Supported optional GQL features

This page lists the optional GQL features Cypher^® is either fully or partially conformant with.

Optional GQL features are assigned a feature ID code. These codes order the features in the table below.

GQL Feature ID Description Comment

GQL Feature ID	Description	Comment
GA06	Value type predicates
GF01	Enhanced numeric functions	Supported functions: `abs()`, `floor()`, and `sqrt()`.
GF02	Trigonometric functions	Supported functions: `acos()`, `asin()`, `atan()`, `cos()`, `cot()`, `degrees()`, `radians()`, and `tan()`.
GF03	Logarithmic functions	Supported functions: `exp()` and `log10()`.
GF05	Multi-character trim functions	Supported functions: `ltrim()` and `rtrim()`.
GO35	Quantified paths
GO36	Quantified relationships
GO74	Label expressions: wildcard label
GQ01	`USE` graph clause	Cypher’s `USE` clause supports static graph references (e.g. `USE myComposite.myGraph`)and dynamic graph references (e.g. `USE graph.byName(<expression>)`). However, Cypher does not support GQL’s full graph reference syntax. For example, GQL’s graph reference values `CURRENT_GRAPH` and `CURRENT_PROPERTY_GRAPH` cannot be used in Cypher.
GQ03	Composite query: `UNION`
GQ13	`ORDER BY` and page statement: `LIMIT`	Cypher requires using the `WITH` clause, which GQL does not.
GV50	List value types
GV55	Path value types
GV66	Open dynamic unions
GV67	Closed dynamic unions
GV70	Immaterial value types: null type support (`NULL`)
GV71	Immaterial value types: empty type support (`NOTHING`)

GA06

Value type predicates

GF01

Enhanced numeric functions

Supported functions: abs(), floor(), and sqrt().

GF02

Trigonometric functions

Supported functions: acos(), asin(), atan(), cos(), cot(), degrees(), radians(), and tan().

GF03

Logarithmic functions

Supported functions: exp() and log10().

GF05

Multi-character trim functions

Supported functions: ltrim() and rtrim().

GO35

Quantified paths

GO36

Quantified relationships

GO74

Label expressions: wildcard label

GQ01

USE graph clause

Cypher’s USE clause supports static graph references (e.g. USE myComposite.myGraph)and dynamic graph references (e.g. USE graph.byName(<expression>)). However, Cypher does not support GQL’s full graph reference syntax. For example, GQL’s graph reference values CURRENT_GRAPH and CURRENT_PROPERTY_GRAPH cannot be used in Cypher.

GQ03

Composite query: UNION

GQ13

ORDER BY and page statement: LIMIT

Cypher requires using the WITH clause, which GQL does not.

GV50

List value types

GV55

Path value types

GV66

Open dynamic unions

GV67

Closed dynamic unions

GV70

Immaterial value types: null type support (NULL)

GV71

Immaterial value types: empty type support (NOTHING)

Cypher and GQL sometimes name functions differently and, as a result, several Cypher functions offer the same (or very similar) functionality to their GQL counterpart, yet they are not conformant with GQL. For more information, see the page Optional GQL features and analogous Cypher.
