使用 T-SQL 解析 XML 数据
Parsing XML Data using T-SQL
我正在尝试使用 SQL Server 2019 解析 XML 数据。
我有以下数据集：
<?xml version='1.0' encoding='UTF-8'?>
<wd:Report_Data xmlns:wd="urn:com.test.report/Reported_Time_Blocks_for_a_Worker_s__-_Test_Worked_Hours_-_Copy">

<wd:Legal_Name_-_First_Name>TestFirstName</wd:Legal_Name_-_First_Name>
<wd:Legal_Name_-_Last_Name>TestLastName</wd:Legal_Name_-_Last_Name>
</wd:Worker_group>
<wd:Employee_Type wd:Descriptor="Property">
<wd:ID wd:type="WID">xxxxxxxxxxxxxxxxxxxxxxxxxxx</wd:ID>
<wd:ID wd:type="Employee_Type_ID">Regular</wd:ID>
</wd:Employee_Type>
<wd:Pay_Rate_Type wd:Descriptor="Salary">

</wd:Home_Cost_Center>
<wd:Home_Subarea wd:Descriptor="HS001 Test Home">

<wd:ID wd:type="Organization_Reference_ID">HS001</wd:ID>
<wd:ID wd:type="Custom_Organization_Reference_ID">HS001</wd:ID>
</wd:Home_Subarea>
<wd:Home_Job_Profile wd:Descriptor="Test Job Title">

<wd:ID wd:type="Job_Profile_ID">100000001</wd:ID>
</wd:Home_Job_Profile>
<wd:Reported_Date>2022-04-11-07:00</wd:Reported_Date>
<wd:Reported_Quantity>8</wd:Reported_Quantity>
<wd:Time_Entry_Code wd:Descriptor="Worked Time (Hours Only)">

<wd:ID wd:type="WID">xxxxxxxxxxxxxxxxxxxxxxxxxx</wd:ID>
<wd:ID wd:type="Time_Calculation_Tag_ID">Regular</wd:ID>
</wd:Calculation_Tags>
</wd:Report_Entry>
我知道如何获取一些数据，但我不知道如何使用多个行组。
我有这个查询可以提取 Employee_ID、Legal_Name_-First_Name 和 Legal_Name-_Last_Name ，但我不知道如何用它来拉 Employee_Type、Pay_Rate_Type 等：
DECLARE @XML XML
SET @XML = ( SELECT XMLData FROM #XML )
DECLARE @XML XML
SET @XML = ( SELECT XMLData FROM #XML )
;WITH XMLNAMESPACES( 'urn:com.test.report/Reported_Time_Blocks_for_a_Worker_s__-_Test_Worked_Hours_-_Copy' AS wd )
SELECT EmployeeId = Data.Col.value( 'wd:Employee_ID[1]', 'VARCHAR(12)' ),
FirstName = Data.Col.value( 'wd:Legal_Name_-_First_Name[1]', 'VARCHAR(100)' ),
LastName = Data.Col.value( 'wd:Legal_Name_-_Last_Name[1]', 'VARCHAR(100)' )
--INTO #EmployeeInformation
FROM @XML.nodes( 'wd:Report_Data/wd:Report_Entry/wd:Worker_group' ) Data( Col )
我实际上是在尝试从上面的 XML 中提取以下数据：
Employee_ID
Legal_Name_-_First_Name
Legal_Name_-_Last_Name
Employee_Type_ID
Pay_Rate_Type_ID
Pay_Rate
Cost_Center_Reference_ID
Reported_Date
Reported_Quantity
Home_Job_Profile_Descriptor
111111
TestFirstName
TestLastName
Regular

请尝试以下解决方案。
您可能需要调整数据类型。
