我的数据库需要存储的XML请求时,用户发送以及XML有2个通信元件,WP和SA,但他们没有固定的(我的意思是位置):MSSQL查询XML差异为了
<bms:OrgInfo>
<bms:Communications>
<bms:CommQualifier>WP</bms:CommQualifier>
<bms:CommPhone>5555551212</bms:CommPhone>
</bms:Communications>
<bms:Communications>
<bms:CommQualifier>SA</bms:CommQualifier>
<bms:Address>
<bms:Address1>1234 Test Avenue</bms:Address1>
<bms:Address2>1234 Test Avenue</bms:Address2>
<bms:City>Alamogordo</bms:City>
<bms:StateProvince>NM</bms:StateProvince>
<bms:PostalCode>88310</bms:PostalCode>
<bms:CountryCode>US</bms:CountryCode>
</bms:Address>
</bms:Communications>
</bms:OrgInfo>
有时候SA元素将是第一个。
如何查询它不用担心poistion
这里是我当前的查询,我使用的索引进行查询:
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[XmlStore]') AND type in (N'U'))
DROP TABLE [dbo].[XmlStore]
GO
CREATE TABLE [dbo].[XmlStore](
[XmlRequest] [xml] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
INSERT INTO [XmlStore]([XmlRequest]) VALUES('<?xml version="1.0" encoding="UTF-8"?>
<bms:OrgInfo xmlns:bms="http://example.org">
<bms:Communications>
<bms:CommQualifier>WP</bms:CommQualifier>
</bms:Communications>
<bms:Communications>
<bms:CommQualifier>SA</bms:CommQualifier>
</bms:Communications>
<bms:Communications>
<bms:CommQualifier>EM</bms:CommQualifier>
</bms:Communications>
</bms:OrgInfo>')
;WITH xmlnamespaces ('http://example.org' AS bms)
Select
t.XmlRequest.value('(/bms:OrgInfo/bms:Communications/bms:CommQualifier)[1]', 'nvarchar(100)') as WP_Value,
t.XmlRequest.value('(/bms:OrgInfo/bms:Communications/bms:CommQualifier)[2]', 'nvarchar(100)') as SA_Value,
t.XmlRequest.value('(/bms:OrgInfo/bms:Communications/bms:CommQualifier)[3]', 'nvarchar(100)') as EM_Value
FROM [XmlStore] AS t
DROP TABLE [dbo].[XmlStore]
这将是一个灾难,如果用户重新排序通讯元素!
我们可以看到你的脚本吗? – maSTAShuFu
