我想加入3个表,就像我们在基于主键和外键的mysql中一样。
我可以使用graphql(http://graphql.org/)这样做吗? 我的表结构和graphql查询如下。感谢
query($companyId:String){
Data{
reach{
department {
departmentId
departmentName
description
}
companyDepartment(companyId:$companyId) {
primaryId
departmentId
companyId
createdDate
modifiedDate
modifiedBy
}
company(companyId:$companyId) {
companyId
companyName
}
}
}
}
答案 0 :(得分:1)
你必须打破思维,用Graph方式模型思考:)
类型公司(节点)< - CompanyDepartmentConection(连接边缘的名称) - >输入部门(节点)
基于这个非常有用的article,无论如何我会为你做的,例如。模式
interface Node {
id: ID!
name: String
}
type Company implements Node {
id: ID!
name: String
departmentsConnection: CompanyDepartmentConnection
}
type CompanyDepartmentConnection {
pageInfo: PageInfo!
edges: [CompanyDepartmentEdge]
}
type CompanyDepartmentEdge {
cursor: String!
node: Company
linkedAt: DateTime
}
