Oracle expdp参数说明和导出数据库的SQL语句写法

一、expdp导出数据库的SQL写法

1、按用户导出schemas=SYSTEM,数据库名EFMIS

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

2、并行进程PARALLEL

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

3、按表名导出

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

4、按查询条件导出

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

5、导出整个数据库

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

6、按表空间导出

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

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

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