1.在cmd中輸入 exp username/password@連接串
回車，在進入如下時，輸入no，就ok了
導出表數據(yes/no)：yes> no
2.
進入plsql
找到table那個大項，點出來，下邊會羅列出許多表
右鍵點中你所需要的那個表名
找到DBMS_Metadata
然后選項里有ddl
彈出來那個窗口就是你的表結構，拷貝出來直接在另一個庫里執行就可以啦
-----------------------------補充------------------------
PLSQL里
tools下
export user objects of
按shift批量選擇表
執行就行了

exp/imp工具；
帶參數：rows=y —— 帶數據導出導入；
rows=n —— 不帶數據的導出導入，只移植結構
只導出3張表的結構：
exp user/pasword@dbServerName owner=user tables=(tb1,tb2,tb3) rows=n file=c:\1.dmp
連帶數據導出：
exp user/pasword@dbServerName owner=user tables=(tb1,tb2,tb3) rows=y file=c:\2.dmp
imp user2/pasword@dbServerName2 fromuser=user touser=user2 file=c:\1.dmp
或者
imp user2/pasword@dbServerName2 fromuser=user touser=user2 file=c:\2.dmp

方法一：
exp userid=scott/tiger owner=scott
imp userid=scott/tiger full=y indexfile=scott.sql
……

把前面的REM去了，再去掉最后一行，創建表的DDL就OK了。
方法二：
set pagesize 0
set long 90000
set feedback off
set echo off
spool get_allddl.sql
connect USERNAME/PASSWORD@SID;
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name)
FROM USER_TABLES u;
SELECT DBMS_METADATA.GET_DDL('INDEX',u.index_name)
FROM USER_INDEXES u;
spool off;
My Test:
set pagesize 0
set long 90000
set feedback off
set echo off
spool get_allddl.sql
connect username/password@database;
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name)
FROM USER_TABLES u where table_name = 'USER_INFO';
spool off;
SET HEADING OFF;
SET ECHO OFF;
SET LONG 90000;
SPOOL D:\test.txt
SELECT dbms_metadata.get_ddl('TABLE','USER_INFO') FROM SYS.DBA_USERS WHERE USERNAME = 'GINGKO';
SPOOL OFF;
