Procedures

Procedures are invoked using the syntax:

GRAPH.QUERY social "CALL db.labels()"

Or the variant:

GRAPH.QUERY social "CALL db.labels() YIELD label"

YIELD modifiers are only required if explicitly specified; by default the value in the ‘Yields’ column will be emitted automatically.

Procedure	Arguments	Yields	Description
db.labels	none	label	Yields all node labels in the graph.
db.relationshipTypes	none	relationshipType	Yields all relationship types in the graph.
db.propertyKeys	none	propertyKey	Yields all property keys in the graph.
db.indexes	none	label, properties, types, options, language, stopwords, entitytype, status, info	Yield all indexes in the graph, denoting whether they are exact-match or full-text and which label and properties each covers and whether they are indexing node or relationship attributes.
db.constraints	none	type, label, properties, entitytype, status	Yield all constraints in the graph, denoting constraint type (UNIQIE/MANDATORY), which label/relationship-type and properties each enforces.
db.idx.fulltext.createNodeIndex	label, property [, property …]	none	Builds a full-text searchable index on a label and the 1 or more specified properties.
db.idx.fulltext.drop	label	none	Deletes the full-text index associated with the given label.
db.idx.fulltext.queryNodes	label, string	node, score	Retrieve all nodes that contain the specified string in the full-text indexes on the given label.
algo.pageRank	label, relationship-type	node, score	Runs the pagerank algorithm over nodes of given label, considering only edges of given relationship type.
algo.BFS	source-node, max-level, relationship-type	nodes, edges	Performs BFS to find all nodes connected to the source. A max level of 0 indicates unlimited and a non-NULL relationship-type defines the relationship type that may be traversed.
dbms.procedures()	none	name, mode	List all procedures in the DBMS, yields for every procedure its name and mode (read/write).
