Navicat的使用

需要掌握的使用操作

#1. 测试+链接数据库

#2. 新建库

#3. 新建表，新增字段+类型+约束

#4. 设计表：外键

#5. 新建查询

#6. 建立表模型

#注意：

批量加注释：ctrl+？键

批量去注释：ctrl+shift+？键

运行sql文件 建表

前期数据准备：

# 导出的sql语句代码:

运行sql文件 快速建表

# 可视化界面操作方法

1、将上述代码保存到 .sql 文件中

2、在Navicat中右键选则建表的目标数据库

3、选择右键菜单中的 运行SQL文件

4、弹出文件框，找到刚刚保存的 .sql 文件打开 执行即可

# sql语句运行 .sql 文件来快速建表

1、将上述代码保存到 .sql 文件中

2、在Navicat中的sql语句输入界面 输入sql语句：

3、

mysql> create database db1;

mysql> use db1;

mysql> source /root/init.sql # source 后跟的是 .sql 文件路径
