　　创建文件lottu.txt；和表tbl_load_01。

[oracle@oracle235 ~]$ seq 1000|awk -vOFS="," '{print $1,"lottu",systime()-$1}' > lottu.txt
[oracle@oracle235 ~]$ sqlplus lottu/li0924

SQL> create table tbl_load_01 (id number,name varchar2(10),accountid number);
Table created.

3.2 创建控制文件lottu.ctl

load data

    infile '/home/oracle/lottu.txt'
    truncate into table tbl_load_01
    fields terminated by ','
    trailing nullcols

(
 id ,
 name,
 accountid
)

四.Oracle卸载数据-sqludr

　　sqludr是将Oracle数据表导出到文本中；是牛人楼方鑫开发的。并非Oracle自带工具；需要下载安装才能使用。

4.1 sqludr安装

[oracle@oracle235 ~]$ unzip sqluldr2linux64.zip 
Archive: sqluldr2linux64.zip
 inflating: sqluldr2linux64.bin   
[oracle@oracle235 ~]$ mv sqluldr2linux64.bin $ORACLE_HOME/bin/sqludr

4.2 查看sqludr帮助

[oracle@oracle235 ~]$ sqludr -?

4.3 执行sqludr

[oracle@oracle235 ~]$ sqludr lottu/li0924 query="tbl_load_01" file=lottu01.txt field=","
      0 rows exported at 2018-08-13 23:47:55, size 0 MB.
    1000 rows exported at 2018-08-13 23:47:55, size 0 MB.
