We gave him 4 options to save taxes

He ended up paying ZERO tax. Here's all about those 4 options🧵👇

SQL has levels to it:

- level 1
SELECT, FROM, WHERE, GROUP BY, HAVING, LIMIT

Master these basic keywords and you’ll be well on your way to mastering SQL.

- level 2
Mastering JOINs:
Most common JOINs: INNER and LEFT
Less common JOINs: FULL OUTER
Joins you should avoid almost always: RIGHT and CROSS JOIN

Mastering common table expressions (CTEs).

The WITH keyword defines a CTE which you can imagine as a “variable” that you can query later.

Using variables like this you can master algorithm techniques like recursion, breadth first search and more!

CTEs also make your SQL much more readable and make your coworkers hate you less compared to nested sub queries.

- level 3
Mastering window functions

Window functions have 3 pieces:

The function (i.e. SUM, RANK, AVG)
The over clause to start the window
The window definition which has 3 pieces:
- how to split the window up with PARTITION BY
- how to order the window with ORDER BY
- how to restrict the window size with ROWS clause (useful for rolling monthly averages)

Understand RANK vs DENSE_RANK vs ROW_NUMBER, I have been asked this in interviews a million times.

- level 4
You understand table scans, b-tree indexes, and partitioning schemes to increase performance.

Doing something like COUNT(CASE WHEN) is much better than doing multiple queries with a UNION ALL. UNION ALL is terrible for all sorts of reasons that I don’t want to get into in this post.

B-trees indexes allow for efficient scanning of data in the WHERE clause.

Use explain plans to understand if an index is actually being used or not!

Partitioning is similar to indexes except it’s a “poor mans” index. It just keeps data in specific folders and skips the folders that don’t include the data I question.

What else did I miss for mastering SQL?
