Data visualization learning (2)------Visualization practice of Excel or ECharts (sakila database)

First, mysql loads the Sakila sample database

• Download: http://downloads.mysql.com/docs/sakila-db.tar.gz
• Unzip: Put the unzipped files into a directory
• Use the following command in mysql:

• > source E:/sakila-schema.sql;（此处为自己的安装路径）
  

•  >source E:/sakila-data.sql;(注意路径上的名称为英文，改成“\”)
  

• select count(*) from custormer; if hundreds of records are displayed, the import is successful
  

Second, get data

• Using SQL statements, connect the customer_list table and the payment table to get the consumption amount of each consumer in each city
• select city,country from country,city,customer where country.country_id=city.country_id and city.city_id=customer.address_id;
