DELETE EDGEGraph

DELETE EDGE语句可以删除边。一次可以删除一条或多条边。用户可以结合管道符一起使用，详情请参见Graph。

如果需要删除一个点的所有出边，请删除这个点。详情请参见 Graph。

语法Graph

DELETE EDGE <edge_type> <src_vid> -> <dst_vid>[@<rank>] [, <src_vid> -> <dst_vid>[@<rank>] ...]

Caution

如果不指定 rank，则仅仅删除 rank 为 0 的边。需要删除所有的 rank，见如下示例。

示例Graph

nebula> DELETE EDGE serve "player100" -> "team204"@0;

# 结合管道符，删除两点之间同类型的所有rank的边。
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;
