DELETE EDGE¶
The DELETE EDGE statement deletes one edge or multiple edges at a time. You can use DELETE EDGE together with pipe operators. For more information, see PIPE OPERATORS.
To delete all the outgoing edges for a vertex, please delete the vertex. For more information, see DELETE VERTEX.
Syntax¶
ngql
DELETE EDGE <edge_type> <src_vid> -> <dst_vid>[@<rank>] [, <src_vid> -> <dst_vid>[@<rank>] ...]
Examples¶
ngql
nebula> DELETE EDGE serve "player100" -> "team204"@0;
The following example shows that you can use DELETE EDGE together with pipe operators to delete edges that meet the conditions.
ngql
nebula> GO FROM "player100" OVER follow \
WHERE dst(edge) == "team204" \
YIELD src(edge) AS src, dst(edge) AS dst, rank(edge) AS rank \
| DELETE EDGE follow $-.src->$-.dst @ $-.rank;
