Learn SQLite in Neovim: Data Types — INTEGER, REAL, TEXT & typeof() | Episode 4

Understand how SQLite stores your data! In this episode, we explore INTEGER, REAL, TEXT, the typeof() function, and SQLite's surprising flexible typing. We build a product catalog and inspect each column's storage type with typeof(). Then we discover that SQLite lets you put text in a number column — and what that means for your data.
