How to loop and parse xml parameter in sql server stored procedure

Question

I want to write a stored procedure that accept an XML parameter, parsing it's elements and inserting them in a table. This is my XML:

I want to loop in that parameter(such as a foreach in C#), retrieving each person, then parsing it's data(ID,NAME,LASTNAME) inserting them in a table that has 3 fields.

How can do that?

Answer 1

Try this statement:

SELECT
   Pers.value('(ID)[1]', 'int') as 'ID',
   Pers.value('(Name)[1]', 'Varchar(50)') as 'Name',
   Pers.value('(LastName)[1]', 'varchar(50)') as 'LastName'
FROM
   @YourXml.nodes('/Employees/Person') as EMP(Pers)

This gives you a nice, row/column representation of that data.

And of course, you can extend that to be the second part in an INSERT statement:

INSERT INTO dbo.YourTargetTable(ID, Name, LastName)
  SELECT
     Pers.value('(ID)[1]', 'int') as 'ID',
      Pers.value('(Name)[1]', 'Varchar(50)') as 'Name',
     Pers.value('(LastName)[1]', 'varchar(50)') as 'LastName'
  FROM
     @YourXml.nodes('/Employees/Person') as EMP(Pers)

Done - no loops or cursors or any awful stuff like that needed! :-)
