试图在cypher sql中构建嵌套查询来查找grossale，distinctcustomer和salesreach的销售额，并且无法将列1的值作为输入传递给另一列-任何帮助都将不胜感激。
在这里

MATCH (n:Commercial)
WITH (n) AS grosssales, count(n) AS distinctcustomer, 
  n.customer_id AS customer, ### grouping by customer_id ###
  grosssale / distinctcustomer AS salesreach
RETURN grossale, distinctcustomer, salesreach, customer_id

字符串
尝试了WITH子句，但没有喜悦，将感谢任何帮助，在纠正密码语法。

MATCH (n:Commercial) 
WITH count(n) AS grosssales 
MATCH (c:Commercial) 
WITH grosssales,count(c) AS distinctcustomer, c.customer_id AS customer, tofloat(grosssales/count(c)) AS salesreach 
RETURN imp AS grosssales, distinctcustomer, customer, salesreach

可以使用新的COUNT subquery（neo4j 5.0+中）来计算Commercial节点的总数，从而简化查询。尽管COUNT()是一个聚合函数，但customer子查询不是--因此它不受customer分组键的影响。

MATCH (c:Commercial) 
WITH COUNT{ (:Commercial) } AS grosssales, COUNT(c) AS distinctcustomer, c.customer_id AS customer
RETURN grosssales, distinctcustomer, customer, TOFLOAT(grosssales/distinctcustomer) AS salesreach
