android.database.sqlite.SQLiteException:table TABLE_NAME没有名为X的列(代码1):,编译时:INSERT INTO

我收到了上述错误,我真的无法找到我做错了什么。 我正在关注视频: https://www.youtube.com/watch?v=p8TaTgr4uKM 我看了android.database.sqlite.SQLiteException: table X has no column named Y: , while compiling: INSERT INTO 但我找不到错误。 我担心onCreate of RunsHistoryDataBase没有被调用因为我把它放在了Log.d和insertData中并且onCreate的Log.d没有显示出来并且insertData的Log.d确实显示出来了。 AnyWay我无法将数据插入数据库,我真的不明白为什么.. 有什么帮助吗?

这些是SQLiteDB的代码: 公共类RunsHistoryDataBase扩展了SQLiteOpenHelper {

public static final String dataBaseName = "RunsHistory.db";
public static final String tableName = "RunsHistoryTable";
public static final String colDate = "Date";
public static final String colPartnersName = "PartnersName";
public static final String colDuration = "Duration";
public static final String colDistance = "Distance";

public RunsHistoryDataBase(Context context) {
    // create the data base and the table.
    super(context, dataBaseName, null, 1);
}

@Override
public void onCreate(SQLiteDatabase db) {
    String createDataBase = "CREATE TABLE "+ tableName
            + "("
            + colDate +" TEXT PRIMARY KEY, "
            + colPartnersName + " TEXT, "
            + colDuration + " INTEGER, "
            + colDistance + " INTEGER);";
    db.execSQL(createDataBase);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IS EXISTS " + tableName);
    onCreate(db);
}

public boolean insertNewHistoryRun(Date date, String partnersName, int duration, int distance){

    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues contentValues = new ContentValues();
    contentValues.put(colDistance, distance);
    contentValues.put(colDuration, duration);
    contentValues.put(colDate, getFixedDateForPrint(date.toString()));
    contentValues.put(colPartnersName, partnersName);

    long result = db.insert(tableName, null, contentValues);

    if(result == -1){
        Log.d("result == -1","");
        return false;
    }
    return true;
}

public Cursor getAllData(){
    SQLiteDatabase db = this.getWritableDatabase();
    Cursor res = db.rawQuery("select * from "+tableName, null);
    return res;
}

}

这里的Ande是将数据插入db:
