Hello people, I have a question about SqlDelight (2.0 alpha).

I have Movie and TvShow tables, I wanna query them together, so I'm planning to create a View and map it to a sealed class in my data layer.

Before procede, I wanna make sure there isn't any native support to sealed classes in SqlDelight, in order to avoid to reinvent the wheel.
🙏

no nothing will generated sealed classes for you

Thanks for confirming 🍻

Curios why do want to use a sealed class?

[Davide Giuseppe Farella]

Movie and TvShow have many common fields, but some unique ones, so I can have a list of items with title, genres, poster (parent) and have a detailed screen with unique fields, like seasons for TvShow or releaseDate for Movie

Got it, okay creating some automapping sounds like an erroneous idea because it extremely depends on your internal data structure and its meaning. The generated classes don't contain data/values only but logic/meaning now, which is absolutely fine in OOP but hard to create with a generator without any information resulting in strange edge cases.
I do use sealed classes too in some projects but you have to do the mapping by yourself.

Yes I agree, but since all the magic that SqlDelight does, better to make sure 😄
