OData相关字段选择语法

Question

只是想知道将相关字段添加到select语句的正确语法是什么。示例员工都有一个部门，该部门在Employee表的departmentID字段中设置。如果我想撤回所有员工但只想显示他们的FirstName和DepartmentName，那么OData select语法是什么？我以为它会像http://example.com/odata.svc/Employees？$ select = FirstName，+ Department.DepartmentName

Answer 1

语法为：http://mywebsite.com/odata.svc/Employees?$select=FirstName,Department/DepartmentName&$expand=Department

Stack Overflow的OData API的相关（工作）示例如下： http://odata.stackexchange.com/stackoverflow/atom/Users?$select=DisplayName,Badges/Name&$expand=Badges
