需要帮助设计 neo4j 查询

如何解决需要帮助设计 neo4j 查询

这里是 Neo4j 新手。 我已经设置了以下关系

InputStream is = ... // you only need an input stream,no local file
    
DefaultFileSystemManager fsmanager = (DefaultFileSystemManager) VFS.getManager();
        
FileSystemOptions opts = new FileSystemOptions();
FtpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(opts,true);
StaticUserAuthenticator auth = new StaticUserAuthenticator(host,username,password);
         
DefaultFileSystemConfigBuilder.getInstance().setUserAuthenticator(opts,auth);
        
String ftpurl = "ftp://" + host + ":" + port + "/" + folder + "/" + filename;
FileObject remoteFile = fsmanager.resolveFile(ftpurl,opts);
        
try (OutputStream ostream = remoteFile.getContent().getOutputStream()) {
    // either copy input stream manually or with IOUtils.copy()
    IOUtils.copy(is,ostream);
}
        
boolean success = remoteFile.exists();
long size = remoteFile.getContent().getSize();
System.out.println(success ? "Successful,copied " + size + " bytes" : "Failed");

我将最受欢迎的股票作为

Customer - [Buys] -> Stocks

MATCH (n:Customer)-[:BUYS]->(s:Stock) RETURN s,count(distinct n) as cnt order by cnt desc limit 1 属性。

我需要找到两件事。

1. 客户在购买最受欢迎的股票之前和之后买了什么

2. 显示最连续下单的客户 日历月？

对于 pt1：我创建了单独的查询来提取最受欢迎的股票并尝试以下选项。

Buy relation have Quantity,unit price and invoice date

我想这样做，但它不起作用

Match (cust:Customer)-[b:BUYS]->(s:Stock)
where b.inInvoiceDate < (match (p)-[b1:Buys]->(s1:Stock {StockCode='18102'}) return b1.InvoiceDate) limit 10 --This fails

有没有像在 sql 世界中那样我可以创建临时表并引用它们的方法？
