SQL SERVER path for xml

In SQL Server, you can store XML data in an XML data type column. The path for an XML column in SQL Server is simply the name of the column.
For example, if you have a table called "my_table" with an XML column called "my_xml_column", the path for the XML column would be:
my_table.my_xml_column
You can use this path in SQL queries to retrieve or manipulate the XML data stored in the column. For example, to extract the value of a specific element from an XML column, you could use a query like this:
SELECT my_xml_column.value('(/root/element)[1]', 'nvarchar(max)') AS element_value FROM my_table;
In this query, "root" is the name of the root element in the XML, "element" is the name of the element you want to extract, and "[1]" specifies the first occurrence of that element in the XML.
