This basic use case doesn't seem to be catered for in the DAO guide. I can see how to do it with a full 'Entity' for each string, each with its ID and reference etc, but this is unnecessarily heavy - just a table with 'parentId, string' should be all that's necessary to implement the one-to-many relationship.
I can't believe Exposed has missed this out...

If you'd like to make sql queries on them, then you need a column. As it's one-to-many, you need two tables and two entities.
Or you do not like the fact that you need to use it as:
parent.children.map { it.strCol }2 Views
