ftLongWord

ftLongWord = 42

Example

function IsUnsignedInt32(Field: TField): Boolean;
begin
  Result := Field.DataType = ftLongWord;
end;

Usage

ftLongWord identifies an unsigned 32-bit integer field with range 0 through 4,294,967,295.

Additional Technical Info

ftLongWord is declaration ordinal 42 of TFieldType. It identifies an unsigned 32-bit domain, 0..4,294,967,295.

Values above signed Integer maximum require a compatible Variant/provider/destination type; casting through signed 32-bit can appear negative. Validate negative inputs and narrowing rather than wrapping. Native Delphi also has a later ftLargeUint that the current script importer omits; ftLongWord is not unsigned 64-bit.

The example only inspects metadata and was source-reviewed; no conversion/dataset/database/runtime/image test ran.
