Example: Specify XSINIL with the ELEMENTS Directive

  • Artikkeli

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

The following query specifies the ELEMENTS directive to generate element-centric XML from the query result.

Example

USE AdventureWorks2022;
GO
SELECT ProductID, Name, Color
FROM Production.Product
FOR XML RAW, ELEMENTS;
GO

This is the partial result.

<row>
  <ProductID>1</ProductID>
  <Name>Adjustable Race</Name>
</row>
...
<row>
  <ProductID>317</ProductID>
  <Name>LL Crankarm</Name>
  <Color>Black</Color>
</row>

Because the Color column has null values for some products, the resulting XML won't generate the corresponding <Color> element. By adding the XSINIL directive with ELEMENTS, you can generate the <Color> element even for NULL color values in the result set.

USE AdventureWorks2022;
GO
SELECT ProductID, Name, Color
FROM Production.Product
FOR XML RAW, ELEMENTS XSINIL;

This is the partial result:

<row xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <ProductID>1</ProductID>
  <Name>Adjustable Race</Name>
  <Color xsi:nil="true" />
</row>
...
<row>
  <ProductID>317</ProductID>
  <Name>LL Crankarm</Name>
  <Color>Black</Color>
</row>
