在SQL Server 2005中使用XQuery来获取XML内部文本

Question

如何使用XQuery选择XML节点的内部文本？

Microsoft Books Online显示了如何在下面检索属性:

DECLARE @myDoc xml
DECLARE @ProdID int
SET @myDoc = '<Root>
<ProductDescription ProductID="1" ProductName="Road Bike">
<Features>
  <Warranty>1 year parts and labor</Warranty>
  <Maintenance>3 year parts and labor extended maintenance is available</Maintenance>
</Features>
</ProductDescription>
</Root>'

SET @ProdID =  @myDoc.value('(/Root/ProductDescription/@ProductID)[1]', 'int' )
SELECT @ProdID

如何获取Warranty节点的内部文本值？

Answer 1

像这样的东西:

DECLARE @Warranty VARCHAR(50)

SET @Warranty = @myDoc.value('(/Root/ProductDescription/Features/Warranty/text())[1]', 'varchar(50)' )

SELECT @Warranty
