Record the problem of mysql database importing data in different formats.
Recently, I am learning from other people's websites (how can the things of scholars be called copying), and I need to import the data into my own database bit by bit. At first, I felt that the data was quite small, so I typed sql commands line by line to import a little bit. Later, I felt that it was too slow. Anyway, I am a half-hearted programmer, and manual import is too low-level.
So I wrote a crawler (life is short, learn python quickly) to crawl the desired data, save it in a file, and then use the import function that comes with mysql to import the data into my table.
I won’t talk about crawling data, let’s talk about several methods of importing external data.
.sql file
As mentioned before, this file format is relatively simple to import
mysql -u root -p wordpress < /usr/local/wordpress.sql #这句意思是把wordpress.sql文件导入到wordpress数据库中
Only one command is needed to import successfully.
.txt file
This is an ordinary file format, and it is the same under Linux with or without a file suffix.
Suppose the file format is as follows

Each field is separated by ',' . Of course, other separators can also be used for separation. The separator is preferably one that does not appear in your data.
Use the following command to import it into a table in the database.
load data local infile "/home/date" into table workonline FIELDS TERMINATED BY ',';
此命令含义是把/home/data里面的数据导入到当前数据库里的workonline表里，每个字段以‘,’分开
