Sql Server: Update XML Node value with new value in table

Introduction:  In this article I am going to share how to modify or we can say replace XML node/ attribute value with new value in sql server table based on condition. 


Implementation: Let’s create a table variable and insert some dummy xml data in table

DECLARE @Employee TABLE(empXML XML)

INSERT INTO @Employee VALUES('<ROOT><Employee Id="101" Name="Hrithik" City="Noida" Age="32" /></ROOT>')
INSERT INTO @Employee VALUES('<ROOT><Employee Id="102" Name="Ranbeer" City="Delhi" Age="25" /></ROOT>')
INSERT INTO @Employee VALUES('<ROOT><Employee Id="103" Name="Akshay" City="Mumbai" Age="56" /></ROOT>')
INSERT INTO @Employee VALUES('<ROOT><Employee Id="104" Name="Sidharth" City="Kolkata" Age="33" /></ROOT>')
INSERT INTO @Employee VALUES('<ROOT><Employee Id="105" Name="Randeep" City="Chennai" Age="29" /></ROOT>')
INSERT INTO @Employee VALUES('<ROOT><Employee Id="106" Name="Varun" City="Bengaluru" Age="30" /></ROOT>')

Check table data
SELECT * FROM @Employee

Update XML node value with new value in table in sql server

Suppose we want to update value of city node to "Pune" where Employee Id is 105
Then the query will be as following:

UPDATE @Employee SET
empXML.modify('replace value of (ROOT/Employee/@City)[1] with "Pune"')
WHERE empXML.value('(ROOT/Employee/@Id)[1]', 'INT') = 105

Check updated table data now
SELECT * FROM @Employee
