现在要从PCA中的sql2005中的数据库common中复制数据到PCB中的oracle 10g中 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
一: |
现在PCB中oracle中创建用户:IMEX |
|
|
|
|
|
|
|
|
|
|
|
|
|
sql> create user IMEX identified by lenovo |
|
|
|
|
|
|
|
|
|
|
|
|
default tablespace users |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
temporary tablespace temp |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
quote unlimited on users |
——给新创建的用户分配磁盘空间,默认是0 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
单独赋予用户权限 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
sql> grant create session to IMEX; |
|
|
|
|
|
|
|
|
|
|
|
|
|
sql> grant create table to IMEX; |
|
|
|
|
|
|
|
|
|
|
|
|
|
sql> grant create sequence to IMEX; |
|
|
|
|
|
|
|
|
|
|
|
|
|
sql> grant create view to IMEX; |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
二: |
在Windows下创建一个ODBC数据源 |
|
|
|
|
|
|
|
|
|
|
|
|
|
控制面板——管理工具——数据源(ODBC),"系统 DSN” 项卡中点击添加按钮,选择相关Oracle驱动 |

这里在"选择源表和视图"的时候,主要要把数据库的目的表名或视图名改成大写的并且去掉前面的用户名, |
|
|
在这一步如果你导入的表中的字段类型是nvarchar的,转换成oracle中对应的类型是 |
|
|
nvarchar2类型,有时候转换的nvarchar2没有长度。所以会报错:缺少左括号 |
|
|
可以点击 图中的Edit 修改类型 |
