Assume that your table is named <code>YourTable</code> and you have one <code>ID</code> column and <code>XMLCol</code> column. The update statement could look like this to change the XML where <code>ID</code> is 1.</p> <pre><code>update T set XMLCol.modify('replace value of (/image/FilePath[1]/text())[1] with sql:column("T2.FilePath")') from YourTable as T cross apply (select replace(XMLCol.value('(/image/FilePath)[1]', 'varchar(100)'), '+', '_') ) as T2(FilePath) where T.ID = 1 </code></pre> <p><strong>Edit</strong></p> <p>It is not possible to update more than one node at a time with <code>.modify()</code>. You have to do this in a loop. The script below uses <code>@T</code> as a test table. You should replace that with whatever your table is called. <code>@T</code> has an <code>ID</code> column and the script assumes that you only update one row at a time and that you know the ID for that row. There are some comments in the code that explains what I do. Don't hesitate to ask if there are something I should make clearer.</p> <pre><code>-- Test table declare @T table(ID int, XMLCol xml) -- Sample data insert into @T values (1, '&lt;mediadata&gt; &lt;image&gt; &lt;FileName&gt;BUF2011-450&lt;/FileName&gt; &lt;FilePath&gt;1/uploadedImages/Products/Indoor_Fun/Puzzles___Brain_Teasers/Puzzles/2000+_Pieces/BUF2011-450.jpg&lt;/FilePath&gt; &lt;Thumbnails&gt; &lt;Thumbnail&gt; &lt;FileName&gt;BUF2011-450&lt;/FileName&gt; &lt;FilePath&gt;2/uploadedImages/Products/Indoor_Fun/Puzzles___Brain_Teasers/Puzzles/2000+_Pieces/thumb_BUF2011-450_Large.jpg&lt;/FilePath&gt; &lt;/Thumbnail&gt; &lt;Thumbnail&gt; &lt;FileName&gt;BUF2011-450&lt;/FileName&gt; &lt;FilePath&gt;3/uploadedImages/Products/Indoor_Fun/Puzzles___Brain_Teasers/Puzzles/2000+_Pieces/thumb_BUF2011-450_Small.jpg&lt;/FilePath&gt; &lt;/Thumbnail&gt; &lt;/Thumbnails&gt; &lt;/image&gt; &lt;/mediadata&gt; ') -- ID for the row you need to update declare @ID int set @ID = 1 -- Loop variable, node to update declare @Pos int set @Pos = 1 -- The number of nodes to update declare @Count int -- Get the number of FilePath nodes select @Count = XMLCol.query('count(//FilePath)').value('.', 'int') from @T where ID = @ID while @Pos &lt;= @Count begin update T set XMLCol.modify('replace value of ((//FilePath)[sql:variable("@Pos")]/text())[1] with sql:column("T2.FilePath")') from @T as T cross apply (select replace(T.XMLCol. query('(//FilePath)[sql:variable("@Pos")]'). value('.', 'varchar(100)'), '+', '_') ) as T2(FilePath) where T.ID = @ID set @Pos += 1 end </code></pre>

    2. CO@Mikael Eriksson ..I am kind of confused because I have 1 million records and only few records have problems so how does this work without a where clause to update only those records. can you please write a syntax as if the table and column already exists in the database like update table_name set column_name = '_' etc etc to understand easily

    3. COMikael's code is basically doing: `UPDATE TABLE set filepath = REPLACE(filepath, '+', '_')` It works differently in XML though. The XML Methods don't permit much tsql, so he is basically joining to a query that exposes that value as a column (the cross apply), applying the TSQL function to perform the replace, then replacing the old value with the new value (xmlCol.modify()).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
