On creating a new account I get

exposed version 0.34.1
mysql-jdbc connector

Not sure yet where I'm going wrong or if it's a bug.

Inserting a Name works fine
But inserting an Account throws

AccountsTable.id is not in record set

Behaviour current solution tables look fine column registration order affecting inserts.

Oh, it was a very tricky bug! Thank you so much that you find out that columns order is matter (btw it fails only on SQLite and MySQL).

I was able to fix it in the master and will release the fix on the week.

A few things to make your code a bit less verbose - use predefined classes for IntTables and Entities (also public is a default visibility scope in Kotlin and can ba omitted):

class Names(id: EntityID<Int>) : IntEntity(id) {
    var first: String by NamesTable.first

    var second: String by NamesTable.second

    operator fun invoke(): Name = transaction {
        Name(
            id = this@Names.id.value,
            first = first,
            second = second
        )
    }

    companion object : IntEntityClass<Names>(NamesTable) {
        fun new(name: Name): Names = transaction {
            new {
                first  = name.first
                second  = name.second
            }
        }
    }
}

class Accounts(  id: EntityID<Int>)  :  IntEntity(id) {
    var name: Names by  Names referencedOn  AccountsTable.name

    companion object : IntEntityClass<Accounts>(AccountsTable) {
        public fun new(account: Account): Accounts = transaction {
            new {
                name  =  Names.new(account.name)
            }
        }
    }
}

object NamesTable : IntIdTable("names_table") {
  val first: Column<String> = varchar("first",50)
  val second: Column<String> = varchar("second",50)
}

object AccountsTable : IntIdTable("accounts_table") {
  val name: Column<EntityID<Int>> = reference("name", NamesTable)
}

Thanks a lot. Working on a Dao and Table annotations processing thus the strict code requirements from Kotlin poet (public) :) Using the Entity to just have a unified code generation for the first phase will definitely consider using the generated ones once the code base is a bit more stable.

I created rebo to avoid having to write some of the boilerplate code. Would appreciate any review.

Works with KSP for code generation performance. Feedback would be appreciated.
