Not helping me 😕

[robstoll]

what is the type of b?

[Pavlo Liapota]

It says Column<DateTime> and not Column<DateTime?>, so I guess it does not accept nullable values.

[hyukchan]

I'm using Exposed API

[hyukchan]

var b = date("b_column")

[hyukchan]

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

[gcx11]

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

[robstoll]

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.

[hyukchan]

oh ok !

[hyukchan]

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

[hyukchan]

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
