備註

Message Availability

不論呼叫端是連線至伺服器還是離線狀態,此訊息都會正常運作。

Usage

Pass an instance of this class to the Execute method, which returns an instance of DisassociateResponse.

Privileges and Access Rights

若要執行此動作,呼叫端必須擁有 privileges on the entity specified in the entityName parameter and access rights on the records specified in the entityId and relatedEntities parameters. For a list of the privileges required, see Disassociate Privileges.

Notes for Callers

This method removes multiple associations in one transaction between the record specified by the entityId parameter and each record in the relatedEntities parameter for the relationship specified in the relationship parameter.

For a one-to-many relationship, this method clears the ReferencingAttribute in the related record to the value of entityId.

For a many-to-many relationship, this method deletes a record in the intersect table for the relationship. The intersect table name is defined in the IntersectEntityName property for the relationship. You need this when you query for the records. However, you need the relationship name to set the Relationship property. This name is defined in the SchemaName property for the relationship.

Supported Entities

You can use this method to disassociate any records that participate in a relationship, including records for custom entities. You can find the default relationships listed in the Entity Metadata topic for each entity.
