2:下面具体解释一下Include Storage勾选和不勾选的区别

1)不勾选导出的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)勾选后导出的sql如下,加上了table所属的表空间,以及可用的表空间限制

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:下面解释一下Include User勾选和不勾选的区别。

1)不勾选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)勾选上Include User,会在create table tablename的tablename前面加上User的名字,如下多了一个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
)
;
