Question

早上好，

我在AS / 400（绿色屏幕）内运行SQL查询，并且在提取别名列名时遇到问题。

这是我的剧本：

  /* Join forecast info with item warehouse info */
  SELECT item, itmdsc, 
         today,
         October, QSMOIB,
         (QSMOIB - October) AS Sales_less_October      

    FROM
         /* Summarizing forecast data in a SQL query */
         (SELECT  item, itmdsc, whse,
                 today, range,
                 (wk01 + wk02 + wk03 + wk04) AS October 
            FROM FCSTCUR) AS f      
    JOIN     
         /* Select "Qty sold this period" */
         (SELECT ITNOIB, WHIDIB, QSMOIB
            FROM ITEMBLL0) AS iw

      ON f.item = iw.ITNOIB AND
         f.whse = iw.WHIDIB 
   WHERE Sales_less_October <> 0
ORDER BY Sales_less_October ASC

当我运行它时，我收到错误：

Column or global variable SALES_LESS_OCTOBER not found.

但是，如果我将脚本更改为以下内容，它将按预期工作：

    /* Join forecast info with item warehouse info */
  SELECT item, itmdsc, 
         today,
         October, QSMOIB,
         (QSMOIB - October) /* AS Sales_less_October */   

    FROM
         /* Summarizing forecast data in a SQL query */
         (SELECT  item, itmdsc, whse,
                 today, range,
                 (wk01 + wk02 + wk03 + wk04) AS October 
            FROM FCSTCUR) AS f      
    JOIN     
         /* Select "Qty sold this period" */
         (SELECT ITNOIB, WHIDIB, QSMOIB
            FROM ITEMBLL0) AS iw

      ON f.item = iw.ITNOIB AND
         f.whse = iw.WHIDIB 
   WHERE (QSMOIB - October) <> 0
ORDER BY (QSMOIB - October) ASC

我简单地更换了＆＃34; Sales_less_October＆＃34; （QSMOIB - 十月）。

我真的希望能够使用别名，因为它比显示更清晰＆＃34;数字表达＆＃34;：

非常感谢，抱歉，我无法上传数据......它在我们的服务器上。

如果您想在val similarities = ratingPairs.map(row => { val ratings1 = sc.parallelize(row.getAs[Seq[Double]]("ratings1")) val ratings2 = sc.parallelize(row.getAs[Seq[Double]]("ratings2")) val corr:Double = Statistics.corr(ratings1, ratings2) Similarity(row.getAs[Long]("ID"), corr) })和<TextView android:id="@+id/textViewGuessGame" android:layout_width="wrap_content" android:layout_height="36dp" android:text="Guess Game" android:textSize="24sp" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toRightOf="parent" tools:layout_editor_absoluteY="6dp" /> <TextView android:id="@+id/textViewGameRules" android:layout_width="wrap_content" android:layout_height="61dp" android:text="Game rules: guess the wrong number and you loose a point. Guess the right number and get one point " app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toRightOf="parent" app:layout_constraintHorizontal_bias="0.13" tools:layout_editor_absoluteY="54dp" /> <TextView android:id="@+id/textViewResult" android:layout_width="wrap_content" android:layout_height="wrap_content" app:layout_constraintLeft_toLeftOf="parent" app:layout_constraintRight_toRightOf="parent" android:text="Points : 0 " tools:layout_editor_absoluteY="233dp" app:layout_constraintHorizontal_bias="0.455" /> <Button android:id="@+id/buttonL" android:layout_width="0dp" android:layout_height="wrap_content" android:text="0" tools:layout_editor_absoluteX="37dp" tools:layout_editor_absoluteY="146dp" /> <Button android:id="@+id/buttonR" android:layout_width="0dp" android:layout_height="wrap_content" android:text="0" tools:layout_editor_absoluteX="208dp" app:layout_constraintBaseline_toBaselineOf="@+id/buttonL" />子句中使用别名，则可以在WHERE中嵌套查询的其余部分时执行此操作：

ORDER BY
