DDL is boring. DML/DQL are the power of SQL and the relational model. They are what enables ad-hoc querying that the schema designer had never considered. As soon as you do anything other than select * the composite types defined in DDL aren't as important. I was suggesting that the immutable part of FP (which is most of it) has a lot of similarity with relational querying, which is very successful in the real world.
