窄下SQL結果集

我有這樣的SQL命令：窄下SQL結果集

SELECT RecordedBy as 'Recorded By', COUNT(*) Total 
FROM mytable 
WHERE 
StartedDate BETWEEN DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP), '00:01AM') 
AND DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP), '11:59PM') 
group by RecordedBy order by Total desc

我想做到的是通過嵌入這個SQL在另外一個更加細化此查詢的結果，而不改變原來的SQL 。

比如，我想通過RecordedBy子句來縮小原來的SQL：我雖然做的是這樣的：

select * from mytable in 
(
    SELECT RecordedBy as 'Recorded By', COUNT(*) Total FROM mytable 
    WHERE StartedDate BETWEEN 
    DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP),'00:01AM') 
    AND DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP),'11:59PM') 
    group by RecordedBy order by Total desc 
)

但是，當然，這將導致語法錯誤。誰能想到，我現在失去了一些東西？

外部選擇的要求/提煉是什麼？您不能在內部查詢中編寫按條款的訂單。 – TechDo 2013-03-12 10:16:25

優化原始的sql（SELECT RecordedBy as'Recorded By'，COUNT（*）Total F ....） – MaVRoSCy 2013-03-12 10:17:13

您也不能通過引用原始表名來引用子查詢。當你修復了其他的語法錯誤時，只要從（SUBQUERY HERE）中選擇*。 – 2013-03-12 10:18:32

你可以試試這個

select * from 
(
    SELECT RecordedBy as 'Recorded By', 
     COUNT(*) Total 
    FROM mytable 
    WHERE StartedDate 
     BETWEEN 
      DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP),'00:01AM') 
      AND 
      DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP), '11:59PM') 
) as TAB 
group by TAB.RecordedBy 
order by TAB.Total desc

我收到此錯誤消息1033級別15狀態1行3 ORDER BY子句在視圖，內聯函數，派生表，子查詢和公用表表達式中無效，除非還指定了TOP或FOR XML。 ' – MaVRoSCy 2013-03-12 10:25:18

正確的語法是：

select * from 
(
    SELECT RecordedBy as 'Recorded By', COUNT(*) Total FROM mytable 
    WHERE StartedDate BETWEEN 
    DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP),'00:01AM') 
    AND DATEADD(day, DATEDIFF(day, 0, CURRENT_TIMESTAMP),'11:59PM') 
    group by RecordedBy order by Total desc 
) mytable

試試吧。

我收到了同樣的錯誤，因爲@yogi上面的答案 – MaVRoSCy 2013-03-12 10:28:51

@MaVRoSCy是否在視圖中執行查詢或者只是在普通查詢窗口中執行查詢？ – 2013-03-12 10:38:07

爲了這個工作，我必須從內部的SQL到外部的'order by'子句。如果我把它放在鍵入它時，我得到這個錯誤ORDER BY子句在視圖，內聯函數，派生表，子查詢和公用表表達式中是無效的，除非還指定了TOP或FOR XML。 ' – MaVRoSCy 2013-03-12 10:39:27
