Welcome to the PyADQL Documentation!

PyADQL parses ADQL queries -- the IVOA-standardized query language used by astronomical TAP services (Gaia, SIMBAD, VizieR, ...) -- into a typed Python abstract syntax tree.

This document contains all the information you need to understand and use PyADQL: start with Introduction for the big picture, Tutorial for a hands-on walkthrough, and Operation Manual / Reference Manual for day-to-day usage. For a deep dive into the AST returned by parse_adql(), see the AST guided tour.
