Body
In a nutshell, I programmed myself into a corner by creating a CLR aggregate that performs row id concatenation, so I say: <pre><code>select SumKeys(id), name from SomeTable where name='multiple rows named this' </code></pre> and I get something like: <pre><code>SumKeys name -------- --------- 1,4,495 multiple rows named this </code></pre> But it dies when SumKeys gets > 8000 chars and I don't think I can do anything about it. As a quick fix (it's only failing 1% of the time for my application) I thought I might compress the string down and I thought some of you bright people out there might know a slick way to do this. Something like base64 made for 0-9 and a comma?

Guidance

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.
