Yes, exactly my thought. For example, there should be some way to have a C++ program "download" constraint logic from the dbms and verify it against local data. This might mean a code generation step, or it might mean an embedded interpreter, although given how much C++ depends on ahead-of-time compilation there might be no point to the interpreter. For more dynamic languages, the interpreter might even be the language's native interpreter.
