Roadmap de estudos de SQL

Aviso: Muitas vezes detalhes de várias operações podem variar de banco para banco. Em questões onde fiquei em dúvida, este documento segue o funcionamento do PostgreSQL, pois é o banco que conheço melhor.

Pré-requisito: Álgebra Relacional básica

Antes de começar a escrever SQL, você precisa entender o modelo de como um banco de dados relacional funciona. Não precisa se aprofundar muito, mas você precisa entender como que dados e relacionamentos entre eles são representados. (Nota importante: Relacionamento e relação não são a

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link in the table of content jumps at the copy of the answer on this page.
• The link on the answer itself points back at the original post.
