要使行成为列，您需要使用交叉表查询：

TRANSFORM Count(Animal_Types.Code)
SELECT Customers.Name, Customers.Stall_Number, Sum(Transaction_Details.Weight) AS TotalWeight
FROM (Customers INNER JOIN Transactions ON Customers.ID = Transactions.Customer) INNER JOIN ((Animal_Types INNER JOIN Carcass ON Animal_Types.ID = Carcass.Animal_Type) INNER JOIN Transaction_Details ON Carcass.ID = Transaction_Details.Carcass) ON Transactions.ID = Transaction_Details.Transaction
GROUP BY Customers.Name, Customers.Stall_Number, Animal_Types.Code
