How can I output MySQL query results in CSV format?


Is there an easy way to run a MySQL query from the Linux command line and output the results in CSV format?

Here's what I'm doing now:

mysql -u uid -ppwd -D dbname << EOQ | sed -e 's/        /,/g' | tee list.csv
select id, concat("\"",name,"\"") as name
from students
EOQ

It gets messy when there are a lot of columns that need to be surrounded by quotes, or if there are quotes in the results that need to be escaped.


Solution

  • From Save MySQL query results into a text or CSV file:

    SELECT order_id,product_name,qty
    FROM orders
    WHERE foo = 'bar'
    INTO OUTFILE '/var/lib/mysql-files/orders.csv'
    FIELDS TERMINATED BY ','
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n';
    

    Note: That syntax may need to be reordered to

    SELECT order_id,product_name,qty
    INTO OUTFILE '/var/lib/mysql-files/orders.csv'
    FIELDS TERMINATED BY ','
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'
    FROM orders
    WHERE foo = 'bar';
    

    in more recent versions of MySQL.

    Using this command, columns names will not be exported.

    Also note that /var/lib/mysql-files/orders.csv will be on the server that is running MySQL. The user that the MySQL process is running under must have permissions to write to the directory chosen, or the command will fail.

    If you want to write output to your local machine from a remote server (especially a hosted or virtualize machine such as Heroku or Amazon RDS), this solution is not suitable.
