## What it is
SQLGlot is a dependency-free Python SQL parser, transpiler, optimizer, and execution engine supporting 30+ SQL dialects such as DuckDB, Snowflake, BigQuery, and Spark. It enables formatting, translating, analyzing, and programmatically building SQL via expression trees.

## Use cases
- translate SQL between dialects like Snowflake and BigQuery
- format and pretty-print SQL queries
- parse SQL into an AST for analysis
- detect SQL syntax errors and dialect incompatibilities
- programmatically build or modify SQL queries
- optimize SQL queries
- execute SQL with a pure-Python engine

## When to choose
- you need dialect-agnostic SQL parsing or translation in Python
- you want a zero-dependency, pure-Python SQL tool
- you need to analyze, lint, or rewrite SQL programmatically

## When to avoid
- you need a full production database engine rather than parsing/transpiling
- you need a non-Python runtime

## Facets
- artifact type: library
- maturity: stable
- function: parser, compiler, developer-tools
- domain: databases, parsers, developer-tools
- platform: python, cross-platform
- tags: sql, transpiler, sql-dialects, ast, query-optimization, sql-formatting, query-engine, data-engineering
