID, 
     Contacts.DISPLAY_NAME, 
     Contacts.PHOTO_ID, 
     "name_raw_contact_id", 
     Contacts.Data.DATA1 // Telephone number 
    }; 

    // Search by Display Name 
    if(where == 0) 
    { 
     cursor = contentResolver.query(Data.CONTENT_URI, 
             PROJECTION_SEARCH_FOR_CONTACT, 
             Contacts.DISPLAY_NAME + " LIKE '" + searchFor + "%' AND " + Data.MIMETYPE + " = " + Contacts.CONTENT_ITEM_TYPE, 
             null, 
             null); 
    } 

    // Search by Phone Number 
    else if(where == 1) 
    { 
     cursor = contentResolver.query(Data.CONTENT_URI, 
             PROJECTION_SEARCH_FOR_CONTACT, 
             Contacts.Data.DATA1+ " LIKE '" + searchFor + "%' AND " + Contacts.Data.MIMETYPE + " = " + Phone.CONTENT_ITEM_TYPE, 
             null, 
             null); 
    } 

    // Search by Email 
    else 
    { 
     cursor = contentResolver.query(Data.CONTENT_URI, 
             PROJECTION_SEARCH_FOR_CONTACT, 
             Contacts.Data.DATA1+ " LIKE '" + searchFor + "%' AND " + Contacts.Data.MIMETYPE + " = " + Email.CONTENT_ITEM_TYPE, 
             null, 
             null); 
    }

這裏是異常錯誤。

... mimetype = vnd.android.cursor.item/contact

你需要把字符串字面量''單引號。例如，

... Data.MIMETYPE + " = '" + Contacts.CONTENT_ITEM_TYPE + "'"

和類似的其他情況。

謝謝你，這就是你（我，在這種情況下）發生時，要編寫它快速的測試目的。所以解決方法是使用光標上的選擇字段。像這樣：'光標= contentResolver.query（Data.CONTENT_URI， \t \t \t \t \t \t \t \t \t \t \t PROJECTION_SEARCH_FOR_CONTACT， \t \t \t \t \t \t \t \t \t \t \t Contacts.DISPLAY_NAME + 「LIKE「」 + searchFor + 「％」 AND 」+ Data.MIMETYPE +「=？」， \t \t \t \t \t \t \t \t \t \t \t新的String [] {Contacts.CONTENT_ITEM_TYPE}， \t \t \t \t \t \t \t \t \t \t \t NULL）;' – dazito

是的，這也將工作。使用'？'佔位符文字是一個好習慣，即使在這種情況下，沒有直接的好處（也不傷害）。 – laalto
