How to Convert XML Data to SQL Database Table

Introduction: In this article I am going to explain how to select or convert xml data to sql table format.


Implementation: Let’s create two examples to understand how easily we can convert xml data to table format.

Example 1: Suppose we have xml data in following format

DECLARE @xml XML= '<ROOT>
<EMPLOYEE Id="1" Name="Tarun" Age="25" Gender="Male"/>
<EMPLOYEE Id="2" Name="Ritu" Age="27" Gender="Female"/>
<EMPLOYEE Id="3" Name="Arun" Age="24" Gender="Male"/>
<EMPLOYEE Id="4" Name="Jatin" Age="22" Gender="Male"/>
<EMPLOYEE Id="5" Name="Rohan" Age="29" Gender="Male"/>
<EMPLOYEE Id="6" Name="Pooja" Age="20" Gender="Female"/>
</ROOT>'

And we want to select or convert it into table format.
Then the query will be as:

SELECT col.value('@Id','INT') AS EmployeeId, col.value('@Name','VARCHAR(100)') AS EmployeeName,
col.value('@Age','INT') AS Age, col.value('@Gender','VARCHAR(10)') AS Gender
FROM @xml.nodes('/ROOT/EMPLOYEE') tab(col)

Output:
EmployeeId
EmployeeName
Age
Gender
1
Tarun
25
Male
2
Ritu
27
Female
3
Arun
24
Male
4
Jatin
22
Male
5
Rohan
29
Male
6
Pooja
20
Female

Example 2: Suppose we have xml data in following format

DECLARE @xml XML='<ROOT>
<EmployeeId>2</EmployeeId>
<EmployeeId>6</EmployeeId>
<EmployeeId>8</EmployeeId>
</ROOT>'

And we want to select or convert it into table format.
Then the query will be as:

SELECT col.value('.','INT') AS EmployeeId FROM @xml.nodes('/ROOT/EmployeeId')tab(col)

Output:
EmployeeId
2
6
8
