Learn SQL Using PostgreSQL: From Zero to Hero
Learn SQL Using PostgreSQL: From Zero to Hero
Learning SQL was one of the most valuable skills I learned while building Match. We had one of the largest instances of Microsoft SQL Server in the 90s with millions of records to keep the site running. The better we got at SQL, the better we could make the site work for our users and answers sophisticated questions about our users.

Basic selection statements
Joining multiple tables together
Grouping records to get aggregate data
Inserting, updating and deleting records
Creating tables and indexes
Subqueries to create sophisticated reports

CTE - common table expressions that include recursive queries
Views to simply accessing complex queries
Conditional Expressions for queries
Window functions to combine regular queries with aggregate data
How to work with date, time and intervals
Create SQL Functions to capture complex statements
Create PL/pgSQL Functions that allow programming with if/then and loops
