     这里尤其指出的是在   11.2.0.2以上有个新增的参数,SEGMENT_CREATION,如果设置其为n的话,ddl语句就不包含SEGMENT CREATION IMMEDIATE字段。如下:
。。。。
"ISSUE_TYPE" NUMBER(6,0) DEFAULT 0,
"CSTDTN_BANK_ID" NUMBER(6,0)
) SEGMENT CREATION IMMEDIATE
PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255

TRANSFORM

Default: There is no default

Purpose

Enables you to alter object creation DDL for objects being imported.

Syntax and Description

TRANSFORM = transform_name:value[:object_type]

 

The transform_name specifies the name of the transform. The possible options are as follows:

The type of value specified depends on the transform used. Boolean values (y/n) are required for the SEGMENT_ATTRIBUTES, STORAGE, and OID transforms. Integer values are required for the PCTSPACE transform.

The object_type is optional. If supplied, it designates the object type to which the transform will be applied. If no object type is specified, then the transform applies to all valid object types. The valid object types for each transform are shown in Table 3-1.

Example

For the following example, assume that you have exported the employees table in the hr schema. The SQL CREATE TABLE statement that results when you then import the table is similar to the following:

CREATE TABLE "HR"."EMPLOYEES" 
   ( "EMPLOYEE_ID" NUMBER(6,0), 
     "FIRST_NAME" VARCHAR2(20), 
     "LAST_NAME" VARCHAR2(25) CONSTRAINT "EMP_LAST_NAME_NN" NOT NULL ENABLE, 
     "EMAIL" VARCHAR2(25) CONSTRAINT "EMP_EMAIL_NN" NOT NULL ENABLE, 
     "PHONE_NUMBER" VARCHAR2(20), 
     "HIRE_DATE" DATE CONSTRAINT "EMP_HIRE_DATE_NN" NOT NULL ENABLE, 
     "JOB_ID" VARCHAR2(10) CONSTRAINT "EMP_JOB_NN" NOT NULL ENABLE, 
     "SALARY" NUMBER(8,2), 
     "COMMISSION_PCT" NUMBER(2,2), 
     "MANAGER_ID" NUMBER(6,0), 
     "DEPARTMENT_ID" NUMBER(4,0)
   ) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
  STORAGE(INITIAL 10240 NEXT 16384 MINEXTENTS 1 MAXEXTENTS 121
  PCTINCREASE 50 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
  TABLESPACE "SYSTEM" ;

 

If you do not want to retain the STORAGE clause or TABLESPACE clause, then you can remove them from the CREATE STATEMENT by using the Import TRANSFORMparameter. Specify the value of SEGMENT_ATTRIBUTES as n. This results in the exclusion of segment attributes (both storage and tablespace) from the table.

> impdp hr TABLES=hr.employees DIRECTORY=dpump_dir1 DUMPFILE=hr_emp.dmp
  TRANSFORM=SEGMENT_ATTRIBUTES:n:table

 

The resulting CREATE TABLE statement for the employees table would then look similar to the following. It does not contain a STORAGE or TABLESPACE clause; the attributes for the default tablespace for the HR schema will be used instead.

CREATE TABLE "HR"."EMPLOYEES" 
   ( "EMPLOYEE_ID" NUMBER(6,0), 
     "FIRST_NAME" VARCHAR2(20), 
     "LAST_NAME" VARCHAR2(25) CONSTRAINT "EMP_LAST_NAME_NN" NOT NULL ENABLE, 
     "EMAIL" VARCHAR2(25) CONSTRAINT "EMP_EMAIL_NN" NOT NULL ENABLE, 
     "PHONE_NUMBER" VARCHAR2(20), 
     "HIRE_DATE" DATE CONSTRAINT "EMP_HIRE_DATE_NN" NOT NULL ENABLE, 
     "JOB_ID" VARCHAR2(10) CONSTRAINT "EMP_JOB_NN" NOT NULL ENABLE, 
     "SALARY" NUMBER(8,2), 
     "COMMISSION_PCT" NUMBER(2,2), 
     "MANAGER_ID" NUMBER(6,0), 
     "DEPARTMENT_ID" NUMBER(4,0)
   );

 

As shown in the previous example, the SEGMENT_ATTRIBUTES transform applies to both storage and tablespace attributes. To omit only the STORAGE clause and retain the TABLESPACE clause, you can use the STORAGE transform, as follows:

> impdp hr TABLES=hr.employees DIRECTORY=dpump_dir1 DUMPFILE=hr_emp.dmp
  TRANSFORM=STORAGE:n:table

 

The SEGMENT_ATTRIBUTES and STORAGE transforms can be applied to all applicable table and index objects by not specifying the object type on the TRANSFORMparameter, as shown in the following command:

> impdp hr DIRECTORY=dpump_dir1 DUMPFILE=hr.dmp SCHEMAS=hr TRANSFORM=SEGMENT_ATTRIBUTES:n
