IDtRecordsetProvider.Fetch

Syntax

Fetch: Array;

Description

The Fetch method imports data according to user algorithm.

Comments

This method must be redefined in the user class.

Example

Class MyProvider: Object, IDtRecordsetProvider
    Public Function Fetch: Array Of Variant;
    Var
        ResArray: Array[0..1, 0..10] Of Variant;
        i, j: integer;
    Begin
        For j := 0 To 10 Do
            For i := 0 To 1 Do
                If i = 0 Then
                    ResArray[i, j] := "Code-" + j.ToString;
                Else
                    ResArray[i, j] := Math.RandBetween(0, 100);
                End If;
            End For;
        End For;
        Return ResArray;
    End Function Fetch;
End Class MyProvider;

The example is a macro containing implementation of the method that imports data by means of user algorithm. During import, the array that contains two data columns is obtained. There are symbolic values in the first column and random real numbers in the range from 0 to 100 in the second.
