问题：

使用impdp 导入数据是，出现ORA-14460错误，无法正确导入数据。

Processing object type TABLE_EXPORT/TABLE/TABLE

ORA-39083: Object type TABLE:"SCOTT"."EMP" failed to create with error:

ORA-14460: only one COMPRESS or NOCOMPRESS clause may be specified

Failing sql is:

CREATE TABLE…………

解决方法：

在导入语句中加入：TRANSFORM=segment_attributes:n

加入此参数的意义在于，可与忽略expdp导出时附带的相关表空间和存储子句约束。

注释：

-bash-3.00$ oerr ora 14460

14460, 00000, "only one COMPRESS or NOCOMPRESS clause may be specified"

// *Cause: COMPRESS was specified more than once, NOCOMPRESS was specified more

//     than once, or both COMPRESS and NOCOMPRESS were specified.

// *Action: specify each desired COMPRESS or NOCOMPRESS clause option only once.

-bash-3.00$

新增参数解释：TRANSFORM=segment_attributes:n

• SEGMENT_ATTRIBUTES:[Y | N]

  If the value is specified as Y, then segment attributes (physical attributes, storage attributes, tablespaces, and logging) are included, with appropriate DDL. The default is Y.

  也即在导入表时，原表的相关属性不进行导入。

自己的例子：

impdp gs/gspassword@nbb DIRECTORY=dumpdir DUMPFILE=gs_20171024.dmp logfile=impdp_gs_20171024.log SCHEMAS='gs'

报如下错误：

ORA-39083: Object type TABLE:"GS"."YW_OUT_ORDER" failed to create with error:ORA-14460: only one COMPRESS or NOCOMPRESS clause may be specifiedFailing sql is:CREATE TABLE "GS"."YW_OUT_ORDER" ("ORDER_NUMBER" VARCHAR2(50 BYTE) NOT NULL ENABLE, "MERCHANT_NO" VARCHAR2(20 BYTE), "BB_BANK_ORDER_CODE" VARCHAR2(50 BYTE), "BANK_ORDER_CODE" VARCHAR2(50 BYTE), "MERCHANT_ORDER_CODE" VARCHAR2(50 BYTE), "ID_USER" NUMBER(20,0), "OLD_ORDER_CODE" VARCHAR2(50 BYTE), "MERCHANT_REMARK" VARCHAR2(1000 BYTE), "ORDER_TYPE" CH

数据库导后就没有yw_out_order这张表，通过上面的原因得知，补充导入yw_out_order这张表。

impdp gs/gspassword@nbb DIRECTORY=dumpdir DUMPFILE=gs_20171024.dmp logfile=impdp_gs_20171024_1.log tables=yw_out_order TRANSFORM=segment_attributes:n
