This specification discloses a method. The method includes: when a received match statement includes a filtering condition of a path pattern, a node that matches a path in the path pattern is queried from all nodes in the graph database based on the path, to obtain a first node set. A node that meets a matching condition in the match statement is determined from all the nodes in the graph database based on the matching condition. For each node that meets the matching condition, whether the node falls within the first node set is determined. Whether the node belongs to a query result of the match statement is determined based on a determining result. Traversing, based on the path pattern, a path of a node that matches the match statement can be simplified as matching between a node and a node set.
A data query method, wherein the data query method is applied to a graph database, and the method comprises:
A non-transitory computer-readable storage medium, having stored therein instructions that, when executed by a processor of a computing device, cause the processor to:
