【练习】移动数据----infile *

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

6.查看生成的相关日志：

[oracle@host03 ~]$ ll
total 12
-rw-r--r-- 1 oracle oinstall   23 Nov 11 13:10 base.bad
-rw-r--r-- 1 oracle oinstall  181 Nov 11 13:09 base.ctl
-rw-r--r-- 1 oracle oinstall 1698 Nov 11 13:10 base.log

7.查看bad文件：

[oracle@host03 ~]$ cat base.bad
2,guanyun,guanyunchang

8.查看导入数据：

13:08:39 SCOTT@ORA11GR2>select * from s1_base;

        ID FNAME      LNAME
