Introduction : In this article I am going to share how to parse and read data from XML data type column of sql server table.

In previous article i explained How to Update multiple xml node values with new values in table and Parse xml and get data as comma separated string format and Read or parse xml data and insert into sql table and Delete or select first or last n records from table and Find all primary and foreign key constraints on each or any table in database


Sql Server: Select or Read XML Column Data from table
Implementation : Let’s create an employee table using table variable for demonstration purpose and insert some dummy data along with xml data in xml type column of table. DECLARE @Employee TABLE ( EmployeeId INT , Age INT , empXML XML ) INSERT INTO @Employee ( EmployeeId , Age , empXML ) VALUES ( 101 , 22 , '<ROOT><Employee Country="India" State="Haryana" City="Hissar" /></ROOT>' ) INSERT INTO @Employee ( EmployeeId , Age , empXML ) VALUES ( 102 , 25 , '<ROOT><Employee Country="India" State="Punjab" City="Patiala" /></ROOT>' ) INSERT INTO @Employee ( EmployeeId , Age , empXML ) VALUES ( 103 , 32 , '<ROOT><Employee Country="India" State="Maharashtra" City="Mumbai" /></ROOT>' ) INSERT INTO @Employee ( EmployeeId , Age , empXML ) VALUES ( 104 , 21 , '<ROOT><Employee Country="India" State="Himachal" City="Shimla" /></ROOT>' ) Check table data SELECT * FROM @Employee

Now the query to read data from XML column and select as table will be as:

SELECT EmployeeId , Age , col . value ( '@Country' , 'VARCHAR(100)' ) AS Country , col . value ( '@State' , 'VARCHAR(100)' ) AS State , col . value ( '@City' , 'VARCHAR(100)' ) AS City FROM @Employee CROSS APPLY empXML . nodes ( 'ROOT/Employee' ) tab ( col );

Check updated table data now

SELECT * FROM @Employee

Result will be as shown in image above.
