SQLite 查询解释器SQLite Query Explainer
Simon Willison 受 Julia Evans 关于学习运行 SQLite 的文章启发，开发了一款交互式的 SQLite Query Explainer 工具。该工具旨在帮助开发者更好地理解 SQLite 查询计划，解决“读懂查询计划”这一常见痛点。它通过 Fable 构建并提供交互式解释功能，降低了数据库性能调优的门槛。这为需要优化 SQLite 查询但缺乏底层执行计划分析经验的开发者提供了实用帮助。

Tool SQLite Query Explainer — Run SQL queries against a SQLite database in your browser and see exactly how SQLite executes them: the tool runs your query, then annotates every line of both `EXPLAIN QUERY PLAN` and the low-level `EXPLAIN` bytecode output with plain-English descriptions of what the query planner and virtual machine are doing.
Julia Evan's, in Learning a few things about running SQLite:
Maybe one day I’ll learn to read a query plan.
Big same.... which inspired me to have Fable build this interactive explain tool, which runs SQLite in Python in Pyodide in Web Assembly in the browser and adds a layer of explanation to the results of both EXPLAIN and EXPLAIN QUERY PLAN.
Approach with caution, since I don't know enough about SQLite query plans to verify the results myself, but it seems cromulent enough to me.
