DELETE VERTEX¶

DELETE VERTEX <vid> [, <vid> ...]

Use DELETE VERTEX to delete vertices and the related incoming and outgoing edges of the vertices. The DELETE VERTEX statement deletes one vertex or multiple vertices at a time. You can use DELETE VERTEX together with pipe. For more information about pipe, see Pipe operator.

Examples¶

nebula> DELETE VERTEX "team1";

This query deletes the vertex whose ID is "team1".

nebula> GO FROM "player100" OVER serve YIELD serve._dst AS id | DELETE VERTEX $-.id;

This query shows that you can use DELETE VERTEX together with pipe.

Nebula Graph traverses the incoming and outgoing edges related to the vertices and deletes them all. Then Nebula Graph deletes information related to the vertices.
