Exporting MySQL results to a file is a common task for database administrators and developers. It allows you to save the data for further analysis, reporting, or backup purposes. In this guide, I will walk you through the process of exporting MySQL results to a file using the command line. Whether you are using a Unix-based system or Windows, the steps are quite similar.
Understanding the Basics
Before diving into the command line instructions, it’s essential to understand some basic concepts:
- MySQL Command Line Tool (mysql): This is the primary tool used to interact with MySQL databases from the command line.
- SELECT Statement: This is used to retrieve data from a MySQL database.
- Output File: The file where you want to save the exported data.
Now that you have a basic understanding of the terms, let’s move on to the actual process.
Exporting Data to a CSV File
CSV (Comma-Separated Values) is a popular format for exporting data. It is widely supported and can be opened in various spreadsheet applications like Microsoft Excel or Google Sheets.
Here’s how to export MySQL results to a CSV file:
- Open your command line interface.
- Log in to your MySQL server using the following command:
- Once logged in, use the following command to export the data:
- Replace
username
with your MySQL username,database_name
with the name of your database,path/to/your/file.csv
with the path to the output file, andtable_name
with the name of the table you want to export. - Press Enter, and the data will be exported to the specified CSV file.
mysql -u username -p database_name
SELECT INTO OUTFILE 'path/to/your/file.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '' FROM table_name;
Here’s an example of the entire process:
mysql -u myuser -p mydbEnter password: SELECT INTO OUTFILE '/home/myuser/data.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '' FROM my_table;
Exporting Data to an SQL File
Another common format for exporting data is SQL. This format is useful if you want to import the data into another MySQL database or for backup purposes.
Here’s how to export MySQL results to an SQL file:

- Log in to your MySQL server using the following command:
- Once logged in, use the following command to export the data:
- Replace
username
with your MySQL username,database_name
with the name of your database, andpath/to/your/file.sql
with the path to the output file. - Press Enter, and the data will be exported to the specified SQL file.
mysql -u username -p database_name
SELECT FROM table_name INTO OUTFILE 'path/to/your/file.sql' LINES TERMINATED BY '';
Here’s an example of the entire process:
mysql -u myuser -p mydbEnter password: SELECT FROM my_table INTO OUTFILE '/home/myuser/data.sql' LINES TERMINATED BY '';
Exporting Data to Other Formats
MySQL supports exporting data to various other formats, such as Excel, PDF, and XML. To export data to these formats, you can use the following commands:
