안드로이드 sql 문 관련 질문입니다(rawQuery)

Question

dbHelper_child_update= DBHelper_child.getsInstance(this);
db_child_update = dbHelper_child_update.getWritableDatabase();
ContentValues contentValues;
cursor = db_child_update.rawQuery("SELECT "+ MemoContract_child.MemoEntry._ID + ","
        + MemoContract_child.MemoEntry.COLUMN_NAME_SUCCESS_COUNT + "," + MemoContract_child.MemoEntry.COLUMN_NAME_FAIL_COUNT
        +" FROM "+ MemoContract_child.MemoEntry.TABLE_NAME+" ORDER BY " +
        ""+ MemoContract_child.MemoEntry._ID,null);

여기서 <result colunme>expected got, 'fail'

에러가 납니다 무엇이 잘못 됬나여...?
