データベースに新しいエントリを追加しようとすると、以下に示すようなエラーが発生します。私は今何時間もそれを探していますが、何が悪いのかを見つけることができません。どんな入力でも素晴らしいでしょう！

LogCatからのエラーは次のとおりです。

私のデータベースファイル。

そして、私のAddNewDayファイル。

  public class AddNewDay {

 //private variables
     int _id;
     String _date;
     int _hours;
     int _ubtillegg;
     int _brutto;        

     // Empty constructor
     public AddNewDay(){
     }
     // constructor
     public AddNewDay(int id, String date, int hours, int ubtillegg, int            brutto){
      this._id = id;
      this._date = date;
      this._hours = hours;
      this._ubtillegg = ubtillegg;
      this._brutto = brutto;
     }       
     // constructor
     public AddNewDay(String date, int hours, int brutto){
      this._date = date;
      this._hours = hours;
      this._brutto = brutto;
     }
     // getting ID
     public int getID(){
      return this._id;
     }

     // setting id
     public void setID(int id){
      this._id = id;
     }

     // getting date
     public  String getDate(){
      return this._date;
     }

     // setting date
     public void setDate(String date){
      this._date = date;
     }

     // getting hours
     public int getHours(){
      return this._hours;
     }

     // setting hours
     public void setHours(int hours){
      this._hours = hours;
     }

     // getting ubtillegg
     public int getUb(){
      return this._ubtillegg;
     }

     // setting ubtillegg
     public void setUb(int ub){
      this._ubtillegg = ub;
     }

     // getting brutto
     public int getBrutto(){
      return this._brutto;
     }

     // setting brutto
     public void setBrutto(int brutto){
      this._brutto = brutto;
     }

             public String toString() {
         return _date + " jobbet du " + _hours + " timer.";
             }  
            }

そして、これが私がデータベースに新しいエントリを追加する方法です。

        // # Makes a new object of newday.
        AddNewDay newday = new AddNewDay ();
        newday._date = "21.03.2013";
        newday._id = 1;
        newday._hours = 4;
        newday._ubtillegg = 1500;

        // # Open databse connection and writes new day.
        DatabaseHandler connect = new DatabaseHandler (this);
        connect.addDay(newday);

        // # Updates the dblist with entries.
        GlobalVariables.dblist = connect.getAllContacts();

だから基本的に私は解決策を見つけました。私はそれがどれほど愚かだったかについてまだ混乱しています。とクッキリデータベース作品i超敏感素材！私の問題は、最後の「INTEGER」値に空白を忘れていたことです。だから" INTEGER"私が書いた代わりに、それは私に代わりに「brutto」"INTEGER"と呼ばれる行を与えました。"bruttoINTEGER"したがって、空白がエラーでした。createTable 関数を次のように書き直しました。

 public void onCreate(SQLiteDatabase db) {
   String CREATE_DAY_TABLE = "CREATE TABLE " + TABLE_DAYS + "(" 
 + KEY_ID + " INTEGER PRIMARY KEY," + KEY_DATE + " TEXT," + KEY_HOURS + " INTEGER, " 
 + KEY_UB + " INTEGER," + KEY_BRUTTO + " INTEGER" + ");"; 
 db.execSQL(CREATE_DAY_TABLE);
 }

よくわかりませんが、「ub」フィールドと「brutto」フィールドの前のクエリで「,」を忘れたのかもしれません

文字列 CREATE_DAY_TABLE = "CREATE TABLE" + TABLE_DAYS + "(" + KEY_ID + " INTEGER PRIMARY KEY," + KEY_DATE + " TEXT," + KEY_HOURS + " INTEGER PRIMARY KEY, " + KEY_UB + " INTEGER PRIMARY KEY, " + KEY_BRUTTO + "整数主キー" + ")"; デシベル.execSQL(CREATE_DAY_TABLE);
