Creating CSV Backups from MySQL via Command Line
Dumping a MySQL database into a CSV backup can be achieved through various methods. Here are two approaches that can be executed from the command line:
1. Using the MySQL Client with -B Option
For tabular data, the -B option in the mysql command allows you to generate TSV (tab-separated) files. These files can be easily imported into Excel or other spreadsheet programs:
% echo 'SELECT * FROM table' | mysql -B -uxxx -pyyy database
In this command, xxx and yyy represent the MySQL username and password, respectively.
2. Using SELECT INTO OUTFILE
If you have server-side access, you can employ the SELECT INTO OUTFILE statement to create CSV files directly:
SELECT * INTO OUTFILE 'table.csv' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM table
This statement generates a CSV file named table.csv with the specified formatting options.
