<description><p>Dit is een faketekst. Alles wat hier staat is slechts om een indruk te geven van het grafische effect van tekst op deze plek. Wat u hier leest is een voorbeeldtekst. Deze wordt later vervangen door de uiteindelijke tekst, die nu nog niet bekend is. De faketekst is dus een tekst die eigenlijk nergens over gaat. Het grappige is, dat mensen deze toch vaak lezen. Zelfs als men weet dat het om een faketekst gaat, lezen ze toch door.</p>

SELECT T.C.value('.', 'varchar(100)') as productid
FROM @myOrder.nodes('(/genxml/items/genxml/productid)') as T(C)
按顺序给出两个产品的两行。 但是如何用f.i获得一些额外的列。 node / genxml / items / genxml / productname
中的productname答案 0 :(得分：0)
一种选择是停在genxml，而不是将1个级别导航到产品，然后选择您的详细信息。
更新：添加了一个级别的导航。您可以根据您的起点继续为每个级别扩展此范围。由于我们在T（C）中使用了/ genxml / items / genxml /，然后我们使用这个级别并在T1（C2）中再次下降。我去了这个范围（样本）以保持我的select部分小/可读。
SELECT
T.C.query('productid').value('.', 'varchar(100)') AS productid
,T.C.query('productname').value('.', 'varchar(100)') productname
,T.C.query('totalweight').value('.', 'float') totalweight
,T1.C2.query('txtbarcode').value('.', 'varchar(100)') txtbarcode
FROM @myOrder.nodes('(/genxml/items/genxml/.)') as T(C)
CROSS APPLY T.c.nodes('(productxml/genxml/models/genxml/textbox/.)') as T1(C2)
--few levels down navigatig all the way to textbox
该查询仅用于使用给定的样本导航产品详细信息。希望它有所帮助。
