oracle 导出的insert语句过长 运行插入错误的解决

因客户给的数据过长，insert语句执行报错

所以在测试环境下 写程序导入

但是要部署到linux下 sql文件执行报错 最终找到oracle备份和恢复解决办法

方法如下

//用system用户连接数据库
sqlplus system/admin@orcl as sysdba

//赋权给root用户

 grant CREATE ANY DIRECTORY to root;

grant exp_full_database to root;

//用root用户连接数据库
sqlplus root/root@orcl as sysdba
//环境变量设置
create or replace directory 变量名称 as '路径'
create or replace directory dir_dp as 'D:/oracle/dir_dp'
//备份脚本
expdp system/admin@orcl directory=dir_dp dumpfile=root.dat logfile=root.log schemas=root
//删除root用户
sqlplus system/admin@orcl 
drop user root cascade; 
//重新创建root用户
sqlplus system/admin@orcl
//或者引用:oracle建表建用户.txt
create user ARAdmin identified by AR#Admin# default tablespace ARSYSTEM temporary tablespace ARTMPSPC quota unlimited on arsystem;
grant alter session,create cluster,create database link,create sequence,create 
session,create synonym,create table,create 
view,create procedure,create trigger,query rewrite to ARAdmin;
//数据库导入(如果是单张表，先删除表，再导入 drop table 表名)
impdp system/admin@orcl directory=dir_dp dumpfile=ARADMIN.DAT logfile=ARADMIN.log schemas=root remap_tablespace=JEESITE:EESITE_TBSPACE

//表空间不一致（ora-39083）
remap_tablespace=tablespace1:tablespace2

remap_tablespace=JEESITE:EESITE_TBSPACE

//oracle建表建用户.txt

--表空间  
CREATE TABLESPACE JEESITE  
DATAFILE 'E:/app/Administrator/oradata/orcl/JEESITE_TBSPACE.dbf' size 800M  
         EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;   
--索引表空间  
CREATE TABLESPACE JEESITE_INDEX  
DATAFILE 'E:/app/Administrator/oradata/orcl/JEESITE_TBSPACE_INDEX.dbf' size 512M           
         EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;       
  
--2.建用户  
create user root identified by root   
default tablespace JEESITE;  
   
--3.赋权  
grant connect,resource to root;  
grant create any sequence to root;  
grant create any table to root;  
grant delete any table to root;  
grant insert any table to root;  
grant select any table to root;  
grant unlimited tablespace to root;  
grant execute any procedure to root;  
grant update any table to root;  
grant create any view to root;
