truncate
trailing nullcols

4.查看执行后当前目录生成的文件：

[oracle@host03 ~]$ ls
base.ctl  base_data.bad  base_data.dat  base.log

5.查看bad文件，还是那条过长的记录没有导入：

[oracle@host03 ~]$ cat base_data.bad
2,guanyu,"guan,yunchang"

6.查看导入记录：

21:40:00 SYS@ORA11GR2>conn scott/tiger
Connected.
21:40:38 SCOTT@ORA11GR2>select * from s1_base;

        ID FNAME      LNAME
