IRdsLink.DeleteConstraint

Syntax

Description

The DeleteConstraint property determines the behavior on attempt to delete elements in the linked dictionary.

Example

Executing the example requires the MDM repository NSI_1 that contains an MDM dictionary with the Dict_1 identifier. The dictionary includes the link with any other MDM dictionary.

Sub UserProc;
Var
    MB: IMetabase;
    MObj: IMetabaseObject;
    Dict: IRdsDictionary;
    Link: IRdsLink;
Begin
    MB := MetabaseClass.Active;
    MObj := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Edit;
    Dict := MObj As IRdsDictionary;
    Link := Dict.Links.Item(0);
    Link.DeleteConstraint := RdsConstraintType.Cascade;
    MObj.Save;
End Sub UserProc;

After executing the example link parameters of the Dict_1 dictionary are changed. While deleting elements in the linked dictionary, elements that have links on the deleted element are also deleted in the current dictionary.
