    <p>I'm using SELECT ... FOR XML to generate XML and it creates exactly what I want to see - <em>in SSMS</em>. But...</p> <p>The problem I have is, the exported XML file has the entire XML body on a single line. It's valid XML, but how can I format the output? (one element per line, terminated with \r\n and preferably indented) The file should be human readable in notepad.</p> <p>Also, is there a better way to tack on the XML header?</p> <p>Of course I could write a CLR stored proc to do the export, seems like overkill though.

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.
