...snip code...
The one concern I have is that many db applications require runtime schema discovery as well as data returns -- so I think the compile time approach is limited to a particular class of applications that can be fully specified at compile time. DTL has dynamic views and integrates well with STL collections, so at some level they are setting the standard on this currently. Another interesting area of exploration for this would be integration with boost.multi_index.
Would there be any interest in including this in boost?
Yes, we really need a standard well thought out approach to accessing databases in C++.

I am currently going down this exact path and wanted to share what I ran into: 1- Boost does not have a 2dim "Table<>" - i.e. a Recordset 2- Boost.multi_index only works with concrete structures I would love it if I could use that to make a dynamic Table\ recordset 3- I have had to build my own Table<> by internally using boost.multiindex 4- Dtl is nice, however the thing that kicked me away from it is that it requires RTTI. This is a fact not clear in the documentation. It would be more than possible to do something along the lines of DRL and use boost.variant instead of having to resort to RTTI I believe boost is missing a "recordset" analolgy and I would hope that whatever is created is not "struct only" like boost.multi_index. (don't get me wrong I LOVE the multi_index - it just doesn't work dynamically) As a user I would like to see something along the lines of DTL \ Mysql++ http://dev.mysql.com/doc/plusplus/en/index.html It also sounds like you are thinking along the same lines (and we are working on similar things). I am more than happy to compare notes with you, either on this list or one -on-one if it is not-boost relevant, Thanks Brian Braatz
