DataGrip使用入门

阅读更多关于 DataGrip使用入门

最近看到一款数据库客户端工具，DataGrip，是大名鼎鼎的JetBrains公司出品的，就是那个出品Intellij IDEA的公司。DataGrip是一款数据库管理客户端工具，方便连接到数据库服务器，执行sql、创建表、创建索引以及导出数据等。之前试用的客户端工具是dbvisualizer，但是在试用了DataGrip以后，我就决定抛弃dbvisualizer。我相信，当你第一眼看到DataGrip以后，会有一种惊艳的感觉，就好比你第一眼看到一个姑娘，就是那么一瞥，你对自己说，就是她了！废话不多说，来看看DataGrip的常用功能。DataGrip下载链接如下 https://www.jetbrains.com/datagrip/download 。安装过程也很简单，双击安装，下一步，中间会让你选择主题，本人选择的是经典的Darcula，安装完成后，启动，界面如下相信使用过IDEA的同学会感到很亲切。接下来管理数据库驱动。DataGrip支持主流的数据库，File->DataSource 也可以在Database视图中展开绿色的+号，添加数据库连接选择需要连接的数据库类型在面板中，左上部分列出了已经建立的数据库连接，点击各项，右侧会展示当前连接的配置信息，General面板中，可以配置数据库连接的信息，如主机、用户名、密码等，不同数据库配置信息不完全相同，填入数据库URL
