SQL 2023 standard adds Property Graph Queries (SQL/PGQ)
published on 2023/04/14
A whole new part 16 was added to the SQL standard, titled “Property Graph Queries (SQL/PGQ)”. (Including this new part, there are now 11 active parts of SQL (ISO/IEC 9075). The part that most people know as the core language is part 2.) This allows data in tables to be queried as if it were a graph database.
This is really interesting. Let's see how soon this standard gets implemented by mainstream RDBMS.
