SQL Cast函數語法錯誤

任何人都可以引導我在正確的方向嗎？我試過儘可能地編輯我的語法，並搜索了2個小時如何完成這項工作。但我無法讓我的CAST功能正常工作。我究竟做錯了什麼？SQL Cast函數語法錯誤

SELECT  dbo_orders.ordernumber, 
     dbo_orders.orderdate, 
     Sum([dbo_Order Details].priceperunit) AS sumofpriceperunit, 
     dbo_orders.producttotal, 
     Sum([dbo_Order Details].costperunit) AS sumofcostperunit, 
     dbo_orders.shippingtotal, 
     dbo_tracking.cost, 
     [dbo_Order Details].dropship, 
     dbo_orders.cartid 
CAST  ([dbo_Tracking].cost) AS number 
FROM  dbo_tracking 
INNER JOIN ([dbo_Order Details] 
INNER JOIN dbo_orders 
ON   [dbo_Order Details].ordernumber = dbo_orders.ordernumber) 
ON   dbo_tracking.numerickey = [dbo_Order Details].ordernumber 
GROUP BY dbo_orders.ordernumber, 
     dbo_orders.orderdate, 
     dbo_orders.producttotal, 
     dbo_orders.shippingtotal, 
     dbo_tracking.cost, 
     [dbo_Order Details].dropship, 
     dbo_orders.cartid 
HAVING  ((( 
             dbo_orders.orderdate)>=(#6/1/2016#) 
        AND  ( 
             dbo_orders.orderdate)<=(#6/30/2016#)));

通常情況下，在MS Access使用的類型轉換功能之一：

Cdec([dbo_Tracking].cost) AS number

如果你不想要一個小數，檢查documentation爲你想要的類型。

順便說一下，鑄造的正確語法包括一個類型。例如：

cast([dbo_Tracking].cost as decimal(20, 4))

感謝您的幫助。由於某些原因，它仍然給我語法錯誤（缺少運算符）。 – DRK

刪除有並且在一組之前查找一個where子句並且統計你的括號 – maSTAShuFu

MSACCESS鑄造功能

Cint -- cast to integer 
Clng -- long 
Cdbl -- double 
Csng - single 
Cstr - string 
Cbool - boolean 

SELECT clng(fieldName) FROM tableName

加入 ''，鑄領域中，除去具有條款和加入where子句。您可能需要相應地格式化日期。
