整数プライマリキーが自動インクリメントしない

Question

私はSQLiteとinteger主キーautoincrementフィールドに関する問題があります。 私はROWID列を呼び出すことによってIDを持つことができますが、私は '_id'が必要です。ここで

は私のテーブルを作成するために私のクエリです：

private static final String TABLE_FACEBOOK_IMPORTED_CONTACTS = "facebook_imported_contacts"; 
    private static final String COL_ID = "_id"; 
    private static final String COL_FACEBOOK_ID = "facebookId"; 
    private static final String COL_PHONE_CONTACT_ID = "phoneContactId"; 
    private static final String COL_FIRST_NAME = "firstName"; 
    private static final String COL_LAST_NAME= "lastName"; 
    private static final String COL_BIRTH_DATE = "birthDate"; 
    private static final String COL_GROUP = "contactGroup"; 
    private static final String COL_MAIL_ADDRESS = "mailAddress"; 
    private static final String COL_PHONE_NUMBER = "phoneNumber"; 



    public static final String CREATE_FACEBOOK_IMPORT_BDD = "" + 
      "CREATE TABLE "+TABLE_FACEBOOK_IMPORTED_CONTACTS+" ("+ 
      COL_ID + " integer primary key autoincrement," + 
      COL_FACEBOOK_ID +" INT," + 
      COL_PHONE_CONTACT_ID +" INT, " + 
      COL_FIRST_NAME +" TEXT NOT NULL," + 
      COL_LAST_NAME +" TEXT NOT NULL, " + 
      COL_BIRTH_DATE +" TEXT," + 
      COL_GROUP +" TEXT," + 
      COL_MAIL_ADDRESS +" TEXT," + 
      COL_PHONE_NUMBER +" TEXT);"; 

だから私は、エラーメッセージを持っていません。 COL_IDフィールド（_id）が自動インクリメントしないことを除いて、すべてが機能します。ここ は、コードの残りの部分である：

public class FacebookContactDAO { 
    private static final int DB_VERSION = 1; 
    private static final String DB_NAME = "automatic_sms.db"; 

    private static final String TABLE_FACEBOOK_IMPORTED_CONTACTS = "facebook_imported_contacts"; 
    private static final String COL_ID = "_id"; 
    private static final int NUM_COL_ID = 0; 

    private static final String COL_FACEBOOK_ID = "facebookId"; 
    private static final int NUM_COL_FACEBOOK_ID = 1; 

    private static final String COL_PHONE_CONTACT_ID = "phoneContactId"; 
    private static final int NUM_COL_PHONE_CONTACT_ID = 2; 

    public static final String COL_FIRST_NAME = "firstName"; 
    private static final int NUM_COL_FIRST_NAME = 3; 

    public static final String COL_LAST_NAME= "lastName"; 
    private static final int NUM_COL_LAST_NAME = 4; 

    private static final String COL_BIRTH_DATE = "birthDate"; 
    private static final int NUM_COL_BIRTH_DATE = 5; 

    private static final String COL_GROUP = "contactGroup"; 
    private static final int NUM_COL_GROUP = 6; 

    private static final String COL_MAIL_ADDRESS = "mailAddress"; 
    private static final int NUM_COL_MAIL_ADDRESS = 7; 

    private static final String COL_PHONE_NUMBER = "phoneNumber"; 
    private static final int NUM_COL_PHONE_NUMBER = 8; 

    private SQLiteDatabase database; 
    private SQLiteDB mySQLiteDB; 



    public FacebookContactDAO(Context context){ 
     //On créer la BDD et sa table 
     mySQLiteDB = new SQLiteDB(context, DB_NAME, null, DB_VERSION); 
    } 

    public void open(){ 
     database = mySQLiteDB.getWritableDatabase(); 
     //database.execSQL("DROP TABLE " + TABLE_FACEBOOK_IMPORTED_CONTACTS + ";"); 
     //database.execSQL(SQLiteDB.CREATE_FACEBOOK_IMPORT_BDD); 
    } 

    public void close(){ 
     database.close(); 
    } 

    public SQLiteDatabase getDB(){ 
     return database; 
    } 

    public long insert(FacebookContact contact){ 


     ContentValues contactValues = new ContentValues(); 

     contactValues.put(COL_FACEBOOK_ID, contact.getFacebookId()); 
     contactValues.put(COL_PHONE_CONTACT_ID, contact.getPhoneContactId()); 
     contactValues.put(COL_FIRST_NAME, contact.getFirstName()); 
     contactValues.put(COL_LAST_NAME, contact.getLastName()); 
     contactValues.put(COL_BIRTH_DATE, contact.getBirthDate()); 
     contactValues.put(COL_GROUP, contact.getGroup()); 
     contactValues.put(COL_MAIL_ADDRESS, contact.getMailAddress()); 
     contactValues.put(COL_PHONE_NUMBER, contact.getPhoneNumber()); 

     return database.insert(TABLE_FACEBOOK_IMPORTED_CONTACTS, null, contactValues); 
    } 

    public int update(int id, FacebookContact contact){ 
     ContentValues contactValues = new ContentValues(); 
     //contactValues.put(COL_ID, contact.getId()); // (shouldn't be able to change the id) 
     contactValues.put(COL_FACEBOOK_ID, contact.getFacebookId()); 
     contactValues.put(COL_PHONE_CONTACT_ID, contact.getPhoneContactId()); 
     contactValues.put(COL_FIRST_NAME, contact.getFirstName()); 
     contactValues.put(COL_LAST_NAME, contact.getLastName()); 
     contactValues.put(COL_BIRTH_DATE, contact.getBirthDate()); 
     contactValues.put(COL_GROUP, contact.getGroup()); 
     contactValues.put(COL_MAIL_ADDRESS, contact.getMailAddress()); 
     contactValues.put(COL_PHONE_NUMBER, contact.getPhoneNumber()); 

     return database.update(TABLE_FACEBOOK_IMPORTED_CONTACTS, contactValues, COL_ID + " = " +id, null); 
    } 

    public int remove(long facebookId){ 
     //Suppression d'un livre de la BDD grâce à l'ID 
     return database.delete(TABLE_FACEBOOK_IMPORTED_CONTACTS, COL_FACEBOOK_ID + " = " +facebookId, null); 
    } 
    public int removeEverything(){ 
     //Suppression d'un livre de la BDD grâce à l'ID 
     return database.delete(TABLE_FACEBOOK_IMPORTED_CONTACTS, "1 = 1", null); 
    } 

    public FacebookContact getByFacebookId(long facebookId) { 

     Cursor queryResult = database.query( TABLE_FACEBOOK_IMPORTED_CONTACTS, 
            new String[] {COL_ID,COL_FACEBOOK_ID, COL_PHONE_CONTACT_ID, COL_FIRST_NAME,COL_LAST_NAME,COL_BIRTH_DATE,COL_GROUP,COL_MAIL_ADDRESS,COL_PHONE_NUMBER}, 
            COL_FACEBOOK_ID + " = " + facebookId + "", 
            null, null, null, null); 
     FacebookContact contact = cursorToFacebookContact(queryResult); 
     queryResult.close(); 

     return contact; 
    } 

    public Cursor getAll() { 

     Cursor queryResult = database.query( TABLE_FACEBOOK_IMPORTED_CONTACTS, 
            new String[] {COL_ID,COL_FACEBOOK_ID, COL_PHONE_CONTACT_ID, COL_FIRST_NAME,COL_LAST_NAME,COL_BIRTH_DATE,COL_GROUP,COL_MAIL_ADDRESS,COL_PHONE_NUMBER}, 
            "1", 
            null, null, null, COL_LAST_NAME+","+COL_FIRST_NAME); 

     //FacebookContact contact = cursorToFacebookontact(queryResult); 
     //queryResult.close(); 
     return queryResult; 
    } 


    private FacebookContact cursorToFacebookContact(Cursor c){ 
     if (c.getCount() == 0) 
      return null; 

     c.moveToFirst(); 

     FacebookContact contact = new FacebookContact(); 

     contact.setId(c.getInt(NUM_COL_ID)); 
     contact.setFacebookId(c.getInt(NUM_COL_FACEBOOK_ID)); 
     contact.setPhoneContactId(c.getInt(NUM_COL_PHONE_CONTACT_ID)); 
     contact.setFirstName(c.getString(NUM_COL_FIRST_NAME)); 
     contact.setLastName(c.getString(NUM_COL_LAST_NAME)); 
     contact.setBirthDate(c.getString(NUM_COL_BIRTH_DATE)); 
     contact.setGroup(c.getString(NUM_COL_GROUP)); 
     contact.setMailAddress(c.getString(NUM_COL_MAIL_ADDRESS)); 
     contact.setPhoneNumber(c.getString(NUM_COL_PHONE_NUMBER)); 

     c.close(); 

     return contact; 
    } 

} 

たぶん問題は、プライベートFacebookContact cursorToFacebookContactから来ています。

情報が必要な場合は教えてください。

おかげで、事前に

Answer 1

は、私はあなたのautoincrementキーワードのようにアンダースコアが必要であることを考える：auto_increment

Answer 2

削除自動インクリメント

モデルクラス変数との両方の取得および設定方法を持っていることを確認し

- モーダルクラス---

public int getId(){ 
     return this._id; 
    } 


public void setId(int id){ 
     this._id= id; 
    } 

これらの2つの方法があなたの表は、次のSQLコードのように作成されている場合

参照モデルクラスにcompulsaryです：

private static final String CREATE_CATEGORY_TABLE= 
      "CREATE TABLE "+CATEGORY_TABLE+"(" 
        +CAT_ID+" INTEGER PRIMARY KEY , " 
        +CATEGORY+" TEXT, " 
        + DESCRIPTION+" TEXT, " 
        +CAT_TYPE+" TEXT)"; 

私はあなたの中にフィールドを追加する必要はありませんCAT_ID= _id declared;

を持っていますDatabaseManagerメソッドを追加します。

しかし、データベースマネージャ のように値のリストを返すときにidを設定する必要があります。

public ArrayList<Category> getCategory(){ 
     ArrayList<Category> listofCat= new ArrayList<Category>(); 
     String selquery="SELECT * FROM "+CATEGORY_TABLE; 
     SQLiteDatabase db= this.getReadableDatabase(); 
     Cursor cursor= db.rawQuery(selquery,null); 

     if(cursor.moveToFirst()){ 
      do{ 
       Category category= new Category(); 
       category.setId(cursor.getInt(cursor.getColumnIndex(CAT_ID))); 
       category.setCatName(cursor.getString(cursor.getColumnIndex(CATEGORY))); 
       category.setCatDesc(cursor.getString(cursor.getColumnIndex(DESCRIPTION))); 
       category.setCatType(cursor.getString(cursor.getColumnIndex(CAT_TYPE))); 

       listofCat.add(category); 
      }while (cursor.moveToNext()); 

     } 
     cursor.close(); 
     return listofCat; 

このメソッドは、自分のコンテキストでカテゴリのリストを返します。

このようにコードを並べ替えると機能します。
