将group by添加到Oracle Query并获取错误

Question

Error after add group by and aggregation functions

此查询在没有group by和aggregate函数的情况下运行良好。在我添加group by和aggregate函数之后，它给了我这个错误。我是查询的首发。任何进步都会有所帮助。该公司正在使用Netsuite作为ERP系统。 Netsuite正在使用Oracle数据库。我正在使用ODBC连接到他们的数据库。

Select to_number(to_char(Transactions.trandate, 'YYYY')) as Year, 
       to_number(to_char(Transactions.trandate, 'MM')) as Month,
       NVL(Parent.name, Entity.name) as Customer, 
       Case 
           When Upper(Substr(Replace(Items.name,'.',''),1,4)) IN ('MEAL', 'BASE', 'BOLT', 'BITE', 'FUEL')
           THEN Upper(Substr(Replace(Items.name,'.',''),1,4))
           ELSE Items.name
       END as Item,
       Accounts.type_name as Account, 
       -sum(Transaction_lines.amount) as Sales
From Transactions
Left Join Transaction_lines ON Transactions.transaction_id=Transaction_lines.Transaction_id
Left Join Items ON Transaction_lines.item_id=Items.item_id
Left Join Accounts ON Transaction_lines.account_id=Accounts.account_id
Left Join Entity ON Transactions.entity_id=Entity.entity_id
Left Join Entity as Parent on Entity.parent_id=Parent.entity_id
Where transactions.trandate >= '2013-1-1' 
  and Transactions.transaction_type IN ('Invoice', 'Item Fulfillment', 'Cash Sale') 
  and Accounts.type_name IN ('Income', 'Expense', 'Cost of Goods Sold')

Group By 
    to_number(to_char(Transactions.trandate, 'YYYY')),   
    to_number(to_char(Transactions.trandate, 'MM')),
    NVL(Parent.name, Entity.name), 
    Case 
      When Upper(Substr(Replace(Items.name,'.',''),1,4)) IN ('MEAL', 'BASE', 'BOLT', 'BITE', 'FUEL')
           THEN Upper(Substr(Replace(Items.name,'.',''),1,4))
           ELSE Items.name
    END,
    Accounts.type_name
Order By Year, Month, Customer, Item, Account

Answer 1

您说没有GROUP BY的查询有效。

然后利用你的别名。

SELECT Year, Month, Customer, Item, Account, -sum(Amount) as Sales
FROM ( 
        YOUR WORKING QUERY
     ) T
GROUP BY Year, Month, Customer, Item, Account
Order By Year, Month, Customer, Item, Account
