15. Querying your Data
Cypher Query Language

16. Basic Query: Who do people report to?

17. Basic Query: Who do people report to?
MATCH
(e:Employee)<-[:REPORTS_TO]-(sub:Employee)
RETURN
e.employeeID AS managerID,
e.firstName AS managerName,
sub.employeeID AS employeeID,
sub.firstName AS employeeName;

28. Step-by-step Creating the Graph
1.Create the core data
2.Create indexes on the data for performance
3.Create the relationships

29. LOADing the Data
//Create customers
USING PERIODIC COMMIT 1000
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/customers.csv" AS row
CREATE (:Customer {companyName: row.CompanyName, customerID:
row.CustomerID, fax: row.Fax, phone: row.Phone});
//Create products
USING PERIODIC COMMIT 1000
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/products.csv" AS row
CREATE (:Product {productName: row.ProductName, productID: row.ProductID,
unitPrice: toFloat(row.UnitPrice)});

30. LOADing the Data
// Create suppliers
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/suppliers.csv" AS row
CREATE (:Supplier {companyName: row.CompanyName, supplierID:
row.SupplierID});
// Create employees
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/employees.csv" AS row
CREATE (:Employee {employeeID:row.EmployeeID, firstName: row.FirstName,
lastName: row.LastName, title: row.Title});

31. LOADing the Data
// Create categories
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/categories.csv" AS row
CREATE (:Category {categoryID: row.CategoryID, categoryName:
row.CategoryName, description: row.Description});
// Create orders
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/orders.csv" AS row
MERGE (order:Order {orderID: row.OrderID}) ON CREATE SET order.shipName =
row.ShipName;

32. Creating the Indexes
CREATE INDEX ON :Product(productID);
CREATE INDEX ON :Product(productName);
CREATE INDEX ON :Category(categoryID);
CREATE INDEX ON :Employee(employeeID);
CREATE INDEX ON :Supplier(supplierID);
CREATE INDEX ON :Customer(customerID);
CREATE INDEX ON :Customer(customerName);

33. Creating the Relationships
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/orders.csv" AS row
MATCH (order:Order {orderID: row.OrderID})
MATCH (customer:Customer {customerID: row.CustomerID})
MERGE (customer)-[:PURCHASED]->(order);
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/products.csv" AS row
MATCH (product:Product {productID: row.ProductID})
MATCH (supplier:Supplier {supplierID: row.SupplierID})
MERGE (supplier)-[:SUPPLIES]->(product);

34. Creating the Relationships
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/products.csv" AS row
MATCH (product:Product {productID: row.ProductID})
MATCH (category:Category {categoryID: row.CategoryID})
MERGE (product)-[:PART_OF]->(category);
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/employees.csv" AS row
MATCH (employee:Employee {employeeID: row.EmployeeID})
MATCH (manager:Employee {employeeID: row.ReportsTo})
MERGE (employee)-[:REPORTS_TO]->(manager);

35. Creating the Relationships
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/orders.csv" AS row
MATCH (order:Order {orderID: row.OrderID})
MATCH (product:Product {productID: row.ProductID})
MERGE (order)-[relation:PRODUCT]->(product)
ON CREATE SET relation.unitPrice = toFloat(row.UnitPrice), relation.quantit
= toFloat(row.Quantity);
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/neo4j-
contrib/developer-resources/gh-pages/data/northwind/orders.csv" AS row
MATCH (order:Order {orderID: row.OrderID})
MATCH (employee:Employee {employeeID: row.EmployeeID})
MERGE (employee)-[:SOLD]->(order);
