Property graphs enjoy an ever-increasing popularity in applications that deal with connected components of all varieties; e.g., social networks, fraud detection, etc. Today there are a number of stand-alone languages used with Property Graphs including Apache Tinkerpop Gremlin, Neo4j Cypher, Tigergraph GSQL and Oracle PGQL as well as a proposal for another stand-alone language under consideration by ISO, GQL. It is well known that SQL is the most widely used database language and is the language of choice for database application developers. To support graph creation and querying, the ISO SQL 202x standard will include new extensions for graph databases, SQL/PGQ. We will show how SQL/PGQ will integrate with SQL to allow users to define property graphs based on data stored in existing tables and to query those graphs. The query part will use a combination of familiar SQL as well as a new built-in operator, which significantly simplifies typical graph queries compared to existing SQL.
