2数据导入 2.1基本语法 $ impdp userid='uname/pwd' directory=pump_dir dumpfile=file01.dmp job_name='' log_file='' remap_schema='scott:sywu' remap_table='tb01:tb02' remap_tablespace='tbs01:ts01' tables='' schemas='' table_exists_action='' tablespaces='' exclude='' sqlfile=''上面有的参数这里就不重复了,因为dump方式导出数据使用了xml格式,所以导入时很容易实现对象重新定义操作,这里主要说几个经常使用的参数:
remap_schema 表示重新定义schema,将旧的schema定义为新的schema,格式old:new,old:new....;
remap_table 表示重新定义表名,格式oldtbname:newtbname,....;
remap_tablespace 表示重新定义表空间名,格式old:new....;
tables 表示要导入的表名,如果未指定则导入dumpfile里的所有表;
schemas 表示要导入的schema对象,如果未指定并且操作用户有权限则导入dumpfile里的所有schema;
table_exists_action 表示当导入表时如果表已经存在时的操作,参数值可以为:append(追加)、replace(替换数据库中存在的)、truncate(删除已经存在的数据,导入dumpfile里面的数据)、skip(不做任何操作);
tablespaces 表示导入的表空间名;
exclude 表示导入排除的对象,DATABASE_EXPORT_OBJECTS表中记录所有的(数据库级别)排除模式,SCHEMA_EXPORT_OBJECTS表中记录schema级别排除对象模式,TABLE_EXPORT_OBJECTS表中记录table级别排除对象模式;
sqlfile 表示不导入数据仅生成导数ddl语句记录在该文件中;
导入数据时要确认导入的用户是否存在,是否有权限访问表空间、是否具有读写directory的权限;
