    <p>I have a table like this (simplified):</p> <pre><code>ID | Name | Parent --------------------------------- 1 | IND | NULL 2 | INS | 5 3 | CON | NULL 4 | AUT | 1 5 | FIN | NULL 6 | PHA | 1 7 | CFIN | 5 8 | CMRKT | 7 </code></pre> <p>DDL:</p> <pre><code>CREATE TABLE [dbo].[tblIndustryCodes]( [IdIndustry] [int] IDENTITY(1,1) NOT NULL, [IndustryCode] [nvarchar](5) NULL, [IndustryName] [nvarchar](50) NULL, [ParentId] [int] NULL, CONSTRAINT [PK_tblIndustryCodes] PRIMARY KEY CLUSTERED ( [IdIndustry] ASC)) </code></pre> <p>INSERTS:</p> <pre><code>INSERT INTO [tblIndustryCodes] ([IndustryCode] ,[IndustryName] ,[ParentId]) VALUES ('IND','Industry',NULL), ('PHARM','Pharmacy',1), ('FIN','Finance',NULL), ('CFIN','Corporate Finance',3), ('CMRKT','Capital Markets',4) </code></pre> <p>And I'd like to generate a xml file from it which is structured according to the parent IDs</p> <p>like this (simplified)</p> <pre><code>&lt;IND&gt; &lt;AUT&gt; &lt;PHA&gt; &lt;CON&gt; &lt;FIN&gt; &lt;CFIN&gt; &lt;CMRKT&gt; </code></pre> <p>I believe its done maybe with some kinda recursion or something like that, but I don't know how. Any help is greatly appreciated!</p> <p>edit: Its a SQL Server Express 2008</p> <p>I don't really care if it's valid XML or not, because I only use it to populate a treeview control.</p> <p>edit2: I would probably use "FOR XML EXPLICIT" but I don't really understand the syntax when <strong>there is no fixed maximum depth of the tree.</strong> </p> <p>edit3: for easier understanding of the task, I added the DDL for the table</p>

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.

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