- SQL Basics: Learn X in Y minutes -> this is a helpful reference for SQL syntax when you run into it. You do not need to write SQL for Django because the Django ORM does it for you, and it does it well. The Django docs often illustrate queries made by the ORM using SQL syntax, however, and you will find it helpful in your job to know the basics.
