IDtRecordsetProvider.Fetch

Syntax

Fetch: Array;

Description

The Fetch method imports data according to custom algorithm. The interface must be redefined in the custom 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;

Return ResArray;

End Function Fetch;

End Class MyProvider;

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