SQLGLOT
SQL parser, transpiler, and optimizer
MIT
ABOUT
AI applications that generate SQL — from natural-language-to-SQL agents to analytics copilots — produce queries that must run correctly across many warehouses, but each database has its own dialect quirks. SQLGlot parses SQL into a unified AST, transpiles between 20+ dialects (BigQuery, DuckDB, Postgres, Snowflake), and validates generated queries before execution, so LLM-generated SQL can be normalized, checked, and executed reliably on any engine.
INSTALL
pip install sqlglotINTEGRATION GUIDE
1. Validate and transpile LLM-generated SQL from a text-to-SQL agent to the target warehouse dialect before execution
2. Normalize user-written queries into a canonical AST for semantic analysis, redaction, or schema-aware rewriting
3. Optimize slow queries by inspecting the parsed tree, extracting table lineage, and applying predicate pushdown
