Andrei,
So if I'm understanding you correctly, if structs are used, and there's a
database
change, then the app has to be rebuilt.
Yes. Touched to update the structs and rebuilt.
If Variants, then only the app's config
file has to be updated (or the app can look in the database to get such
information) - have I got this right?
Yah. The exact behavior depends on the assumption the app makes about
the resultset. Consider:
auto result = db.sql(queryString);
enforce(result.front[0].type == typeid(double));
...
In this case you'd pretty much need to touch the code if the queryString
returns something else than a double in the first column.
