RH Bugzilla Integration updated TEIID-4298:
-------------------------------------------
Bugzilla References:
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
