Sometimes when we use mysql database, we want to import a txt text document. How to do it? The following article will introduce the method to you, I hope it will be helpful to you.

1. Prepare data and create a test table

1. Prepare the txt text document that needs to be imported. The path is: c :/data.txt.

Use the Tab key to separate each item. If the field is NULL, use /N to indicate it.

2. Create a new database and a table. The fields designed in the table need to correspond to the number of columns in the imported text document.

Example: Create a table representing student information for testing. The fields include id, name, age, city, and salary. Id and name cannot be empty.

create table person(
id int not null auto_increment,
name varchar(40) not null,
city varchar(20),
salary int,
primary key(id)
)engine=innodb charset=gb2312;

The screenshot of the created table is as follows:

2. Import data

Enter the command to import:

load data local infile “c:/data.txt”  
into table person(name,age,city,salary);

The screenshot of the imported data is as follows:

where local means local. After execution, you can see that NULL data is also imported correctly.

3. Export data

Now export this table to a text file: c:/data_out.txt.

select name,age,city,salary  
into outfile “c:/data_out.txt”  
lines terminated by “/r/n”  
from person;

The screenshot of the exported data is as follows:

where lines terminated by “/r/n” means that each line (i.e. each record) uses /r/ n separates, /r/n is the newline character of the window system. The contents of the exported data_out.txt are exactly the same as data.txt.
