I have a table with xml column named xmlvalue.let xml value in those column are like shown below

<z>
<a>
<b>1</b>
<c>2</c>
</a>
<a>
<b>4</b>
<c>5</c>
.
.
.
so many tags similar to above
.
.
</a>
</z>
I want to add a new node called <new>here value should betaken from another column</new> inside the <z><a> for every row in that column with <new> tag having a value which is taken from another column "abc" for that row.(column abc is not a xml column) which is in same table.How can i do it using xml query or sql query?

Thank you

Can you post a sample input XML and the corresponding desired output XML (both as well-formed XML, so someone can copy it and use it in code). That is much easier to understand than word descriptions. Make the sample data representative enough, so it covers the variations that you would have in your real data.

do you mean this?


declare @test table
(
id int,
varval varchar(100),
x xml
)

insert @test
select 1,'abc',
'<z>
<a>
<b>1</b>
<c>2</c>
</a>
<a>
<b>4</b>
<c>5</c>
</a>
</z>' union all

select 2,'pqr',
'<z>
<a>
<b>21</b>
<c>22</c>
</a>
<a>
<b>14</b>
<c>52</c>
</a>
</z>'

UPDATE @test
SET x.modify('insert <new>{sql:column("varval")}</new>
              into /z[1]')
              
              SELECT * from @test
  

output
--------------------------------------------------------------------------------------
id	varval	x
--------------------------------------------------------------------------------------
1	abc	<z><a><b>1</b><c>2</c></a><a><b>4</b><c>5</c></a><new>abc</new></z>
2	pqr	<z><a><b>21</b><c>22</c></a><a><b>14</b><c>52</c></a><new>pqr</new></z>
