ftShortint

ftShortint = 43

Example​

function IsSignedInt8(Field: TField): Boolean;
begin
  Result := Field.DataType = ftShortint;
end;

Usage​

ftShortint identifies a signed 8-bit integer field with range -128 through 127.

Additional Technical Info​

ftShortint is declaration ordinal 43 of TFieldType. It identifies signed 8-bit values -128..127. It differs from unsigned ftByte.

Check range before assignment and preserve Null separately. Database/provider support may expose a wider physical type while the Delphi field enforces this logical domain; do not depend on wraparound.

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