如何在SQL Server 2017中实现图形数据库

所谓图形数据库并不是存储图片的数据库，而是基于“图论”的对象与关系。

只有两种类型的表（点和线）
节点表：节点表定义图模型中的实体。
边缘表：边缘表定义节点表实体之间的连接

查询加MATCH语句

SELECT UsersFol.NickName
FROM Users Users, FlowInfo, Users UsersFol
WHERE MATCH(Users-(FlowInfo)->UsersFol)
AND Users.NickName = 'Camila';

这些查询将向我们显示哪些客户喜欢哪本书以及哪本书排名很高

select Customer.CustName,Books.BookName,CustomerBookRate.RankAmount from Customer,CustomerBookRate,Books
where MATCH (Customer-(CustomerBookRate)->Books)

select Books.BookName,sum(CustomerBookRate.RankAmount) from Customer,CustomerBookRate,Books
where MATCH (Customer-(CustomerBookRate)->Books)
group by Books.BookName
