你能編輯這個問題來提供一個[最小，完整，可驗證的例子]（http://stackoverflow.com/help/mcve）？所有這些代碼可能沒有必要解決您的問題。 – laylarenee

您的查詢有它運行/邏輯錯誤的訂單。

您將一個VARCHAR由FLOAT因放置不當括號，我懷疑你的意思是先完成所有的數學和最終結果轉換爲VARCHAR執行字符串連接操作（添加百分號）。

此外，你沒有代碼格式/縮進，這將使這個錯誤很多更容易看到。

試試這個修改後的版本：

SELECT CONVERT(VARCHAR(100), 
      (
       select SUM(TransactionAmount) as saleamount 
       from ProductSaleInformation 
       where StoreCode=1 and RegionCode=1 
        AND BillDate Between '2015-06-01' AND '2015-10-31' 
      ) - (
       select SUM(TransactionAmount) as saleamount 
       from ProductSaleInformation 
       where StoreCode=1 and RegionCode=1 
        AND BillDate Between '2015-01-01' AND '2015-05-31' 
      )/(
       select SUM(TransactionAmount) as saleamount 
       from ProductSaleInformation 
       where StoreCode=1 and RegionCode=1 
        AND BillDate Between '2015-01-01' AND '2015-05-31' 
      )) + '%' AS SALESGROWTH

要float轉換爲varchar，您可以用CONVERT或CAST功能。像這樣：

DECLARE @float FLOAT = 1.2 
SELECT CONVERT(VARCHAR(20), @float) 
SELECT CAST(@float AS VARCHAR(20))
