About this item

A compact, printable snippet pack for reporting and analytics queries for a marketplace database (sellers and listings). Each of the 12 entries has a one-line explanation and a small example you can paste into your editor. The PDF uses a two-column A4 layout designed to sit next to your keyboard, and the same content ships as Markdown so you can search it or drop it into your notes, plus a .sql file with every query. Every SQL example targets PostgreSQL 16.
