DROP

The DROP function deletes a graph and all of its triples.

DROP Syntax

Use the following syntax to delete graphs and their triples using the DROP function.

DROP [ SILENT ] GRAPH <graph> | DEFAULT | NAMED | ALL

The optional SILENT keyword tells AnzoGraph not to return an error if an error occurs.

Option	Description
DROP GRAPH <graph>	Deletes the named graph.
DROP DEFAULT	Since a graph database must always have a default graph, the DROP DEFAULT operation deletes the triples from the default graph; it does not remove the graph. DROP DEFAULT is synonymous with CLEAR DEFAULT.
DROP NAMED	Deletes all of the named graphs in the database.
DROP ALL	Deletes all of the graphs and their triples from the database. Since the default graph cannot be removed, the triples from the default graph are deleted but the default graph remains.
