Re: korma, and sql dsls, I've been moving between korma, honeysql, and raw sql, without being satisfied with any of them. Desirable traits of the db layer in my problem domain are 1) eliminating boilerplate (e.g. setting up default keys, and indexes, and performing standard joins across relations), 2) isolating view layers from data access layers (so the view doesn't need to know if a subselect or a join is required to span some relation, for example), 3) ability to progressively optimize by dropping back to sql when required, 4) ability to safely expose a general purpose query API over the data.
korma eliminates a very, very small part of the boilerplate. It's almost not worth the effort. Falling back to raw sql smoothly is difficult in korma, and I've had to drop it entirely in places where I need performance. Honeysql eliminates no boilerplate, but representing queries with data structures does make it easy to expose a sql-like query API with db firewalling (by matching on the incoming structure). Korma appears to also represent queries as data structures, but it's not part of the documented API. You have to reverse-engineer it, and I expect it's subject to change.
