Database Functions

db.version()

Returns the database version string.

GQL
RETURN db.version()

db.license()

Returns license information.

GQL
RETURN db.license()

db.plugins()

Returns a list of loaded plugins.

GQL
RETURN db.plugins()

db.stats()

Returns statistics of the current graph, including node/edge counts, label counts, and properties.

GQL
RETURN db.stats()

The returned record contains the following fields:

Field	Type	Description
`graphName`	`STRING`	Name of the current graph
`nodeCount`	`INT`	Total number of nodes
`edgeCount`	`INT`	Total number of edges
`unlabeledNodeCount`	`INT`	Number of nodes without labels
`unlabeledEdgeCount`	`INT`	Number of edges without labels
`labelCounts`	`RECORD`	Node counts per label (e.g., `{"Paper": 3}`)
`edgeLabelCounts`	`RECORD`	Edge counts per label (e.g., `{"Cites": 2}`)
`nodePropertyStats`	`RECORD`	Node property counts per label (e.g., `{"Paper": {"title": 3, "score": 3}}`)
`edgePropertyStats`	`RECORD`	Edge property counts per label (e.g., `{"Cites": {"weight": 2}}`)
`unlabeledNodePropertyStats`	`RECORD`	Property counts for unlabeled nodes
`unlabeledEdgePropertyStats`	`RECORD`	Property counts for unlabeled edges

GQL
LET stats = db.stats()
RETURN stats.nodeCount AS nodes, stats.edgeCount AS edges

db.overview()

Returns the current graph overview with label counts and edge patterns.

GQL
RETURN db.overview()

The returned record contains:

Field	Type	Description
`labelCounts`	`LIST`	List of `{label, count, type}` records for each node/edge label
`edgePatterns`	`LIST`	List of `{fromLabel, edgeLabel, toLabel, edgeCount}` records describing connection patterns

db.nodeLabels()

Returns all node labels in the current graph.

GQL
RETURN db.nodeLabels()

db.edgeLabels()

Returns all edge labels in the current graph.

GQL
RETURN db.edgeLabels()

db.labelProperty()

Returns the properties defined for each label in the current graph. For closed graphs, returns schema-defined properties. For open graphs, discovers properties by scanning data.

GQL
RETURN db.labelProperty()

The returned record maps each label name to a {type, properties} record, where type is "node" or "edge" and properties is a list of property names.

db.reloadStats()

Rebuilds statistics from storage for the current graph.

GQL
RETURN db.reloadStats()
