1.创建表空间不论是Lnux环境,还是Wndows环境,都要首先创建好表空间的存放路径,如:/opt/oracle/oradata/cocis 或 D:\oracle\o
Oracle Version:Oracle10.2.0.1
Author: Cocis
当在数据库中创建用户时,基于应用性能和管理方面的考虑,最好为不同的用户创建独立的表空间。
1.创建表空间
不论是Lnux环境,还是Wndows环境,都要首先创建好表空间的存放路径,如:
/opt/oracle/oradata/cocis 或 D:\oracle\oradata\cocis
若事先不创建该目录路径,则在创建表空间的时候会出错。
然后执行如下命令:
SQL> create tablespace cocis
2 datafile 'D:\oracle\oradata\cocis\cocis01.dbf'
3 size 100M AutoExtend On Next 10M Maxsize 2048M
4 extent management local
5 segment space management auto
6 /
表空间已创建。
2.为应用创建用户
创建用户的同时,为用户指定缺省的永久表空间和临时表空间。
SQL> create user cocis identified by cocis
2 default tablespace cocis
3 temporary tablespace temp;
用户已创建。
SQL> select username,default_tablespace,temporary_tablespace
2 from dba_users
3 where username='COCIS';
USERNAME DEFAULT_TABLESPACE TEMPORARY_TABLESPACE
------------------------------ ------------------------------ ------------------
COCIS COCIS TEMP
SQL> select username,user_id,password,default_tablespace,temporary_tablespace
2 from dba_users
3 where username='COCIS';
USERNAME USER_ID PASSWORD TEMPORARY_TABLESPACE
------------------------------ ---------- ------------------------------ -----------------------
COCIS 61 E031F623C0F15D34 COCIS
3.权限的授予
SQL> grant connect,resource to cocis;
授权成功。
注释:当用户创建之后,一般只需要授予CONNECT和RESOURCE这两个角色即可。若要单独进行授权,则需执行单独的授权命令,,如grant create table to cocis;等。
SQL> revoke unlimited tablespace from cocis;
撤销成功。
SQL> alter user cocis quota unlimited on cocis;
用户已更改。
注释:为了更严谨的管理,可以回收用户的UNLIMITED TABLESPACE权限,然后对用户的空间限额进行单独授权。

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.

MySQL is not a programming language, but its query language SQL has the characteristics of a programming language: 1. SQL supports conditional judgment, loops and variable operations; 2. Through stored procedures, triggers and functions, users can perform complex logical operations in the database.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is an open source relational database management system suitable for data storage, management, query and security. 1. It supports a variety of operating systems and is widely used in Web applications and other fields. 2. Through the client-server architecture and different storage engines, MySQL processes data efficiently. 3. Basic usage includes creating databases and tables, inserting, querying and updating data. 4. Advanced usage involves complex queries and stored procedures. 5. Common errors can be debugged through the EXPLAIN statement. 6. Performance optimization includes the rational use of indexes and optimized query statements.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

InnoDB's lock mechanisms include shared locks, exclusive locks, intention locks, record locks, gap locks and next key locks. 1. Shared lock allows transactions to read data without preventing other transactions from reading. 2. Exclusive lock prevents other transactions from reading and modifying data. 3. Intention lock optimizes lock efficiency. 4. Record lock lock index record. 5. Gap lock locks index recording gap. 6. The next key lock is a combination of record lock and gap lock to ensure data consistency.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
