来自SQL查询的自定义XML转换

Question

我遇到了一个问题，我必须对SQL Server查询产生的某些XML输出进行一些自定义编码。

<?xml version="1.0" encoding="UTF-8"?>
<Services xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="AriesImportSchema.xsd">
   <ServiceLineItem _clientURNExt="ABCD0401712EFG" _siteName="Jerrys Dental Care" _staffLogin="asdasgasdsf" _contractName="17-18 Part A" serviceDate="2018-02-23" program="Ryan Black" primaryService="Oral Dental Care" secondaryService="Routine Treatment" subservice="Surgery Treatment" unitsOfService="1" rateForUnitOfService="18722.12" measurementUnit="Visit" totalCost="18722.12" />
</Services>

用于生成要作为记录输出到ServiceLineItem标记的数据的查询非常简单：

select [_clientURNExt]
        , [_siteName]
        , [_staffLogin]
        , [_contractName]               
        , [serviceDate]
        , [program]
        , [primaryService]
        , [secondaryService]
        , [subservice]
        , 1 AS [unitsOfService]
        , [rateForUnitOfService] 
        , [measurementUnit]
        , [totalCost]
from ServiceLineItem 

Answer 1

类似这样的东西：

select [_clientURNExt] as [@_clientURNExt]      
from ServiceLineItem 
FOR XML PATH ('ServiceLineItem'),ROOT('Services');
