PL/SQL 快速建立DB_LINK

　　本地数据库SID=T2

　　远程数据库SID=LIFE02

　　假设你的网络设定无误

　　1) vi local database tnsname.ora

life02 =
(description =
(address = (protocol = tcp)(host = 192.168.1.1)(port = 1521))
(connect_data = (sid = life02))
)

　　2)建立属于公开的(public)或者是专属的db link object

SQL> CREATE PUBLIC DATABASE LINK MYTEST
2 CONNECT TO APPLE IDENTIFIED BY APPLE
3 USING 'life02'

Database link created.

　　3)复制远程数据库的table到本地数据库来

SQL> COPY FROM APPLE/APPLE@LIFE02 -
> CREATE ABC -
> USING SELECT * FROM TEST;

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 ABC created.

3 rows selected from APPLE@LIFE02.
3 rows inserted into ABC.
3 rows committed into ABC at DEFAULT HOST connection.

SQL> SELECT * FROM ABC;

ID
----------
100
200
333

SQL>

　　4)从本地端表格复制数据到远程数据库表格上

SQL> COPY FROM JACK/JACK@T2 TO APPLE/APPLE@LIFE02 -
> INSERT TEST -
> USING SELECT * FROM T1;
Array fetch/bind size is 15. (arraysize is 15)
Will commit when done. (copycommit is 0)
Maximum long size is 80. (long is 80)
2 rows selected from JACK@T2.
2 rows inserted into TEST.
2 rows committed into TEST at APPLE@LIFE02.
