Using XQUERY/Modify to replace a piece of my XML with value from varchar field
I have a table:
MyTable
config as XML
title as varchar(255)
In MyTable.config I have XML in the following structure:
<configuration pagetitle="myConfig">
<column>
<row>
<component id="1" type="MyPiece" title="My Title" text="junk" />
</row>
</column>
</configuration>
I need a script to inject the value of MyTable.text into the text attribute of the component node in my config XML.
I know this is wrong, but I want to do something similar:
UPDATE MyTable SET config.configuration.colum
I believe I want to use XQUERY and the modify function.

From my understanding these kinds of operations only can affect one node at a time, so you may need to build function if replacement need is more complex then you can call the user defined function passing XML so that each time it is only operating on one but you can be overall executing on an entire dataset.
