是否可以从时态表中恢复？
我定义了两个这样的表：

create table lib.x(
  "ID" INTEGER GENERATED ALWAYS AS IDENTITY ( 
       START WITH 1 INCREMENT BY 1 
       NO MINVALUE NO MAXVALUE 
       NO CYCLE NO ORDER 
       CACHE 20 
    ),
    char char(1),
    row_start TIMESTAMP(12) NOT NULL GENERATED ALWAYS AS ROW BEGIN IMPLICITLY hidden,
    row_end TIMESTAMP(12) NOT NULL GENERATED ALWAYS AS ROW END IMPLICITLY hidden,
    row_id TIMESTAMP(12) GENERATED ALWAYS AS TRANSACTION START ID IMPLICITLY hidden,
    PERIOD SYSTEM_TIME(row_start, row_end)
);
create table lib.x_history like lib.x;
alter TABLE lib.x
ADD VERSIONING USE HISTORY TABLE lib.x_history;

然后我做了这个：

insert into lib.x(char) values('a'), ('b'), ('c');
delete from lib.x where id = 2;

是否可以还原id为2的字符“b”？
