ftWord

ftWord = 4

Example​

function IsUnsignedInt16(Field: TField): Boolean;
begin
  Result := Field.DataType = ftWord;
end;

Usage​

ftWord identifies an unsigned 16-bit integer field with range 0 through 65,535.

Additional Technical Info​

ftWord is declaration ordinal 4 of TFieldType. It identifies unsigned 16-bit values 0..65,535.

Do not confuse declaration ordinal 4 or sidebar position 136 with the value domain. Negative assignments and narrowing require explicit validation; signed Smallint cannot represent 32,768..65,535. Null/provider/database constraints remain separate.

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