MYSQL完全入门(Windows版)_MySQL

一、MySQL简介
MySQL是一个小巧灵珑的数据库服务器软件,对于中、小型应用系统是非常理想的。除了支持标准的ANSI SQL语句外,最重要的是,它还支持多种平台,而在Unix/Linux系统上,MySQL支持多线程运行方式,从而能获得相当好的性能。它和前两个软件一样,是属于开放源代码软。
二、MySQL的安装(指Windows版本)
将下载后的文件解压,到一个目录,运行Setup程序,会提示整个安装的过程。它默认安装到c:mysql下,如果要安装到其它目录下还有改动一些东西,作为初学者,可以先不管,以默认的目录安装。好了,安装后,进入c:mysqlin目录下,运行mysqld-shareware.exe文件
在Win98下直接运行,正常情况下,没有什么提示信息
在NT下可以输入:mysqld-shareware --install 启动该服务
接着,输入mysql ,正常情况下会出现几行提示信息并出现下提示符号:
mysql>
到此,你已经成功安装了MySQL。
三、设置MySQL用户密码
MySQL数据库的默认用户名为“root”(MS SQL Server 的 sa 相似),密码默认为空。在DOS提示符(注意,不是mysql提示符)下输入
c:mysqlin>“mysqladmin -u root -p password adminpassword
回车后会提示你输入原来的密码,由于原来密码为空,直接回车,root用户的密码便改为“adminpassword”了。
四、简单使用MySQL数据库
1.显示MySQL的数据库(注意:在该文的以后部分,如果没有提示,输入的命令都是在mysql提示符下)
show databases
2.打开一个数据库
use test
其中,test为数据库名称
3.显示一个数据库中所有数据表 (必须先打开一个数据库)
show tables
go
4.以root身份创建一个数据库(在DOS提示符号下)
mysqladmin -u root -p password adminpassword create gsbook
接着会提示你输入密码。因为,我们的目的是做一个留言板,我在这里将数据库的名称命名为“gsbook”。
5.在数据库中加入数据表
create table gsbook(id int not null auto_increment,primary key(id),nickname varchar(30),email varchar(30),homepage varchar(30),note text,w_time datetime)

In Laravel development, dealing with complex model relationships has always been a challenge, especially when it comes to multi-level BelongsToThrough relationships. Recently, I encountered this problem in a project dealing with a multi-level model relationship, where traditional HasManyThrough relationships fail to meet the needs, resulting in data queries becoming complex and inefficient. After some exploration, I found the library staudenmeir/belongs-to-through, which easily installed and solved my troubles through Composer.
