查询两个顶点ID之间的边缘ID

Question

我有User个顶点和friends边缘。我知道有两个用户是朋友，其中一个想要与另一个用户取消联系。我怎么能删除给定顶点之间的边缘？

到目前为止，运行 DELETE EDGE FROM :player1 TO :player2 WHERE @class = "friends" 和 DELETE EDGE FROM :player2 TO :player1 WHERE @class = "friends"（使用适当的params ofc。）以确保删除它对我来说很好但是感觉优雅不够。

您应该可以在一个查询中执行此操作：

 DELETE EDGE friends FROM [:player1, :player2] TO [:player1, :player2]

如果您还有从顶点到自身的边（例如，从player1到player1）并且您不想删除它们，则可以添加条件：

 DELETE EDGE friends FROM [:player1, :player2] TO [:player1, :player2]
 WHERE out <> in
