## What it is
A Haskell library for parsing and analyzing SQL queries in Vertica, Hive, and Presto dialects into a shared abstract syntax tree. It provides name resolution and analyses such as table/column access, joins, and table lineage.

## Use cases
- parse hive sql queries
- extract table lineage from presto queries
- find which columns a sql query accesses
- analyze joins in vertica sql
- resolve table and column names in sql queries
- build sql query analysis tooling

## When to choose
- you need to parse Vertica, Hive, or Presto SQL dialects
- you want column-level or table-level lineage analysis of SQL queries
- you are building tooling on top of a Haskell SQL AST

## When to avoid
- you need to parse other SQL dialects like MySQL or Postgres
- you need a maintained tool with recent releases
- you are not working in Haskell or cannot integrate with it

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, nlp
- domain: databases, parsers, developer-tools
- platform: cross-platform, cli
- tags: sql-parsing, vertica, hive, presto, haskell, query-analysis, lineage, ast
