IRdsAttribute.Lookup

Syntax

Description

The Lookup property determines an imported attribute with that the Link link is set.

Example

Executing the example requires the MDM repository NSI_1 that contains MDM dictionaries with the Dict_1 and Dict_2 identifiers. The unique GUID identifier must be available in elements for the second dictionary.

Sub UserProc;

Var

MB: IMetabase;

MObj: IMetabaseObject;

Dict, Dict2: IRdsDictionary;

Attrs: IRdsAttributes;

LinkAttr, LookupAttr: IRdsAttribute;

Link: IRdsLink;

Begin

MB := MetabaseClass.Active;

MObj := MB.ItemByIdNamespace("Dict_1", MB.ItemById("NSI_1").Key).Edit;

Dict := MObj As IRdsDictionary;

Dict2 := MB.ItemByIdNamespace("Dict_2", MB.ItemById("NSI_1").Key).Bind As IRdsDictionary;

//Attributes of the first dictionary

Attrs := Dict.Attributes;

//Attribute to link with the dictionary

LinkAttr := Attrs.Add;

LinkAttr.DataType := DbDataType.Integer;

LinkAttr.Id := "LinkAttr";

LinkAttr.Name := Attribute to link;

//Link with the dictionary

Link := Dict.Links.Add;

Link.Attribute := LinkAttr;

Link.Reference := Dict2.Attributes.Key;

Link.Id := "Link";

Link.Name := Link with the dictionary Dict_2;

//Imported attribute GUID

LookupAttr := Attrs.Add;

LookupAttr.Id := "Dict2_GUID";

LookupAttr.Name := "GUID";

LookupAttr.Link := Link;

LookupAttr.Lookup := Dict2.Attributes.GUID;

MObj.Save;

End Sub UserProc;

After executing the example the attribute used to link with the Dict_2 dictionary is created in the first dictionary. The link is established by the Key attribute, then the imported attribute that refers to the GUID attribute of the second dictionary is created in the first dictionary.
