正在使用nebula的3.5.0版本,发现了一个match查询悬挂边的问题,手册说明:目前 MATCH 语句无法查询到悬挂边。但是,match 语句带limit可以查出悬挂边。
情况是左边的点不存在,右边的点存在 ,边类型为chufa_gee
这是相关语句及对应结果
MATCH ()-[r:chufa_gee]->() RETURN r -- 显示无数据(No Data)
MATCH ()-[r:chufa_gee]->() RETURN r limit 10 -- 显示10条查询数据
MATCH (s)-[r:chufa_gee]->() RETURN r limit 10 -- 显示无数据(No Data)
MATCH ()-[r:chufa_gee]->(d) RETURN r limit 10 -- 显示10条查询数据
MATCH (s)-[r:chufa_gee]->(d) RETURN r limit 10 -- 显示无数据(No Data)
