商业软件
在这里插入图片描述

带有自动补全,连接远程数据库,应有尽有,面配置
考虑支持正版

dataGrip (database plugin of IDEA)

jetbrain家的产品,有社区版?
以智能著称
可以在IDEA中安装插件来实现功能

IDEA (Ultimate ) plugin for database

点击market进行搜索并安装:
在这里插入图片描述

基本使用

添加单个数据库到列表中:

添加多个或者全部可用的数据库(模式设定)

这里推荐只将需要操作的书库看添加到工作空间中即可,避免分散注意力

sql console查询

在这里插入图片描述

vscode(免费系列搭建)

mysql extension for vscode

MySQL client

此插件现已转为收费插件
- 免费版有许多操作限制
- 截至4.6.0版本是免费版(推荐,可以禁止插件自动跟新)
install and user manual

插件mysql 插件配置(功能打开)

在这里插入图片描述

mysql shell for vscode

MySQL Shell for VS Code - Visual Studio Marketplace
允许您使用mysql shell,同时提供补全功能
如果要创建多个链接,可能需要重启vscode(bug)

mysql 补全插件:(mysql autocomplete)

浏览数据库/执行脚本

(可有可无(可以被mysql client )替代)

总体使用体验还是不错的.

最终的工作空间视图

在这里插入图片描述

mysql环境

确保mysql环境可用

可以是远程主机的mysql 数据库
也可以是本地的mysql数据库

新手安装mysql数据库(phpStudy)

可以考虑使用小皮(phpStudy)来安装并控制数据库
界面简单,安装配置迅速

环境变量配置

mysql:
- 软件安装位置查询:(可以将相关目录配置到环境变量以及将相关路径写入到Path变量,这样方便你在终端中直接输入mysql命令直接获取相关的sql服务

检查配置效果

新开一个终端,执行如下操作验证
- 密码根据在小皮面板中配置的来输入即可
- 未配置情况下,密码可能为空(直接enter),也可能为root
-

安装mysql服务

注意,如果想要使用小皮面板来管理,就不要安装mysql服务
如果你不再想依赖小皮面板来管理数据库,那么可以通过
mysqld.exe --install来安装服务:
(安装完以后如果以下命令无法顺利执行,可以注销(重启)计算机,然后重试)

检查/启动mysql服务运行

powershell下检查服务:
gsv *sql*

在管理模式下方可启动服务

重新检查mysql 服务运行状态

在这里插入图片描述

说明

安装完服务,就无法利用phpstudy来管理数据库了
但是您可以通过删除服务来重新启用phpstudy管理数据库

vscode+extension建立链接到数据库

在这里插入图片描述
管理/查看连接

在这里插入图片描述

在工作空间中编写sql查询脚本/新建sql查询

在工作目录下编写的脚本在运行前需要确保于sql服务建立connection
如果已经建立,尝试重载窗口来刷新状态.再尝试执行脚本

关于mysql (client)插件的版本更新

2022.mysql client 插件推出收费版,限制了免费版的一些功能

插件适用情况

本插件比较适合操作非空数据库(或者说有可操作的数据库的连接,数据库的可见性和可用性和用户的权限相关)
如果某个连接中的可用数据库为空,那么可以通过如下方式新建一个数据库

注意,新建数据库/表的用户需要具有相应的权限!否则创建失败
刚授权的用户可能需要重启机器才能够使得权限生效
把[name]改为你想要的名字

新建一个表

在这里插入图片描述

执行mysql脚本的方式

激活连接到数据库

执行sql脚本的时候,需要选择一个连接作为当前的执行对象

譬如为数据库创建表,如果没有选定指定的数据库,那么可能失败,也可能在不想要的地方(其他数据库内)创建了表
旧版插件的截图:
较新版本的选择做了二级分层,先选中连接,在选中数据库
- 默认是以主机名@端口名作为连接选择

在这里插入图片描述

经过功能配置后,可以显示连接名

检查当前激活的用户/数据库

在执行脚本的时候,明确用户和被操作数据库是很重要的
查询当前用户
- select user();
查询当前使用的数据库
- select database();
切换使用的数据库
- use <database_name>;
也可以通过下方状态栏选择;

执行脚本(方式1:inline按钮,执行指定sql 语句块)

分段/渐进式执行

执行脚本方式2:(command palette):

执行所有sql查询

Note:脚本执行顺序

不同的运行方式在执行脚本中的sql 查询时会产生不同的效果
一般的,run all sql按顺序执行脚本内容,其他的方式会执行指定段落的sql query;需要考虑上下文(比如某些语句所依赖的表是否被创建完)

右侧按钮也是执行局部代码段(需要考虑上下文)

插件执行快捷键配置:

可以为同一个指令配置多个触发快捷键
(特别是在您的默认快捷键已经被其他命令占用)
或则也可以修改被占用快捷键所绑定的when条件

交互操作数据库

text Editor+GUI viewer

数据库操作历史(命令记录)

查看表中数据

在这里插入图片描述

查看字段

在这里插入图片描述

生成测试数据并填充到表

生成测试数据前建议刷新一下数据库连接,如果在其他地方修改过数据库字段,可能导致mock时获取的字段滞后,所以建议刷新后再mock
mock生成的测试数据可能可以调整范围
