IMetaDictionaryLookup.Where

Syntax

Where: IOrmConditions;

Description

The Where property returns search condition.

Example

Executing the example requires that the repository contains a time series database with the OBJ_FC identifier. The database must have a time series attribute with the COUNTRY identifier.

Sub Main;

Var

MB: IMetabase;

RubDesc: IMetabaseObjectDescriptor;

RubrIn: IRubricatorInstance;

DictInst: IMetaDictionaryInstance;

MetaDLookup: IMetaDictionaryLookup;

Conditions: IOrmConditions;

Cond: IOrmCondition;

i: Integer;

Res: Array Of Integer;

Begin

MB := MetabaseClass.Active;

RubDesc := MB.ItemById("OBJ_FC");

RubrIn := RubDesc.Open(Null) As IRubricatorInstance;

DictInst := RubrIn.Facts;

MetaDLookup := DictInst.CreateLookup("");

Conditions := MetaDLookup.Where;

Cond := Conditions.Add;

Cond.AttributeName := "COUNTRY";

Cond.Value := 512;

i := MetaDLookup.LookupKeys("FACTOR").Length;

Res := New Integer[i];

Res := MetaDLookup.LookupKeys("FACTOR");

For i := 0 To Res.Length - 1 Do

Debug.WriteLine(Res[i].ToString);

End For;

End Sub Main;

After executing the example time series keys that meet the following conditions are displayed in the console window: value of the COUNTRIES attribute equals to 512 in a factor.
