what is the type of b?

It says

Column<DateTime>

and not

Column<DateTime?>

, so I guess it does not accept nullable values.

I'm using Exposed API

var b = date("b_column")

org.jetbrains.exposed.sql.Table public final fun date( name: String ): Column<DateTime>

@hyukchan var b = date("b_column").nullable()

O don't know the exposed API but I had the same guess as @Pavlo Liapota that the type is not

Column<DateTime?>

you need to make your column nullable. I am sure this is somehow possible.

oh ok !

Thanks a lot for your help all, especially @gcx11 who gave me the solution 🙂

Where did you find that "nullable()" trick ? It's not on the official documentation, is it ?

@hyukchan https://github.com/JetBrains/Exposed/blob/master/README.md And I thought it could done be this way
