Django - Subquery, OuterRef and Exists objects for Database SQL Subqueries
Показать описание
In this video, we'll look at Subqueries in Django. We'll see how to use subqueries in annotations, filter statements and with the Exists subclass.
Subqueries can be useful for performing these operations on complex related information, and can exist in the SELECT and WHERE expressions (among others) of an SQL SELECT Query.
