问下面的SQLite语句引发异常有什么问题:表TABLE_NAME没有名为COLUMN_NAME的列

EN

private static final String KEY_ID = "og_nid";
private static final String KEY_TITLE = "og_title";
private static final String KEY_UID = "og_uid";
private static final String KEY_UID_NAME = "uid_name";

    public void onCreate(SQLiteDatabase db) {
            String CREATE_SURVEYS_TABLE = "CREATE TABLE IF NOT EXISTS " + TABLE_SURVEYS + "("
                    + KEY_ID + " INTEGER PRIMARY KEY, " + KEY_TITLE + " TEXT, "
                    + KEY_UID + " TEXT, " + KEY_UID_NAME + "TEXT "+ ")";
            db.execSQL(CREATE_SURVEYS_TABLE);
        }
void addSurvey(Survey survey) {
        SQLiteDatabase db = this.getWritableDatabase();
        this.onCreate(db);
        ContentValues values = new ContentValues();
        values.put(KEY_ID, survey.get_id()); // Contact Name
        values.put(KEY_TITLE, survey.get_title());
        values.put(KEY_UID, survey.get_uid());
        values.put(KEY_UID_NAME, survey.get_name());
        // Contact Phone

        // Inserting Row
        db.insert(TABLE_SURVEYS, null, values);
        db.close(); // Closing database connection
    }
