Cloud Platform Integration has enabled OData V4 adapter with which various OData operations can be done on an OData V4 endpoint.

This blog covers the payload structure for various Data modification operations like

Create
Deep Insert
Update

The table below summarizes some of the primitive types and how each MUST be represented when used in a payload.

Primitive Types	Description	Literal form	Sample in payload
Edm.Boolean	Binary-valued logic	true	true
Edm.Date	Date without a time-zone offset	date’2014-01-03′	2014-01-03
Edm.DateTimeOffset	Date and time with a time-zone offset, no leap seconds	datetimeoffset’2014-01-03T10:00:00Z’	2014-01-03T10:00:00Z
Edm.Decimal	Numeric values with fixed precision and scale	2.345M	2.345M
Edm.Double	IEEE 754 binary64 floating-point number (15-17 decimal digits)	2.029d	2.029d
Edm.Duration	Signed duration in days, hours, minutes, and (sub)seconds	duration’PT0S’	20D5H2S
Edm.Guid	16-byte (128-bit) unique identifier	guid’dddddddd-dddd-dddd-dddd-dddddddddddd’	12345678-aaaa-bbbb-cccc-ddddeeeeffff
Edm.Int16	Signed 16-bit integer	16	16
Edm.Int32	Signed 32-bit integer	32	32

1. Create

To create an entity in a collection, body MUST contain a single valid entity representation.

Properties with Edm type having Collection should have each of its value enclosed within <element> tags.

Request Schema

<EntitySetName>
	<EntityTypeName>
		<PropertyName>PropertyValue</PropertyName>
		<PropertyName>PropertyValue</PropertyName>
		<PropertyName>                            //Property with type Collection of Primitive
			<element>PropertyValue</element>
		</PropertyName>
		<PropertyName>                            //Property with type Collection of Complex

</EntitySetName>

Sample payload for Microsoft hosted V4 service https://services.odata.org/TripPinRESTierService/(S(samplePayload))/

		<FirstName>Russell</FirstName>
		<LastName>Whyte</LastName>

					<CountryRegion>United States</CountryRegion>
					<Region>ID</Region>
				</City>
			</element>
		</AddressInfo>

	</Person>
</People>

2. Deep Insert

A request to create an entity that includes related entities, represented using the appropriate inline representation, is referred to as a “deep insert”.

Request Schema for Deep insert

<EntitySetName>
	<EntityTypeName>
		<PropertyName>PropertyValue</PropertyName>
		<PropertyName>PropertyValue</PropertyName>
		<PropertyName>
			<element>
				<PropertyName>PropertyValue</PropertyName>
				<PropertyName>PropertyValue</PropertyName>
			</element>
		</PropertyName>
		<NavigationPropertyName>        //Navigation Property with type Single Entity 
			<EntityTypeName>
				<PropertyName>PropertyValue</PropertyName>
				<PropertyName>
					<element>PropertyValue</element>
				</PropertyName>				
			</EntityTypeName>
		</NavigationPropertyName>
		<NavigationPropertyName>        //Navigation Property with type collection of Entity 
			<EntityTypeName>
				<PropertyName>PropertyValue</PropertyName>
				<PropertyName>

				<PropertyName>PropertyValue</PropertyName>
				<PropertyName>
					<element>PropertyValue</element>

			</EntityTypeName>
		</NavigationPropertyName>
	</EntityTypeName>
</EntitySetName>

From the below edmx, The Entity “Person” has navigation to BestFriend with target type as a single Person

Entity “Person” also has navigation to Trips which is a collection of Trip.

<EntityType Name="Person">
	<Key>
		<PropertyRef Name="UserName"/>
	</Key>
	<Property Name="UserName" Type="Edm.String" Nullable="false"/>
	<Property Name="FirstName" Type="Edm.String" Nullable="false"/>
	<Property Name="LastName" Type="Edm.String"/>
	<Property Name="MiddleName" Type="Edm.String"/>
	<Property Name="Gender" Type="Microsoft.OData.Service.Sample.TrippinInMemory.Models.PersonGender" Nullable="false"/>
	<Property Name="Age" Type="Edm.Int64"/>
	<Property Name="Emails" Type="Collection(Edm.String)"/>
	<Property Name="AddressInfo" Type="Collection(Microsoft.OData.Service.Sample.TrippinInMemory.Models.Location)"/>
	<Property Name="HomeAddress" Type="Microsoft.OData.Service.Sample.TrippinInMemory.Models.Location"/>
	<Property Name="FavoriteFeature" Type="Microsoft.OData.Service.Sample.TrippinInMemory.Models.Feature" Nullable="false"/>
	<Property Name="Features" Type="Collection(Microsoft.OData.Service.Sample.TrippinInMemory.Models.Feature)" Nullable="false"/>
	<NavigationProperty Name="Friends" Type="Collection(Microsoft.OData.Service.Sample.TrippinInMemory.Models.Person)"/>
	<NavigationProperty Name="BestFriend" Type="Microsoft.OData.Service.Sample.TrippinInMemory.Models.Person"/>
	<NavigationProperty Name="Trips" Type="Collection(Microsoft.OData.Service.Sample.TrippinInMemory.Models.Trip)"/>
</EntityType>
