SQL Basics Cheat Sheet (Printable PDF)

For the query you write once a quarter and forget in between.

Use it when: you need one SELECT with a JOIN and can't remember the syntax, when a COUNT returns the wrong number, when you're shaping data by hand.

On the sheet: SELECT, WHERE, JOINs, aggregates and data manipulation.

Not on it: database administration and tuning.
