我有一个简短的2记录XML文本,但是当我运行.value时,我只得到第一条记录。如何获取仅包含值的表格列表?
declare @x as xml
set @x = '<?xml version="1.0" encoding="UTF-8"?>
<vehicle>
<vehicleid>54142</vehicleid>
<networkid>21301</networkid>
<description>Demo #54143</description>
</vehicle>
<vehicle>
<vehicleid>54143</vehicleid>
<networkid>213101</networkid>
<description>Demo #54143</description>
</vehicle> '
SELECT @x.query('/*')
SELECT @x.value('(/vehicle/vehicleid/text())[1]', 'varchar(50)') as vehicleid,
@x.value('(/vehicle/description/text())[1]', 'varchar(50)') as description
go
结果:
<vehicle><vehicleid>54142</vehicleid><networkid>21301</networkid><description>Demo #54143</description></vehicle> (WRAP to next line)
<vehicle><vehicleid>54143</vehicleid><networkid>213101</networkid><description>Demo #54143</description></vehicle>
(1 row(s) affected)
vehicleid description
54142 Demo #54143

试试这个(有关详细信息,请参阅this question):
SELECT T.C.value('(vehicleid/text())[1]', 'varchar(50)') as vehicleid,
T.C.value('(description/text())[1]', 'varchar(50)') as description
from @x.nodes('//vehicle') as T(C)
@x.value
返回单个值,因此您需要从节点集合中查询以获得多个结果。

使用:
SELECT t.c.value('(vehicleid)[1]', 'varchar(50)') [vehicleid]
, t.c.value('(description)[1]', 'varchar(50)') [description]
FROM @x.nodes('//vehicle') t(c)
