v0.24.2 solution https://wirekang.github.io/kysely-playground/?p=f&i=-NSehWt8xk5lVTFiR4S9

Never seen SqlBool

It's a new union type added @ 0.24.x, Basically boolean | 0 | 1

Maybe kysely-codegen should use it in boolean fields?

kysely-codegen has more context

e.g. MySQL uses 1 | 0

so it should generate more precise types
