这是我在表字段中的 XML

<CtcConfiguration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <Ctc>3</Ctc>
    <SalaryComponent>
        <SalaryComponentConfiguration>
            <Name>Basic</Name>
            <DisplayOrder>0</DisplayOrder>
            <Value>5634655</Value>
        </SalaryComponentConfiguration>
        <SalaryComponentConfiguration>
            <Name>HR</Name>
            <DisplayOrder>0</DisplayOrder>
            <Value>1234</Value>
        </SalaryComponentConfiguration>
        <SalaryComponentConfiguration>
            <Name>medical</Name>
            <DisplayOrder>0</DisplayOrder>
            <Value>0</Value>
        </SalaryComponentConfiguration>
    </SalaryComponent>
</CtcConfiguration>

我希望node(DisplayOrder)根据node(Name). 例如，如果我将名称命名为医疗，它应该根据需要更新displayorder值。

这是我到目前为止所尝试的：

UPDATE payroll.pays set 
    CtcConfiguration.modify('replace value of (/CtcConfiguration/SalaryComponent/SalaryComponentConfiguration/DisplayOrder/text())[1] with ("99999")') 
where 
    CtcConfiguration.value('((/CtcConfiguration/SalaryComponent/SalaryComponentConfiguration/Name)[]/text())[1]','varchar(50)') = 'HR'

试试这样：

提示：此示例操作 ，<Value>但它也以相同的方式工作<DisplayOrder>。

DECLARE @mockupTable TABLE(ID INT IDENTITY, YourXML XML);
INSERT INTO @mockupTable VALUES
(N'<CtcConfiguration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <Ctc>3</Ctc>
    <SalaryComponent>
        <SalaryComponentConfiguration>
            <Name>Basic</Name>
            <DisplayOrder>0</DisplayOrder>
            <Value>5634655</Value>
        </SalaryComponentConfiguration>
        <SalaryComponentConfiguration>
            <Name>HR</Name>
            <DisplayOrder>0</DisplayOrder>
            <Value>1234</Value>
        </SalaryComponentConfiguration>
        <SalaryComponentConfiguration>
            <Name>medical</Name>
            <DisplayOrder>0</DisplayOrder>
            <Value>0</Value>
        </SalaryComponentConfiguration>
    </SalaryComponent>
</CtcConfiguration>');


DECLARE @AttributeName VARCHAR(100)=N'medical';
DECLARE @NewValue INT=12345;

UPDATE @mockupTable
SET YourXML.modify(N'replace value of (/CtcConfiguration
                                       /SalaryComponent
                                       /SalaryComponentConfiguration[(Name/text())[1]=sql:variable("@AttributeName")]
                                       /Value/text())[1] 
                     with sql:variable("@NewValue")');


SELECT * FROM @mockupTable;

简短说明

您的 XML 是一个相当简单的属性值模型（具有可见等级）。您使用XQuery 谓词过滤正确的属性并将其设置为特殊<Value>的。所以你必须寻找有特殊内容的<SalaryComponentConfiguration>地方。<Name>
