來自XML列的多個值

我想弄清楚如何從表中的XML字段的多個節點（實際上是將XML存儲爲文本）獲取多個值。來自XML列的多個值

我見過幾種涉及將XML聲明爲變量並將其用作表格的方法，但我沒有看到這對我有用。 How to Extract data from xml column in sql 2008

我目前使用.value的獲得一些字段，但我不明白如何使它工作，因爲可以有多個LX01_AssignedNumber，我需要從每一個得到所有的ProcedureModifier的。

SELECT CAST(xmldata as xml).value('declare namespace ns1="http://schemas.microsoft.com/BizTalk/EDI/EDIFACT/2006/EnrichedMessageXML";declare namespace ns0="http://schemas.microsoft.com/BizTalk/EDI/X12/2006"; 
(/ns1:X12EnrichedMessage/TransactionSet/ns0:X12_00501_837_P/ns0:TS837_2000A_Loop/ns0:TS837_2000B_Loop/ns0:TS837_2300_Loop/ns0:TS837_2400_Loop/ns0:SV1_ProfessionalService/ns0:C003_CompositeMedicalProcedureIdentifier/C00303_ProcedureModifier) [1]', 'varchar(20)') AS RendAttendNPI 
FROM EDI_DATA

我如何從每個記錄所有的行號和所有程序修改器？

查找到SQL Server CROSS APPLY，你可以用它來切碎單XML數據分成多個行，例如：

;WITH XMLNAMESPACES ('http://schemas.microsoft.com/BizTalk/EDI/X12/2006' as ns0 
        ,'http://schemas.microsoft.com/BizTalk/EDI/EDIFACT/2006/EnrichedMessageXML' as ns1) 

SELECT 
    TS837_2400_Loop.value('(.//LX01_AssignedNumber)[1]', 'int') 'line_number' 
    ,C00303_ProcedureModifier.value('.', 'varchar(100)') 'procedure_modifier' 
FROM EDI_DATA 
    CROSS APPLY (select CONVERT(XML, xmldata)) as P(X) 
    CROSS APPLY X.nodes('.//ns0:TS837_2400_Loop') AS Q(TS837_2400_Loop) 
    CROSS APPLY TS837_2400_Loop.nodes('.//C00303_ProcedureModifier') AS R(C00303_ProcedureModifier)

sqlfiddle demo

出來放：

| line_number | procedure_modifier | 
|-------------|--------------------| 
|   1 |     AG | 
|   2 |     58 |

啊 - 那看上去更像是我想要比其他XML解析我已經找到。謝謝。我會盡量在接下來的幾天內完成這項工作。過去兩天我被困在了陪審團的職責中，現在一切都落後了。 –

嘿har07 - 有沒有辦法讓程序代碼（C0030 ** x ** _ ProcedureModifier）動態？可以有五個。或者是硬編碼它們的唯一方法，如果它們不存在，它們將是NULL？ –

謝謝 - 現在運行良好。我希望我可以使程序代碼具有動態性，但由於每個代碼具有不同的名稱，所以這可能是不可能的。 –
