Can I use DDA on a SQL query?

I suspect what you're looking to do isn't supported by DDA. DDA is designed for table-based cursoring access, optionally with a filter clause. If you want to do joins and data shaping you should look at the ADO.NET side of things which has all of those capabilities.
I shall focus my attention on ADO.NET then. Thank you for the fast reply!
I have an old Access application which I need to convert to .NET, and I'm currently evaluating VistaDB for this project.
The old app used the JET database engine. It has a lot of code written for cursor-based data access, so VistaDB's DDA appeals to me as a way to simplify conversion.
However, the data is frequently from a SQL query, which joins two or more tables. I've been able to make DDA work with a single table, but not with the result of a SQL query. I can't find a documented example of doing the latter, so maybe it's impossible, but I haven't seen anything that explicitly says it's impossible.
So, possible or not?
