MATCH (p1:Provider)-[s:SHARED]-(p2:Provider)
WHERE p1.id<p2.id and (p1.pcp=0 or (p1.pcp=1 and p2.pcp=0))
WITH p1, p2, count(distinct s.mbrid) as cnt
WHERE cnt>1
RETURN p1, p2, cnt;

+------------------------------------------------------------------------------------------------------+
| p1 | p2 | cnt |

我需要的輸出是在下面的格式。請注意，標識爲3的節點不在下面列出，因爲它不在輸出中。此外，輸出節點索引0,1,2和鏈接使用
{
"nodes" : [
{
"specialty" : "Cardiology",
"pcp" : 0
},
{
"specialty" : "Internal Medicine",
"pcp" : 1
},
{
"specialty" : "Radiology",
"pcp" : 0
}
],
"links" : [
{
"source" : 0,
"target" : 1,
"value" : 3
},
{
"source" : 0,
"target" : 2,
"value" : 4
}
]
}
我將不勝感激任何輸入/指示如何創建此。
