對取包含字段時用到了FOR XML PATH這個功能，可以方便的把包含列組織成A,B,C的形式。然后使用CROSS APPLY得出最終的結(jié)果。腳本定義如下：
USE AdventureWorks;
GO
DROP INDEX IX_SalesOrderHeader_CustomerID ON Sales.SalesOrderHeader
GO
CREATE INDEX IX_SalesOrderHeader_CustomerID ON Sales.SalesOrderHeader(CustomerID)
INCLUDE(ShipDate,Freight)
GO
--sp_helpindex不能反應(yīng)出包含字段
EXEC sp_helpindex 'Sales.SalesOrderHeader'
GO
