1.進(jìn)行plsql后選怎Tools---------》Exports User Ojbects-------------》選中需要導(dǎo)出的table，squence,view,type,function,procedure,trigger。---------------------》

選擇User------------》勾選Include storege或者去掉勾選(include storege表示表空間的意思)-----------》選擇導(dǎo)出文件存放目錄---------》Export按鈕導(dǎo)出

2.下面具體解釋一下Include Storage勾選和不勾選的區(qū)別

(1)不勾選導(dǎo)出的sql如下：

create table TRAVELSKY_XREZAGENT.AUDIT_TRAIL
(
  product       VARCHAR2(32 CHAR) not null,
  environment   VARCHAR2(32 CHAR) not null,
  server        VARCHAR2(32 CHAR) not null,
  resource_path VARCHAR2(256 CHAR) not null,
  action        VARCHAR2(4 CHAR) not null,
  username      VARCHAR2(32 CHAR) not null,
  usergroup     VARCHAR2(32 CHAR) not null,
  address       VARCHAR2(32 CHAR) not null,
  timestamp     DATE default TO_DATE('00-01-01 00:00:00','YY-MM-DD HH24:MI:SS') not null,
  status        VARCHAR2(16 CHAR),
  data          NCLOB
)
;

(2)勾選后導(dǎo)出的sql如下，加上了table所屬的表空間，以及可用的表空間限制

create table TRAVELSKY_XREZAGENT.AUDIT_TRAIL
(
  product       VARCHAR2(32 CHAR) not null,
  environment   VARCHAR2(32 CHAR) not null,
  server        VARCHAR2(32 CHAR) not null,
  resource_path VARCHAR2(256 CHAR) not null,
  action        VARCHAR2(4 CHAR) not null,
  username      VARCHAR2(32 CHAR) not null,
  usergroup     VARCHAR2(32 CHAR) not null,
  address       VARCHAR2(32 CHAR) not null,
  timestamp     DATE default TO_DATE('00-01-01 00:00:00','YY-MM-DD HH24:MI:SS') not null,
  status        VARCHAR2(16 CHAR),
  data          NCLOB
)
tablespace OPENJAW_DATA
  pctfree 10
  initrans 1
  maxtrans 255;

3.下面解釋一下Include User勾選和不勾選的區(qū)別。

(1)不勾選Include User

create table AUDIT_TRAIL
(
  product       VARCHAR2(32 CHAR) not null,
  environment   VARCHAR2(32 CHAR) not null,
  server        VARCHAR2(32 CHAR) not null,
  resource_path VARCHAR2(256 CHAR) not null,
  action        VARCHAR2(4 CHAR) not null,
  username      VARCHAR2(32 CHAR) not null,
  usergroup     VARCHAR2(32 CHAR) not null,
  address       VARCHAR2(32 CHAR) not null,
  timestamp     DATE default TO_DATE('00-01-01 00:00:00','YY-MM-DD HH24:MI:SS') not null,
  status        VARCHAR2(16 CHAR),
  data          NCLOB
)
;

(2)勾選上Include User，會(huì)在create table tablename的tablename前面加上User的名字，如下多了一個(gè)TRAVELSKY_XREZAGENT

create table TRAVELSKY_XREZAGENT.AUDIT_TRAIL
(
  product       VARCHAR2(32 CHAR) not null,
  environment   VARCHAR2(32 CHAR) not null,
  server        VARCHAR2(32 CHAR) not null,
  resource_path VARCHAR2(256 CHAR) not null,
  action        VARCHAR2(4 CHAR) not null,
  username      VARCHAR2(32 CHAR) not null,
  usergroup     VARCHAR2(32 CHAR) not null,
  address       VARCHAR2(32 CHAR) not null,
  timestamp     DATE default TO_DATE('00-01-01 00:00:00','YY-MM-DD HH24:MI:SS') not null,
  status        VARCHAR2(16 CHAR),
  data          NCLOB
)
;
