DELETE EDGE

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，详情请参见管道符。

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DELETE VERTEX。

!!! Note

目前还不能保证操作的原子性，如果发生故障请重试。

语法

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

示例

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

# 结合管道符，删除符合条件的边。
nebula> GO FROM "player100" OVER follow \
        WHERE follow._dst == "team204" \
        YIELD follow._src AS src, follow._dst AS dst, follow._rank AS rank \
        | DELETE EDGE follow $-.src->$-.dst @ $-.rank;
