Oracle相关操作示例（导出导入dmp需要采用）

删除用户：drop user pnxd cascade;

导出数据：exp pnxd/padmin@A file=c:b.dmp full=y

导入数据：imp pnxd/padmin@PNXD file=c:b.dmp ignore=y full=y

创建用户：create user pnxd identified by padmin

赋于权限：grant connect,resource to pnxd
授予DBA:grant DBA to pnxd

导入新的数据库需重建权限

创建表空间

CREATE TABLESPACE P2P_NXD
LOGGING
DATAFILE 'D:appStephenproduct11.2.0dbhome_1P2PNXD.DBF'
SIZE 32M
AUTOEXTEND ON
NEXT 32M MAXSIZE 2048M
EXTENT MANAGEMENT LOCAL;

创建序列

create sequence 序列名
minvalue 1maxvalue 99999999start with 1increment by 1
序列名.NEXTVAL 得到一个唯一数

create sequence t_sys_Roles_seq
minvalue 1 maxvalue 999999999 start with 1 increment by 1
