The following example shows how to remove a contact record to the account contact_customer_accounts collection where the contact contactid value is cf9eaaef-f718-ed11-b83e-00224837179f. The following example shows how to add a role record to the systemuser systemuserroles_association collection which is a many-to-many relationship. The following example shows how to add a contact record to the account contact_customer_accounts collection which is part of a one-to-many relationship. ![]() ![]() ![]() This section will describe how to work with collection-valued navigation properties with any type of relationship. There is no difference how you work with any of these types of relationships while using collection-valued navigation properties. For one-to-many and many-to-one relationships, the table one the 'One' side will have a collection-valued navigation property. With OData, both sides of a many-to-many relationship will have collection-valued navigation properties. Using collection-valued navigation properties Note: You must use an absolute URL when setting the value for remove the reference, you can also use this DELETE request: You can use the following PUT request to set the value of the parentcustomerid_account single-valued navigation property: There are other ways to achieve the same results described above with single-valued navigation properties. More information: Basic update Other methods You can simply use the name of the single-valued navigation property: When disassociating in this manner, you don't need to include the annotation. If you want to disassociate, you can simply set the value to null. Disassociate with a single-valued navigation property OData-EntityId: /api/data/v9.2/contacts(cf9eaaef-f718-ed11-b83e-00224837179f)Īs described in Associate table rows on create, new records can also be associated with existing records in the same way. Associate with a single-valued navigation propertyįor example, to associate a contact record to an account using the parentcustomerid_account single-valued navigation property: The easiest and most common way to do this is by appending the annotation to the name of the single-valued navigation property and then setting the value as the Uri to the other record in a PATCH request. Using single-valued navigation propertiesįor existing records on the many side of a one-to-many or many-to-one relationship, you can associate the record by setting a Uri reference to the other record. Both of these tables has a systemuserroles_association collection-valued navigation property. ![]() Many records can be associated with many records.Įach security role (role) may include references to the definition of a systemuser. Multiple contact records can be associated to a single account record using the parentcustomerid_account single-valued navigation property. Many-to-One is the mirror image of a One-to-Many relationship. Many records can be associated with one record. One record can have many records associated with it.Īn account record can have many contact records in the contact_customer_accounts collection-valued navigation property. The following table describes the three types of relationships between tables in Dataverse. For existing Dataverse tables, see the Web API EntityType Reference, for each entity type, see the listed single-valued and collection-valued navigation properties. You can discover which navigation properties exist in the $metadata service document. In OData the relationships are expressed as navigation properties. You can associate individual records in table rows with other records using relationships that exist between the table definitions.
