Oracle impdp参数说明和导入数据库的SQL语句写法

一、impdp导入数据库的SQL写法

1、按用户导入schemas=SYSTEM,数据库名EFMIS

impdp system/orcl@orcl  **(@orcl 可以不加)  **dumpfile=EFMIS.DMP  directory=tian  schemas=SYSTEM;

2、并行进程PARALLEL

impdp system/orcl@orcl  **(@orcl 可以不加)  **dumpfile=EFMIS.DMP  directory=tian  parallel=40 job\_name=SYSTEM;

3、按表名导入

impdp system/orcl@orcl  **(@orcl 可以不加)  **  tables=name,age dumpfile=EFMIS.DMP  directory=tian;

4、按查询条件导入

impdp system/orcl@orcl  **(@orcl 可以不加)  **tables=name,age dumpfile=EFMIS.DMP  directory=tian;

5、导入整个数据库

impdp system/orcl@orcl  **(@orcl 可以不加)** directory=tian dumpfile=EFMIS.DMP full=y;

6、按表空间导入

impdp system/orcl@orcl  **(@orcl 可以不加)  **tablespaces=name,age dumpfile=EFMIS.DMP  directory=tian;

以上如果想要连log日志一起导入，直接在dumpfile=EFMIS.DMP后加上logfile=EFMIS.LOG即可

如果数据表中表已经存在，会提示错误，在后面加上ignore=y就可以了

例如：impdp system/orcl@orcl  **(@orcl 可以不加)  **dumpfile=EFMIS.DMP  logfile=EFMIS.LOGdirectory=tian full=y;

**程序报错：****expdp ORA-14460: only one COMPRESS or NOCOMPRESS clause may be specified**

**如果程序导入报错可以加入：TRANSFORM=segment\_attributes:n**

**impdp参数表：**
