SQL Server 2008：關鍵字'AS'附近的語法不正確

Question

我遇到了一個我繼承的程序的問題。我需要調整查詢，但是查詢不起作用。

這是我得到的查詢（不審判我，這不是我的查詢:)）

SELECT  
    SUM(DATEDIFF(day, verz1.BeginDatumAW, verz1.EindDatumAW) + 1) AS AantalDagen,  
    verz1.CodeBedrijf, verz1.CodeAfdeling, verz1.CodeSectie, 
    (SELECT TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
    FROM PEBSectie 
    WHERE (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = '00')) AS BSNS, 
    (SELECT TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
    FROM PEBSectie AS PEBSectie_1 
    WHERE (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = verz1.CodeAfdeling) AND (CodeGroep = '00')) AS AFD, 
    (SELECT TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
    FROM PEBSectie AS PEBSectie_1 
    WHERE (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = verz1.CodeAfdeling) AND (CodeGroep = verz1.CodeGroep) AND (CodeSectie = '00')) AS GRP, 
    (SELECT TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
    FROM PEBSectie AS PEBSectie_1 
    WHERE (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = verz1.CodeAfdeling) AND (CodeGroep = verz1.CodeGroep) AND (CodeSectie = verz1.CodeSectie)) AS SEC 
FROM   
    Verzorging AS verz1 
LEFT OUTER JOIN 
    AangepastWerk AS aw1 ON verz1.VerzorgingId = aw1.VerzorgingId 
WHERE  
    (verz1.EindDatumAW <= @EndDate) AND 
    (verz1.BeginDatumAW >= @StartDate) AND 
    (aw1.Verwijderd = 0) AND    <------------ First statement added 
    (aw1.NietErkend = 0 OR aw1.NietErkend IS NULL) AND 
    (DATEDIFF(day, verz1.BeginDatumAW, verz1.EindDatumAW) > 0)) 
GROUP BY 
    verz1.CodeBusiness, verz1.CodeBedrijf, verz1.CodeAfdeling, verz1.CodeGroep, 
    verz1.CodeSectie, verz1.TypeAWOfWO, verz1.TypeOngeval 
HAVING  
    (verz1.TypeAWOfWO = 'A') AND (verz1.TypeOngeval = 'AO') OR 
    (verz1.TypeAWOfWO = 'Arbeidsongeval') OR 
    (verz1.TypeAWOfWO = 'arbeidsongeval') 
UNION ALL 
SELECT  SUM(DATEDIFF(day, @StartDate, verz1.EindDatumAW) + 1) AS AantalDagen, verz1.CodeBedrijf, verz1.CodeAfdeling, verz1.CodeSectie, 
         (SELECT  TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
         FROM   PEBSectie AS PEBSectie_3 
         WHERE  (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = '00')) AS BSNS, 
         (SELECT  TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
         FROM   PEBSectie AS PEBSectie_1 
         WHERE  (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = verz1.CodeAfdeling) AND (CodeGroep = '00')) AS AFD, 
         (SELECT  TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
         FROM   PEBSectie AS PEBSectie_1 
         WHERE  (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = verz1.CodeAfdeling) AND (CodeGroep = verz1.CodeGroep) AND 
               (CodeSectie = '00')) AS GRP, 
         (SELECT  TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
         FROM   PEBSectie AS PEBSectie_1 
         WHERE  (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = verz1.CodeAfdeling) AND (CodeGroep = verz1.CodeGroep) AND 
               (CodeSectie = verz1.CodeSectie)) AS SEC 
FROM   Verzorging AS verz1 LEFT OUTER JOIN 
        AangepastWerk AS aw1 ON verz1.VerzorgingId = aw1.VerzorgingId 
WHERE  (verz1.EindDatumAW <= @EndDate) 
AND (verz1.EindDatumAW >= @StartDate) 
AND (verz1.BeginDatumAW < @StartDate) 
AND (aw1.Verwijderd = 0)     <------------ Second statement added 
AND (aw1.NietErkend = 0 OR aw1.NietErkend IS NULL) 
AND (DATEDIFF(day, verz1.BeginDatumAW, verz1.EindDatumAW) > 0) 
GROUP BY verz1.CodeBusiness, verz1.CodeBedrijf, verz1.CodeAfdeling, verz1.CodeGroep, verz1.CodeSectie, verz1.TypeAWOfWO, verz1.TypeOngeval 
HAVING  (verz1.TypeAWOfWO = 'A') AND (verz1.TypeOngeval = 'AO') OR 
        (verz1.TypeAWOfWO = 'Arbeidsongeval') OR 
        (verz1.TypeAWOfWO = 'arbeidsongeval') 

變化：在兩種情況報表添加以下行：

AND (aw1.Verwijderd = 0) 

我添加這個後，我不斷收到以下子查詢的問題（對於每個子查詢，我得到相同的錯誤）。

(SELECT  TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
         FROM   PEBSectie AS PEBSectie_3 
         WHERE  (CodeBusiness = verz1.CodeBusiness) AND (CodeAfdeling = '00')) AS BSNS, 

我得到的錯誤是：

消息156，級別15，狀態1，行 'AS' 關鍵字近28
不正確的語法。

我似乎無法弄清楚我做了什麼/出了什麼問題。我希望一雙清新的眼睛可能會看到我錯過的東西。

注意：後UNION ALL

感謝您對我所有的耐心的錯誤只發生

與親切的問候

編輯：如果可能的話：大要避免修改查詢。

Answer 1

大家好，

感謝您所有的時間投入到我的問題。一雙新鮮的眼睛（即使是一對非IT眼睛）突然發現了這個問題。在第一個查詢中有一個支架太多（其中語句）

(DATEDIFF(day, verz1.BeginDatumAW, verz1.EindDatumAW) > 0)) 

最後一個支架不應該在那裏。我被錯誤消息所矇蔽，並在第二個查詢中查找問題。舊的查詢如何仍然能夠產生有效的結果（即使語法無效）仍然讓我感到困惑。查詢本身將被重寫以避免更多問題。

日Thnx再次所有的時間

隨着親切的問候

Answer 2

你不能別名選擇表查詢..

(SELECT TOP (1) RTRIM(OmschrijvingSectie) AS Expr1 
FROM PEBSectie AS PEBSectie_1 
WHERE (CodeBusiness = verz1.CodeBusiness) AND 
     (CodeAfdeling =verz1.CodeAfdeling) AND 
     (CodeGroep = verz1.CodeGroep) AND          
     (CodeSectie = verz1.CodeSectie)) **AS SEC** 

是錯在這裏對所有表走樣。
