使用SQL CASE語句來替換GROUP BY

Question

我正在使用SQL Server，我遇到以下問題，我正在跳一個人可以幫助我。

我收到此錯誤

Column 'TransactionsLine.Text' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. 

我不想包含在GROUP文本BY子句是，使查詢運行，但問題是沒有在該領域的其他文字，我不希望它分組我只想用文本替換名稱與文本匹配的案件

當我添加文本到我得到這個結果的組。

問題正是錯誤所說的。您正在選擇TransactionsLine.text，這不在group by子句中。

你可能要放案在group by條款：

select StockItemCode as CODE, 
    (
     case 
      when StockItems.Description like 'item%' 
       then TransactionsLine.text 
      else StockItems.Description 
      end 
     ) as name, 
    SUM(ItemQuantity) as Sales 
from Transactions 
inner join TransactionsLine on Transactions.id = TransactionsLine.TransactionID 
inner join StockItems on TransactionsLine.StockItemID = StockItems.id 
where location = @location 
    and Department = 43 
    and Transactions.date between @FROM 
     and @TO 
    and TransactionTypeID in (3, 32) 
group by StockItemCode, 
    case 
     when StockItems.Description like 'item%' 
      then TransactionsLine.text 
     else StockItems.Description 
     end
