</ListOrderItemsResult>

我想选择每一个，并提出以下代码，但只能检索第一个项目和数量

SELECT  doc.value('(OrderItems/OrderItem/OrderItemId)[1]','nvarchar(255)') AS 'OrderItemId' ,doc.value('(OrderItems/OrderItem/QuantityOrdered)[1]', 'int') AS 'QuantityOrdered' 
FROM    @xml.nodes('/ListOrderItemsResult') AS ref ( doc )

任何人都可以提供一个解决方案，它将返回所有项目，即XML中的3个项目。我知道它与[1]实例有关，但无法确定如何返回所有项目。

Answer 1

SELECT  doc.value('./OrderItemId[1]/text()[1]','nvarchar(255)') AS 'OrderItemId',
        doc.value('./QuantityOrdered[1]/text()[1]', 'int') AS 'QuantityOrdered' 
FROM    @xml.nodes('/ListOrderItemsResult/OrderItems/*') AS ref ( doc )
