CQL request composition

Question

Is it possible to compose requests in CQL ?

I would like to write something like:

SELECT TYPES FROM ASSEMBLIES "myassemblie" WHERE IsUsing SELECT METHODS FROM ASSEMBLIES "myotherassemblie" WHERE IsStatic

Thanks, Vans

The NDepend team is proud to finally provides an elegant answer to this question :) Thanks to the new NDepend v4 Code Query LINQ (CQLinq) feature, what you are asking for can be written for example like:

let staticMethods = Application.Assemblies.WithName("nunit.core")
                    .ChildMethods().Where(m => m.IsStatic)

from t in Application.Assemblies.WithName("nunit.util")
          .ChildTypes().UsingAny(staticMethods )

let staticMethodsUsed = staticMethods.UsedBy(t)
select new { t, staticMethodsUsed  }

There are many other ways to write such query, but this way is certainly the most concise and optimized one (the top-right panel tells it is executed in 4ms):
