PLSQL Developer导入导出数据库

导出步骤:

1 tools ->export user object 选择选项,导出.sql文件

2 tools ->export tables-> Oracle Export 选择选项导出.dmp文件

导入步骤:

1 tools->import tables->SQL Inserts 导入.sql文件

2 tools->import talbes->Oracle Import然后再导入dmp文件

数据库的导入导出成功

 

Tools->Export User Objects导出的是建表语句(包括存储结构)

Tools->Export Tables里面包含三种导出方式:

三种方式都能导出表结构以及数据,网上说三种方法有区别,如下:

Oracle Export,Sql Insert,pl/sql developer
第一种是导出为.dmp的文件格式,.dmp文件是二进制的,可以跨平台,还能包含权限,效率也很不错,用得最广
第二种是导出为.sql文件的,可用文本编辑器查看,通用性比较好,但效率不如第一种,适合小数据量导入导出。尤其注意的是表中不能有大字段(blob,clob,long),如果有,会提示不能导出(提示如下:
table contains one or more LONG columns cannot export in sql format,user Pl/sql developer format instead),可以用第一种和第三种方式导出。
第三种是导出为.pde格式的,.pde为Pl/sql developer自有的文件格式,只能用Pl/sql developer自己导入导出;不能用编辑器查看。

操作选项
一般一些选项选择看字面意思就可以了,重要的上面已经写了(主要include privilege只是包含一些建表信息,并不包括存储过程信息,话说我被这个选项骗了……还是忽略它吧……)

选择drop tables信息中会包含删表语句(注意:选了drop tables就已经默认选了create tables 和 truncate tables),create tables是建表信息,truncate tables和delete tables都是再再插入数据前先删除原有的信息,这两个是二选一,但是truncate tables效率高很多。

where clause可以输入很多命令,比如rownum

 

导出数据到excel文件:
  选中数据表--query data--选中要导出的数据--右键copy to excel
  excel数据导入到
数据库
  1.在Excel中准备好要导入的数据。具体操作:在Excel中,把第一列设置为空列,第二列以后的列应与要导入的数据表的字段相对应。
  2.登录PLSQL Developer,找到需要导入数据的数据库表后,点击右键--edit data,进入了编辑此表的数据对话框,并点击最左侧选中一空行。
  3.copy Excel表中的数据记录,将数据粘贴到上步中PLSQL Developer显示的表列中。
  4.点击PLSQL Developer中的对号按钮进行Post。
