There is nothing special in the query in that cursor:

CursorValues.SQL.Add('select ID, VALUE from MY_TABLE where (ID = :ID);');
CursorValues.ParamByName('ID').AsInteger := myIDParam; <- here the error occurs

The cursor is not prepared.

Just tried to call Cursor.Prepare prior to Cursor.ParamByName and the error occurs in Cursor.Prepare then.
