Dear VO Community,<br>
<br>
The Data Access Layer working group invite you to review the
Proposed Recommendation on ADQL v2.1.<br>
<br>
The RFC period will run from 25 April 2023 to 20 June 2023.<br>
<br>
ADQL is a standard query language based on SQL and adapted for
astronomical purpose. The proposed minor revision fixes some parts
of ADQL-2.0 and adds the notion of optional features which lets add
some needed SQL features as well as new interesting astronomical
functions.<br>
