一：用命令 imp/exp 的方式进行数据的导入和导出
一：文件后缀名：
二：oracle 导出 exp 命令
1 echo 开始备份数据库 2 if not exist D:oracle_bakfiles md D:oracle_bakfiles 3 if not exist D:oracle_baklogs md D:oracle_baklogs 4 5 set var=%date:~0,4%%date:~5,2%%date:~8,2%%time:~9,2% 6 exp GDSDCZJ/GDSDCZJ1234@192.168.1.100/pdborcl file=D:oracle_bakfilesGDSDCZJ_%var%.dmp log=D:oracle_baklogsGDSDCZJ_%var%.log 7 echo 备份数据库结束 8 9 echo 删除30天前的备份记录 10 forfiles /p "D:oracle_bak" /s /m *.dmp /d -30 /c "cmd /c del @path" 11 forfiles /p "D:oracle_bak" /s /m *.log /d -30 /c "cmd /c del @path" 12 echo 删除30天前的备份记录结束 13 exit 14
三：oracle 导入 imp 命令
1 echo 开始导入数据库 2 set var=%date:~0,4%%date:~5,2%%date:~8,2% 3 imp GDSDYTH/GDSDYTH@192.168.0.110/pdborcl full=y ignore=y file=D:oracle_bakfilesgdsd_czj_%var%.dmp log=D:oracle_baklogsgdsd_czj_to_apa_imp_%var%.log 4 echo 导入数据库结束 5 exit 6
四：oracle 删除用户 再创建用户并赋予相对应的操作权限，然后再 导入 imp 命令
1 drop user sync_plus_1_0501 cascade; 2 create user sync_plus_1_0501 identified by sync_plus_1_0501 3 default tablespace sync_plus_1 temporary tablespace temp quota 500m on users; 4 grant all privileges to sync_plus_1_0501 ; 5 grant ALLTAX to SYNC_PLUS_1_0501; 6 grant ALLINONE_JX to sync_plus_1_0501 ; 7 grant ALLOUTSIDE to sync_plus_1_0501 ; 8 grant dba to sync_plus_1_0501; 9 grant RDCX to sync_plus_1_0501; 10 quit; 11
1 echo 开始导入数据库 2 sqlplus sys/oracle@192.168.1.168/pdborcl as sysdba @F:decoumentDB_softcreateUser.sql 3 4 set var=%date:~0,4%%date:~5,2%%date:~8,2% 5 imp sync_plus_1_0501/sync_plus_1_0501@192.168.1.168/pdborcl full=y ignore=y 6 file=F:decoumentDB_softimp_dataSYNC_PLUS_1_%var%.dmp 7 log=F:decoumentDB_softimp_datalogsSYNC_PLUS_1_to_apa_imp_%var%.log 8 echo 导入数据库结束 9 exit；
执行 效果：
五：每天自动创建当天日期为后缀名的oracle用户。并给该用户导入数据
1：看执行效果
2：上脚本：
Imp_toDay_Data.bat
1 echo 开始导入数据库 2 set var=%date:~0,4%%date:~5,2%%date:~8,2% 3 sqlplus sys/oracle@192.168.1.168/pdborcl as sysdba @F:decoumentDB_softimp_toDay_DatacreateUser.sql 4 5 imp sync_plus_1_%var%/sync_plus_1_%var%@192.168.1.168/pdborcl full=y ignore=y file=F:decoumentDB_softSYNC_PLUS_1_%var%.dmp log=F:decoumentDB_softimp_toDay_DatalogsSYNC_PLUS_1_to_apa_imp_%var%.log 6 echo 导入数据库结束 7createUser.sql
1 declare 2 v_time varchar(20); 3 v_sql varchar(4000); 4 v_count int :=0; 5 v_count_sql varchar(4000); 6 v_username varchar(300); 7 begin 8 select to_char(sysdate,'yyyyMMdd') into v_time from dual; 9 v_username :='SYNC_PLUS_1_'||v_time; 10 dbms_output.put_line(v_username); 11 SELECT count(USERNAME) into v_count FROM ALL_USERS t where t.username =v_username ; 12 dbms_output.put_line(v_count); 13 if v_count = 0 then 14 v_sql :='create user sync_plus_1_'||v_time ||' identified by sync_plus_1_'||v_time ||' default tablespace sync_plus_1 temporary tablespace temp quota 500m on users'; 15 dbms_output.put_line(v_sql); 16 execute immediate v_sql; 17 end if; 18 v_sql:='grant all privileges to sync_plus_1_'||v_time ; 19 dbms_output.put_line(v_sql); 20 execute immediate v_sql; 21 v_sql:='grant ALLTAX to sync_plus_1_'||v_time; 22 dbms_output.put_line(v_sql); 23 execute immediate v_sql; 24 v_sql:='grant ALLINONE_JX to sync_plus_1_'||v_time ; 25 dbms_output.put_line(v_sql); 26 execute immediate v_sql; 27 v_sql:='grant ALLOUTSIDE to sync_plus_1_'||v_time ; 28 dbms_output.put_line(v_sql); 29 execute immediate v_sql; 30 v_sql:='grant dba to sync_plus_1_'||v_time; 31 dbms_output.put_line(v_sql); 32 execute immediate v_sql; 33 v_sql:='grant RDCX to sync_plus_1_'||v_time; 34 dbms_output.put_line(v_sql); 35 execute immediate v_sql; 36 commit; 37 end; 38 / 39 40 quit;
六： 对oracle数据库某个用户 进行删表后再导入数据
Imp_SYNC_PLUS_1.bat
1 echo 开始导入数据库 2 sqlplus /nolog @F:decoumentDB_softimp_datacreateUser.sql 3 4 set var=%date:~0,4%%date:~5,2%%date:~8,2% 5 imp SYNC_PLUS_1/SYNC_PLUS_1@192.168.1.168/pdborcl full=y ignore=y file=F:decoumentDB_softSYNC_PLUS_1_%var%.dmp log=F:decoumentDB_softimp_datalogsSYNC_PLUS_1_to_apa_imp_%var%.log 6 echo 导入数据库结束 7 exit;
createUser.sql

二：使用 PL/SQL 工具 进行数据的导入 导出
1： 前提：需要安装oracle Xe 的客户端
2： 使用Plsql 工具 进行demp 文件 的数据导入
