如何在分組時使用Select Case中的列別名

Question

我試圖弄清楚如何在分組時使用select分支中的列別名。我有我的查詢工作。唯一的問題是AccountsDescription是實際的列名，我需要結果集來使用別名Account。有人能指引我朝着正確的方向嗎？

Select 
    Case 
     When GROUPING (AccountDescription) = 1 then '*ALL*' 
     Else AccountDescription 
    End As AccountDescription, 
     Vendors.VendorState As State, 
     Sum(InvoiceLineItems.InvoiceLineItemAmount) as LineItemSum 
From 
    InvoiceLineItems Join GLAccounts On 
    InvoiceLineItems.AccountNo = GLAccounts.AccountNo 
    Join Invoices On 
    InvoiceLineItems.InvoiceID = Invoices.InvoiceID 
    Join Vendors On 
    Invoices.VendorID = Vendors.VendorID 
Group by GLAccounts.AccountDescription, Vendors.VendorState with Cube

如果你寫As AccountDescription，將其更改爲As Account。
