The goal of this page is to help Gaia users to prepare and check their ADQL queries on the 2nd Gaia Data Release scheduled for the 25th of April 2018.
With this web service, do not expect to get any glimpse of Gaia DR2 data before the official release. This service only checks the syntax and the schema/table/column names.
When selecting a target TAP service (i.e. Gaia Archive), all their custom ADQL functions are immediately loaded and recognised during the query validation.
The parser and the DR2 data-model used in this validator are based on the TAP service of ARI and should not be much different from what will be released on the 25th of April 2018. However, there is no guarantee that they will be the same in the TAP service of other institutes (e.g. ESAC).
You can also really run your ADQL queries (with a slightly different data-model) on a simulation of Gaia DR2. See gdr2mock at GAVO data center.
If you encounter any problem or have any question, do not hesitate to contact the administrator of this service.
Check a query ONLY on the Gaia-DR2 tables.
