Astronomical Data Query Language (ADQL) is a language for astronomical data query based on SQL 92.[1]
Overview
ADQL is a specialized variant of the SQL query language adapted for accessing the astronomical datasets of the virtual observatory.[2]
Language
ADQL is a query language that allows data to be retrieved but provides no facilities to update that data. It has a single command, the select statement, which is designed to perform as the select statement in the SQL language.
Implementations
ADQL is implemented in packages such as TOPCAT.[3]
