I've just accidentally found this impressive project, I've never even heard about before - https://github.com/komapper/komapper. Definitely worth checking when someone is looking for a Kotlin ORM.

Hi, I'm the author of the project. Thank you for bringing this up. I hope you will try Komapper. I'm looking forward to your feedback.

Hi, @Toshihiro Nakamura
As the reference docs are unfortunately not in English (yet?), could you please tell me if there is a way to call native SQL queries in komapper?

[Toshihiro Nakamura]

Komapper supports SQL templates. Using this feature, you can write the following:

val sql = "select * from address where street = /*street*/'test'"
val query = QueryDsl.fromTemplate(sql).bind(
    object {
        val street = "STREET 10"
    }
).select { row ->
    Address(
        row.asInt("address_id")!!,
        row.asString("street")!!,
        row.asInt("version")!!
    )
}
val list: List<Address> = db.runQuery(query)

The above code will issue the following SQL:

select * from address where street = ?

The code in the link may be helpful:

The English version of the documentation is currently under construction and will be available in a month or two.
Questions are always welcome.😃
