IRdsNonUniqueKeys.FindById

Syntax

FindById(Id: String): IRdsNonUniqueKey;

Parameters

Id. Identifier of the non-unique key, by which the search is executed.

Description

The FindById method searches a non-unique key by identifier in the MDM dictionary.

Comments

Use the IRdsNonUniqueKeys.Remove method to remove a non-unique key by index.

Example

Executing the example requires the MDM repository with the NSI_1 identifier that contains an MDM dictionary with the DICT_1 identifier. The dictionary must have custom attributes with non-unique keys. The first non-unique key is characterized by the Index_1 index, the second non-unique key is characterized by the 1 key.

Add links to the Metabase, Rds system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    MObj: IMetabaseObject;
    Dict: IRdsDictionary;
    Attrs: IRdsAttributes;
    Keys: IRdsNonUniqueKeys;
Begin
    MB:= MetabaseClass.Active;
    MObj := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Edit;
    Dict := MObj As IRdsDictionary;
    Attrs := Dict.Attributes;
    Keys := Dict.NonUniqueKeys;
    Keys.FindById("Index_1");
    Keys.FindByKey(1);
    Keys.Remove(0);
    Keys.RemoveByKey(1);
    MObj.Save;
End Sub UserProc;

After executing the example non-unique keys are found and then removed by specified indexes and keys.
