SQL is a declarative language. Cypher is somewhat SQL-like, also declarative language which exists to make the expression of graph queries with predicates over nodes and edges easier to express.
Thank you for the correction. You are correct, SQL is a declarative language. It would've been more accurate for me to refer to Cypher as 'a more expressive declarative query language' (specifically for the graph database paradigm) than a typical SQL-like query language.
