Hi guys ! I'm trying to use Kotlin Exposed DSL to update a column value to null. Though I'm having this error. Can anyone help me please ? 🙂

? can be null

and I'm trying to do : A.update { it[A.b] = null }

i think it is looking for Generics over "Cannot Infer type parameter" on the set functions.

Hi again, using Kotlin Exposed DSL, joining the same table with itself gives me ambigous column definition error with Oracle ...

I'm using exactly the example of this: https://github.com/JetBrains/Exposed/wiki/DSL#alias

oh, found my answer ! You need to use alias on columns too : sequelTable[StarWarsFilms.id].alias("exmpl")

Use the Force

the inline output shows only a little part

and there's nothing on the console

how to capture an optional group in a regex?

I need it for this:

This works. But the comment at the end of the SQL insert (

-- A comment

in this case) should be optional. If I add a

?

at the end of the brackets it matches, but it's not captured anymore.

(Yes, I know about

StringBuilder

.)

Another milestone for Kotlin: Today’s item on TheDailyWTF is on Kotlin. https://thedailywtf.com/articles/null-thought

hmm... thanks for the input... yes Alex that is correct.... app is pretty much gathering RSS feeds and serving them out via browser, ios, android.

I was kind of hoping to do it all in one language with one IDE... its really the only thing about the Kotlin language that has me excited about it, that its being positioned as a Java based silver bullet.

One project too...

even if you wanted to use Kotlin Native for iOS, you’d still need Swift for the UI layer

Instead of making a least common denominator app, you should embrace what makes the different platforms unique

With whatever you decide to do, keep in mind that Kotlin is only the programming language. You’ll still need to learn the underlying frameworks, as Android, iOS, Spring Boot, Ktor, React, etc. all have their own large ecosystems to deal with. They all can be used with Kotlin as the source language, but you’re still locked into the frameworks and ecosystems that exist for what you’re wanting to build, which does help limit the number of decisions you need to make, but means you will also have to learn about these other frameworks and not just pure Kotlin.

Your suggestion might make sense steve, I have definitely considered that approach... and your write casey, which is why I'm having a tough time... what do I want to learn... I know that whatever I pick, it will paint me into one corner or another. I've actually gotten pretty far with kotlin-exposed, spring-boot, kotlin and gradle on the server side, development is pretty fast, faster thean when I made a similar app with raw python and PHP that's for sure... that in itself is a little scary, all the dependancies on top of dependancies. Gradle.kts has been very difficult to get used to (my first build system too), but I am starting to comprehend it. Transient dependency overlaping versions has been an issue... one package uses 1.27 of kotlin-std the other uses 1.31 kinda thing, largely ignoring these warnings if I can't solve them fast...

Any recommendations for APM that plays especially nicely with kotlin? We're using ktor/exposed but didn't want to cross post across 3 channels.

Hi, is there some rest service testing framework for Kotlin similar to Spring WebFlux+WebTestClient

@vpriscan what library are you using

It has something to do with @HttpClientDsl
