Support in Odata4 for the Partner NavigationProperty attribute -------------------------------------------------------------- Key: TEIID-4298 URL: https://issues.jboss.org/browse/TEIID-4298 Project: Teiid Issue Type: Enhancement Components: OData Affects Versions: 9.0 Reporter: Mirco Marchitiello Assignee: Ramesh Reddy Labels: alpha2 Fix For: 9.2 in Teiid 9.0 it would be useful to create a bidirectional link between tables, like in odata2 for example: <EntityType Name="Product"> <Key> <PropertyRef Name="ProductID"/> </Key> <Property Name="ProductID" Type="Edm.Int32" Nullable="false" p5:StoreGeneratedPattern="Identity"/> <Property Name="ProductName" Type="Edm.String" Nullable="false" MaxLength="40"/> <Property Name="SupplierID" Type="Edm.Int32"/> <Property Name="CategoryID" Type="Edm.Int32"/> <Property Name="QuantityPerUnit" Type="Edm.String" MaxLength="20"/> <Property Name="UnitPrice" Type="Edm.Decimal" Precision="19" Scale="4"/> <Property Name="UnitsInStock" Type="Edm.Int16"/> <Property Name="UnitsOnOrder" Type="Edm.Int16"/><Property Name="ReorderLevel" Type="Edm.Int16"/> <Property Name="Discontinued" Type="Edm.Boolean" Nullable="false"/> <NavigationProperty Name="Category" Type="NorthwindModel.Category" Partner="Products"> <ReferentialConstraint Property="CategoryID" ReferencedProperty="CategoryID"/> </NavigationProperty> <NavigationProperty Name="Order_Details" Type="Collection(NorthwindModel.Order_Detail)" Partner="Product"/> <NavigationProperty Name="Supplier" Type="NorthwindModel.Supplier" Partner="Products"> <ReferentialConstraint Property="SupplierID" ReferencedProperty="SupplierID"/> </NavigationProperty> </EntityType> <EntityType Name="Category"> <Key> <PropertyRef Name="CategoryID"/> </Key> <Property Name="CategoryID" Type="Edm.Int32" Nullable="false" p5:StoreGeneratedPattern="Identity"/> <Property Name="CategoryName" Type="Edm.String" Nullable="false" MaxLength="15"/> <Property Name="Description" Type="Edm.String" MaxLength="max"/> <Property Name="Picture" Type="Edm.Binary" MaxLength="max"/> <NavigationProperty Name="Products" Type="Collection(NorthwindModel.Product)" Partner="Category"/> </EntityType> It seems that the two tables are related through NavigationProperty and Partner In fact I can see all the Categories of a certain Product http://services.odata.org/V4/Northwind/Northwind.svc/Products(10)/Category or viceversa the products of a certain Category http://services.odata.org/V4/Northwind/Northwind.svc/Categories(8)/Products While in Teiid using odata2 this works just by creating a FK from one table to the other one, with odata4 this does not happen
