安卓：表沒有名爲「變量名」 MySQL數據庫錯誤

我越來越又像一個錯誤顯示belowe當我嘗試把我的數據庫中的新條目列。我現在搜索幾個小時，但我無法檢測到什麼是錯的。任何輸入都會很棒！安卓：表沒有名爲「變量名」 MySQL數據庫錯誤

這裏是logcat的的錯誤。

我數據庫文件。

public class DatabaseHandler extends SQLiteOpenHelper {

    db.insert(TABLE_DAYS, null, values); 
    db.close(); // Closing database connection 
} 

// Get single day 
AddNewDay getContact(int id) { 
    SQLiteDatabase db = this.getReadableDatabase(); 

    Cursor cursor = db.query(TABLE_DAYS, new String[] { KEY_ID, 
    KEY_DATE, KEY_HOURS, KEY_BRUTTO, KEY_UB }, KEY_ID + "=?",

    Cursor cursor = db.rawQuery(selectQuery, null); 

    // looping through all rows and adding to list 
    if (cursor.moveToFirst()) {

    cursor.close(); 

    // return count 
    return cursor.getCount(); 
} 


}

然後我AddNewDay文件。

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."; 
      } 
      }

這就是我如何添加在數據庫中的新條目。

 // # 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();

你錯過了你的CREATE_DAY_TABLE字符串一些逗號。沒有他們，你就沒有一個名爲「brutto」的專欄。乍一看，它看起來像你需要他們在小時和UB（至少）。 – 2013-02-27 22:47:34

另外，你可以通過shell連接到數據庫，並且可能會有所幫助（在那裏轉儲表結構，或導出它並使用像SQLite Manager這樣的工具）。 – 2013-02-27 22:51:15

哦，修正了那些。更新的問題。沒有改變任何東西，但我認爲它修復了一個可能的錯誤編號2. :) – chriskvik 2013-02-27 22:54:02

所以basicly我找到了解決辦法。我仍然對它有多愚蠢感到困惑。並明確數據庫工作我超敏感的材料！我的問題是我忘記了最後一個「INTEGER」值中的空格。所以，而不是" INTEGER"我寫了"INTEGER"，這給了我一排"bruttoINTEGER"，而不是「brutto」。所以白色空間是錯誤的。我重寫了createTable函數：

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); 
}

我不確定，但也許你忘了 「」 在之前 「UB」 和 「brutto」 領域

字符串CREATE_DAY_TABLE = 「CREATE TABLE」 + TABLE_DAYS + 「（」 查詢+ KEY_ID + 「INTEGER PRIMARY KEY，」 + KEY_DATE + 「TEXT」 + KEY_HOURS + 「INTEGER PRIMARY KEY，」 + KEY_UB + 「INTEGER PRIMARY KEY，」 + KEY_BRUTTO + 「INTEGER PRIMARY KEY」 + 「）」; db.execSQL（CREATE_DAY_TABLE）;

感謝您的建議。但不幸的是它沒有改變任何東西。它看起來像是將變量傳遞給列。或者創建列字段KEY_UB。 – chriskvik 2013-02-27 22:57:56

是的，抱歉是我的錯，不是我的錯，不是我的錯，我添加'，' – Flip120 2013-02-27 22:58:02

我同意上面的iNzzane。這個問題主要是由語法造成的。例如，以前我的代碼是正確的。這就是：

String CREATE_PRODUCTS_TABLE = "CREATE TABLE " + TABLE_PRODUCTS + "(" 
       + COLUMN_ID + " INTEGER PRIMARY KEY," + COLUMN_MESSAGEADDRESS 
       + " TEXT," + COLUMN_MESSAGEBODY + " TEXT " + ")"; 

the above code was running correct but i added another column and it started causing the mentioned error. below is the erroneous code: 

String CREATE_PRODUCTS_TABLE = "CREATE TABLE " + TABLE_PRODUCTS + "(" 
       + COLUMN_ID + " INTEGER PRIMARY KEY," + COLUMN_MESSAGEADDRESS 
       + " TEXT," + COLUMN_MESSAGEBODY + " TEXT" + COLUMN_MESSAGETIME + " LONG" + ")"; 

as you can see, when i added the new column i forgot to include a comma after type TEXT. this means that when this code is executed, there will be syntax error as the compiler will read the last part as: 

COLUMN_MESSAGEBODY TEXTCOLUMN_MESSAGETIME LONG 

as opposed to: 

COLUMN_MESSAGEBODY TEXT, COLUMN_MESSAGETIME LONG 

solution: ensure that your syntax is correct and you heed to spaces and commas.
