CSV Database Backups via Command Line
While mysqldump provides a convenient backup option for MySQL databases, its output format may not be universally accessible. This article explores alternative methods for creating plaintext CSV backups from the command line, offering greater flexibility.
Using MySQL's '-B' Option
For table-by-table exports, MySQL's '-B' option can generate TSV (tab-separated) files. These files can be easily imported into various applications such as Excel. To use this method:
% echo 'SELECT * FROM table' | mysql -B -uxxx -pyyy database
Replace 'table' with the desired table name, 'xxx' with the username, 'yyy' with the password, and 'database' with the database name.
Using 'SELECT INTO OUTFILE'
This method requires direct access to the server's file system and generates true CSV files. To use 'SELECT INTO OUTFILE':
SELECT * INTO OUTFILE 'table.csv' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM table
Remember to adjust the file path in 'table.csv' and ensure that the necessary permissions are in place for the file creation.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
