您好，很高兴看到您的项目，我使用您的方法把数据导入neo4j数据库

但是我访问 localhost:7474,并没有看到知识图谱，这是怎么回事呢?

请您多指教一下，谢谢!

CASE doesn't work well with null. This works as expected and prints 'works':

WITH 2 AS name
RETURN CASE name
    WHEN 2 THEN 'works'
    WHEN null THEN "doesn't work"
    ELSE 'something went wrong'
END

If we swap the first case from 2 to 3. It should print 'something went wrong', but instead it prints "doesn't work":

WITH 2 AS name
RETURN CASE name
    WHEN 3 THEN 'works'
