Selda: A Haskell SQL Library
What is Selda? Selda is an EDSL — an embedded domain-specific language — for defining, querying and modifying relational databases from Haskell. The same type-safe Selda query can be executed unmodified on either PostgreSQL or SQLite, making Selda ideal for prototyping as well as for taking the step from prototype to real application. Through its monadic interface, Selda supports writing queries i
Sum Types In SQL
Algebraic datatypes are a powerful feature of functional programming languages. By combining the expressive power of “and” and “or,” we can solve all kinds of problems cleanly and elegantly. SQL databases represent product types – “and” – extremely well - a SQL table can correspond easily and directly to a product type where each field in the product type can fit in a single column. On the other h
