Oracle12C使用記錄

 

  1.

安裝時oracle12C去除勾選爲創建爲容器數據庫

  2.cmd命令

<1>.sqlplus/nolog     // --運行sqlplus命令，進入sqlplus環境，nolog參數表示不登錄；

<2>.conn/as sysdba   //   --以系統管理員(sysdba)的身份連接數據庫；　　　　　　　　  

3.創建表空間

CREATE   TABLESPACE tbs_rap_data

DATAFILE 'E:\Oracle12Cguanwang\table\rap97new2_space.dbf' size 500m

AUTOEXTEND ON

NEXT 200M MAXSIZE 20480M

EXTENT MANAGEMENT LOCAL;

 

4.執行公司oracle語句

create user rap97new2 identified by rap97new2 default tablespace tbs_rap_data temporary tablespace temp profile default;

-- Grant/Revoke role privileges

grant connect to rap97new2;

grant resource to rap97new2;

-- Grant/Revoke system privileges

grant alter session to rap97new2;

grant create any context to rap97new2;

grant create database link to rap97new2;

grant create job to rap97new2;

grant create materialized view to rap97new2;

grant create sequence to rap97new2;

grant create session to rap97new2;

grant create synonym to rap97new2;

grant create table to rap97new2;

grant create trigger to rap97new2;

grant create view to rap97new2;

grant debug connect session to rap97new2;

grant manage scheduler to rap97new2;

    grant unlimited tablespace to rap97new2;

 

 

1. 在PLsql中配置

<1> E:\app\instantclient_12_2

<2> E:\app\instantclient_12_2\oci.dll

oracle環境變量配置：

環境變量： oracle根目錄   E:\app\root\product\12.2.0\dbhome_1\network\admin

NLS_LANG：SIMPLIFIED CHINESE_CHINA.ZHS16GBK

配置 plsql developer 首選項；

 

 

 

1. 導入公司的Oracle數據庫文件

工具——導入表——下側導入文件

 

 

1. 刪除表空間DROP TABLESPACE tbs_rap_data INCLUDING CONTENTS AND DATAFILES;
2. 刪除用戶DROP USER rap97new2 CASCADE；

 

 

一、sys用戶和system用戶
Oracle安裝會自動的生成sys用戶和system用戶
(1)、sys用戶是超級用戶，具有最高權限，具有sysdba角色，有create database的權限，該用戶默認的密碼是change_on_install
(2)、system用戶是管理操作員，權限也很大。具有sysoper角色，沒有create database的權限，默認的密碼是manager
(3)、一般講，對數據庫維護，使用system用戶登錄就可以拉
注意：也就是說sys和system這兩個用戶最大的區別是在於有沒有create database的權限。

（4）scott的默認密碼是tiger

                     Oracle 表及表空間

一個數據庫可以有多個表空間，一個表空間裏可以有多個表。表空間就是存多個表的物理空間；

可以指定表空間的大小位置等。

創建表空間：create tablespace ts1 datafile 'E:\tablespace\ts1.dbf' size 50M;

自動擴展大小：create tablespace ts2 datafile 'E:\tablespace\ts2.dbf' size 50M autoextend on next 10M;

設置最大空間：create tablespace ts3 datafile 'E;:\tablespace\ts3.dbf' size 50M autoextend on next 10M maxsize 1024M;

更改用戶默認表空間：alter database default tablespace ts1;

表空間改名：alter tablespace ts1 rename to tss1;

刪除表空間：drop tablespace ts2 including contents and datafiles;

 

 

 

創建表

Oracle12c添加scott用戶

1.前言

在Oracle12c中，已經沒有了scott這一實例用戶。Oracle學習者們可以通過新建hr用戶或是新建scott用戶，來完成對Oracle的學習。

2.具體流程

• 登錄系統用戶 
  conn / as sysdba;
• 刪除已有的用戶(可選) 
  DROP USER scott cascade;
• 新建用戶，授予權限，連接

CREATE USER scott identified by TIGER ;            

GRANT CREATE SEQUENCE to scott ;

GRANT UNLIMITED TABLESPACE to scott ;

GRANT CREATE SESSION to scott ;

GRANT CREATE SYNONYM to scott ;

GRANT ALTER SESSION to scott;

GRANT CREATE DATABASE LINK to scott;

GRANT CREATE VIEW to scott;

GRANT CREATE TABLE to scott;

ALTER USER scott DEFAULT TABLESPACE USERS;

ALTER USER scott TEMPORARY TABLESPACE TEMP;

CONNECT scott/TIGER

• 新建表格並添加數據

-- DEPT表格

CREATE TABLE DEPT

       (DEPTNO NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY,

    DNAME VARCHAR2(14) ,

    LOC VARCHAR2(13) ) ;

-- EMP表格

CREATE TABLE EMP

       (EMPNO NUMBER(4) CONSTRAINT PK_EMP PRIMARY KEY,

-- BONUS表格

至此，新建scott用戶完成，可以開始學習Oracle了。
