Or:
(dsl/entities #(str/replace % #"-" "_")
(j/insert! db table {:created-by 1, :name "test"}))
(and I'd make that a named function and wrap any blocks of DB code in
dsl/entities).

Hmm, insert! should return either a sequence of just generated keys or
a sequence of row change counts. Not sure how you're getting the
translated column names back - can you show your exact code?

And specifically the db object does not take part in the SQL
generation which is why this cannot work (I discussed this at length
in another thread).

You would never need :transaction? unless you had some very specific,
strange edge case so you can just ignore it.
The implementation uses it and there have been some specific edge
cases people have requested for specific DBs where they've needed to
control transactions at that level.
