一、创建jack表,并导入一下数据
mysql> create table jack(id char(100),flwo char(100)) engine=myisam;
Query OK, 0 rows affected (0.08 sec)mysql> load data infile '/u01/sqlload/taobao_9_11.txt' into table jack fields terminated by ',';
Query OK, 1469199 rows affected (20.09 sec)
Records: 1469199 Deleted: 0 Skipped: 0 Warnings: 0mysql> select * from jack limit 10;
+-------------+--------+
| id | flwo |
+-------------+--------+
| 13400017749 | 4594 |
| 13400087049 | 5044 |
| 13400826615 | 83029 |
| 13400977755 | 22505 |
| 13401509025 | 2671 |
| 13401584949 | 10435 |
| 13402065168 | 111061 |
| 13402077444 | 2525 |

| 13402156116 | 1935 |
+-------------+--------+
10 rows in set (0.01 sec)
二、将jack表的内容导入到txt文本中
mysql> select * from jack into outfile '/mysql/mysql5.5/load/data.txt' fields terminated by ',';
ERROR 1 (HY000): Can't create/write to file '/mysql/mysql5.5/load/data.txt' (Errcode: 13)
mysql> select * from jack into outfile '/mysql/mysql5.5/load/data.txt' fields terminated by ',';
Query OK, 1469199 rows affected (22.34 sec)mysql> select count(*) from jack;
+----------+
| count(*) |
+----------+
| 1469199 |
+----------+
1 row in set (0.09 sec)
三、修改data.txt的属主
[root@rhel5 load]# chown oracle:oinstall data.txt
[root@rhel5 load]# more data.txt
13400017749,4594
13400087049,5044
13400826615,83029
13400977755,22505
13401509025,2671
四、将data.txt导入到oracle表mysql中
[oracle@rhel5 ~]$ cd /u01/sqlload/
[oracle@rhel5 sqlload]$ cat mysql.ctl
load data
infile '/mysql/mysql5.5/load/data.txt'
append into table mysql
trailing nullcols
( id char terminated by ',',
flow char terminated by whitespace)
[oracle@rhel5 sqlload]$ sqlldr jack/jack control='mysql.ctl' log=input.log direct=trueSQL*Loader: Release 11.2.0.1.0 - Production on 星期一 9月 23 15:15:57 2013Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved.加载完成 - 逻辑记录计数 1469199。
五、验证
SQL> select count(*) from mysql; COUNT(*)
