用sqlldr从mysql导出一个表的数据到oracle

用sqlldr从mysql导出一个表的数据到oracle 用sqlldr从mysql导出一个表的数据到oracle

代码:--------------------------------------------------------------------------------

1 进入mysql

mysql> select UUID, CYC_CODE, b03_05, b03_06, b03_07, b03_08, b03_09, b03_10, b03_11, b03_12, Cate_Item_Code, product_name, product_unit

from jb603_jb603_sub3 into outfile 'd:/tmp/603sub.txt';

Query OK, 79537 rows affected (0.48 sec)

mysql> show create table jb603_jb603_sub3;

| jb603_jb603_sub3 | CREATE TABLE `jb603_jb603_sub3` (

`UUID` varchar(32) NOT NULL default '',

`CYC_CODE` char(2) NOT NULL default '',

`b03_05` decimal(11,2) default '0.00',

`b03_06` decimal(11,2) default '0.00',

`b03_07` decimal(11,2) default '0.00',

`b03_08` decimal(11,2) default '0.00',

`b03_09` decimal(9,0) default '0',

`b03_10` decimal(11,2) default '0.00',

`b03_11` decimal(11,2) default '0.00',

`b03_12` decimal(11,2) default '0.00',

`Cate_Item_Code` varchar(7) NOT NULL default '',

`product_name` varchar(60) default '',

`product_unit` varchar(20) default '',

PRIMARY KEY (`UUID`,`CYC_CODE`,`Cate_Item_Code`)

) TYPE=InnoDB |

将语句整理成oracle支持的格式：

CREATE TABLE jb603_jb603_sub3 (

UUID varchar(32) NOT NULL ,

CYC_CODE char(2) NOT NULL ,

b03_05 number(11,2) ,

b03_06 number(11,2) ,

b03_07 number(11,2) ,

b03_08 number(11,2) ,

b03_09 number(9,0) ,

b03_10 number(11,2) ,

b03_11 number(11,2) ,

b03_12 number(11,2) ,

Cate_Item_Code varchar(7) NOT NULL ,

product_name varchar(60) ,

product_unit varchar(20) ,

PRIMARY KEY (UUID,CYC_CODE,Cate_Item_Code));

2 编写sqlldr控制文件t.ctl

load data

infile 'd:/tmp/603sub.txt'

into table jb603_jb603_sub3

replace

fields terminated by x'09'

(UUID, CYC_CODE, b03_05, b03_06, b03_07, b03_08, b03_09, b03_10, b03_11, b03_12, Cate_Item_Code, product_name, product_unit)

3运行sqlplus /nolog

SQL> conn lt/lt5@ibmlt

建立jb603_jb603_sub3表

SQL> CREATE TABLE jb603_jb603_sub3 (

2 UUID varchar(32) NOT NULL ,

3 CYC_CODE char(2) NOT NULL ,

4 b03_05 number(11,2) ,

5 b03_06 number(11,2) ,

6 b03_07 number(11,2) ,

7 b03_08 number(11,2) ,

8 b03_09 number(9,0) ,

9 b03_10 number(11,2) ,

10 b03_11 number(11,2) ,

11 b03_12 number(11,2) ,

12 Cate_Item_Code varchar(7) NOT NULL ,

13 product_name varchar(60) ,

14 product_unit varchar(20) ,

15 PRIMARY KEY (UUID,CYC_CODE,Cate_Item_Code));

表已创建。

4 ho进入操作系统命令行

在操作系统命令行运行sqlldr lt/lt_5@ibmlt d:/tmp/t.ctl

....

达到提交点，逻辑记录计数79537

5 exit回到sqlplus

SQL> select count(*)from JB603_JB603_SUB3;

COUNT(*)

----------

79537

6另外，我不明白为什么用外部表方式不能成功

sqlldr lt/lt5@ibmlt d:/tmp/t.ctl external_table=generate_only

产生t.log
