The delete action to be performed.

TipwodataSchemaAssociationOnDeletes = (
  daNone, 
  daCascade, 
  daSetNull, 
  daSetDefault
);

Default Value

daNone

Remarks

The delete action to be performed.

Possible values are:


0 (daNone)	Only the specified entry instance within SchemaAssociationFromRoleEntity is deleted. This is the default value.
1 (daCascade)	After the specified entry instance is deleted within SchemaAssociationFromRoleEntity, the action is applied to the entry instance within the SchemaAssociationToRoleEntity. For example, a single Customer is associated with multiple Orders. When a Customer is deleted, all Orders associated with the Customer will be deleted.
2 (daSetNull)	All properties of related entities that are tied to properties of the source entity via a referential constraint and that do not participate in other referential constraints will be set to null. This value is only applicable to OData Version 4.
3 (daSetDefault)	All properties of related entities that are tied to properties of the source entity via a referential constraint and that do not participate in other referential constraints will be set to their default value. This value is only applicable to OData Version 4.

The size of the array is controlled by the SchemaAssociationCount property.

This property is read-only and not available at design time.
