要求：
①指定bad文件；
②挂在之前将目标表delete；
③导入的的数据在控制文件中。
1.创建目录对象：
13:05:24 SYS@ORA11GR2>create or replace directory dir_dt as '/home/oracle';
Directory created.
2.将读写权限给scott用户：
13:05:28 SYS@ORA11GR2>grant read,write on directory dir_dt to scott;
Grant succeeded.
3.scott用户下创建测试表：
13:07:17 SYS@ORA11GR2>conn scott/tiger
Connected.
13:07:57 SCOTT@ORA11GR2>create table s1_base(id number(5),fname varchar2(10),lname varchar2(10));
Table created.
4.创建控制文件：
[oracle@host03 ~]$ vi base.ctl
load data
infile *
badfile 'base.bad'
into table s1_base
replace
fields terminated by ','
(id,fname,lname)
begindata
1,zhangfei,zhangyunde
2,guanyun,guanyunchang
3,liubei,liuxuande
5.通过sqlldr将控制文件的数据导入scott用户下的测试表
[oracle@host03 ~]$ sqlldr scott/tiger control=base.ctl
