一.实验步骤

#创建表
create table fuwa.deptno(id int,name varchar(100),addr varchar(200));
#创建索引
create index fuwa.idx_deptno on fuwa.deptno (id);
#批量插入数据
declare
 sqlstr varchar;
begin
 for i in 1..10000 loop
  sqlstr:='insert into  fuwa.deptno values ';
   for j in 1..100 loop
     sqlstr=sqlstr || '(' ||j|| ',''test'',''testestewt''),';
   end loop;
   sqlstr=rtrim(sqlstr,',') ;
   execute immediate sqlstr;
  end loop;
  commit;
end;
select count(*) from fuwa.deptno;

#备份表
backup table fuwa.deptno backupset '/dmdb8/dmdata/fuwa/bak/tab_fuwa_deptno_bak';
#模拟删除表fuwa.deptno
drop table fuwa.deptno ;
#执行表结构还原。表备份和表中都包含索引，如果直接执行表数据还原会报错：还原表中存在二级索引或冗余约束。
restore table fuwa.deptno struct from backupset '/dmdb8/dmdata/fuwa/bak/tab_fuwa_deptno_bak';
#执行表数据还原
restore table fuwa.deptno from backupset '/dmdb8/dmdata/fuwa/bak/tab_fuwa_deptno_bak';
