我正在使用pgadminIII(postgreSQL)
我有以下表格:Book,Publisher,OrderLine,ShopOrder.
使用以下SQL:
SELECT
Book.BookID AS "Book ID"
,Book.Title AS "Book title"
,SUM(OrderLine.quantity) AS "Number Ordered"
,ShopOrder.OrderDate AS "Order Date"
FROM (((Book
INNER JOIN OrderLine
ON Book.BookID = OrderLine.BookID)
INNER JOIN Publisher
ON Book.PublisherID = Publisher.PublisherID )
INNER JOIN ShopOrder
ON OrderLine.ShopOrderID = ShopOrder.ShopOrderID)
GROUP BY ShopOrder.OrderDate, Name, Book.BookID
.
我想用这个(WHERE Publisher.Name = "Smith Smitheson")
我不知道该把它放在哪里,或者如果我做得对,请帮忙吗？
