内联表值函数FUNCTION

创建一个内联表值函数：

 1 USE TSQLFundamentals2008;
 2 IF OBJECT_ID(‘dbo.fn_GetCustOrders‘) IS NOT NULL
 3   DROP FUNCTION dbo.fn_GetCustOrders;
 4 GO
 5 CREATE FUNCTION dbo.fn_GetCustOrders
 6   (@cid AS INT) RETURNS TABLE
 7 AS
 8 RETURN
 9   SELECT orderid, custid, empid, orderdate, requireddate,
10     shippeddate, shipperid, freight, shipname, shipaddress, shipcity,
11     shipregion, shippostalcode, shipcountry
12   FROM Sales.Orders
13   WHERE custid = @cid;
14 GO

对这个函数进行查询：

1 SELECT orderid, custid
2 FROM dbo.fn_GetCustOrders(1) AS CO;
