優化器鎖提示選項錯誤

Question

我是一個新手希望你們可以幫助我。我現在正在查詢一個查詢，似乎我被這個錯誤優化器鎖提示選項卡住了。我以前沒有遇到過這個錯誤。

我遵循本教程從一個網站約SQL Pivot。除了當我使用EXEC sp_executesql運行它時，一切都很完美。我盡我所能來解決這個問題，但沒有運氣。它是我第一次在SQL服務器中使用Pivot。

請檢查下面我的代碼：

我正在實現的是，我試圖將大約50行到列我的存儲過程。

DECLARE @CustFeedCols AS NVARCHAR(4000) 
DECLARE @CustFeedQuery AS NVARCHAR(4000) 

SELECT @CustFeedCols = COALESCE(@CustFeedCols + ',','') + QUOTENAME(custfeed) 
FROM (SELECT DISTINCT TOP 1000 replace(replace(replace(replace(custfeed ,' ',''),'.',''),'-',''),'–','') as custfeed FROM efp_touchCRM.dbo.efp_customertouch 
WHERE custfeed <> '' AND custfeed is NOT null AND custfeed <> 'Sold Sample' 
ORDER BY custfeed) AS custfeed 

SELECT @CustFeedCols 

SET @CustFeedQuery = N'SELECT ' + @CustFeedCols + ' FROM efp_touchCRM.dbo.efp_customertouch PIVOT(GROUPING(custfeed)) FOR custfeed IN (' + @CustFeedCols + ')) AS P' 

SELECT @CustFeedQuery 

EXEC sp_executesql @CustFeedQuery --This is where the error appears. 
            --Incorrect syntax near '('. 

感謝各位的回覆！查看第二行提供的錯誤的編輯代碼。謝謝。

感謝。

有例子看看：
https://technet.microsoft.com/en-us/library/ms177410(v=sql.105).aspx

-- Pivot table with one row and five columns 
SELECT 'AverageCost' AS Cost_Sorted_By_Production_Days, 
[0], [1], [2], [3], [4] 
FROM 
(SELECT DaysToManufacture, StandardCost 
    FROM Production.Product) AS SourceTable 
PIVOT 
(
AVG(StandardCost) 
FOR DaysToManufacture IN ([0], [1], [2], [3], [4]) 
) AS PivotTable; 

在您的代碼：

1. 沒有聚集功能
2. 煩惱與括號

：

PIVOT 
(
    custfeed <<< 
) <<< 
FOR custfeed IN (
...)) as P
