Sort when concatenating
When doing a concatenate the default is, understandably, that the concatenate is in order of ID. It would be very useful to be able to define in which order the concatenation is done. For example one might one to concatenate a series of events, but sort them on the evnt date, which may not be in the same order as the ID

Here we are tied to underlying database (namely MS SQL Server R2) features. So far they do not support ordering for custom aggregate functions such as Concatenate. Once they do this will open us the way to implement a lot of statistical calculations as well.

Have they announced any plans to do so?

The functionality is split between two products: the function is coded using .NET and they have documented an attribute to specify whether aggregate function is invariant to order of the data or not, but documentation states it is "reserved for future use". Yet, the attribute by itself does nothing - it is merely a flag for SQL to know whether the data it feeds to a function needs an ordering or not - but SQL documentation says nothing about the attribute.

Upcoming SQL 2012 release notes mention some improvements they've made for aggregate functions but its not clear whether they are applicable for custom aggregates. Yet the product is in early stage and documentation is obviously is not complete.

When you use "Concatenate" in a Summary, you may need to obtain the result sorted alphabetically...

It will be great if you can add this "sort" option.

Thanks

Merged with:
915 - Concatenate Summary, with the ability to sort.

@Kirill Is there any update on this as I now find myself in need of this functionality.
