使用copy命令拷贝数据表

实现同一个数据库不同用户间的表的拷贝

首先看下copy命令的解释

SQL> help copy;

COPY

----

Copies data from a query to a table in the same or another

database. COPY supports CHAR, DATE, LONG, NUMBER and VARCHAR2.

COPY {FROM database | TO database | FROM database TO database}

{APPEND|CREATE|INSERT|REPLACE} destination_table

[(column, column, column, ...)] USING query

where database has the following syntax:

username[/password]@connect_identifier

首先给两个不同的用户授予表空间无限制操作权限

grant ulimited tablespace to test1;

grant ulimited tablespace to test;

SQL> copy from test1/test1@orcl1 to test/test@orcl1 create goods using select * from goods;

Array fetch/bind size is 15. (arraysize is 15)

Will commit when done. (copycommit is 0)

Maximum long size is 80. (long is 80)

Table GOODS created.

16 rows selected from test1@orcl1.

16 rows inserted into GOODS.

16 rows committed into GOODS at test@orcl1.
