 1. Postgres CTEs & Window Functions
 
+   Prisma is a great ORM, but sometimes you need to go native and write raw SQL to perform complex calculations or queries.
+
+   ### Common Table Expressions (CTEs)
+
+   - "mini temp tables" with selected data that you can query in subsequent selects
+   - break down very large queries into management steps
+   - the `WITH`
+   - WITH provides a way to write auxiliary statements for use in a larger query. These statements, which are often referred to as Common Table Expressions or CTEs, can be thought of as defining temporary tables that exist just for one query.
+   - https://www.postgresql.org/docs/15/queries-with.html
+   - Extra credit `RECURSIVE` and `UNION` queries
+
    ### Window Functions
 
    - Window functions provide the ability to perform calculations across sets of rows that are related to the current query row
