SQL where 内连接子句

Question

我正在使用 pgadminIII (postgreSQL)

我有以下表格：书，出版社, 订单行， ShopOrder.

与以下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

.

我想将它与 (WHERE Publisher.Name = "Smith Smitheson")

一起使用

我不知道放在哪里，或者如果我做对了，请帮忙吗？

Answer 1

...
INNER JOIN Publisher ON Book.PublisherID = Publisher.PublisherID AND Publisher.Name = 'Smith Smitheson' )
...

或

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
WHERE Publisher.Name = 'Smith Smitheson'
GROUP BY ShopOrder.OrderDate, Name, Book.BookID
