Writing a SQL database from scratch in Go: 1. SELECT, INSERT, CREATE and a REPL

This technical article is the first part of a series detailing how to build a rudimentary SQL database from scratch using the Go programming language. It covers implementing a lexer and parser to handle CREATE, INSERT, and SELECT statements, creating an in-memory backend for TEXT and INT data types, and building a Read-Eval-Print Loop (REPL) for interactive querying. The post includes code examples and explanations of core parsing concepts.
