Question

I was wondering how to delete the values in a MySQL database table from bash.

I have a database called “database” and a table in that database called “table”.

Now I want to dump and clear the database from a bash script.

How can I delete the values?

I am using:

mysqldump database > $DB_BACKUP/01/table-`date +%Y-%m-%d` (to dump)

and now trying to

DELETE FROM database.table WHERE filed < CURDATE()-5

Answer 1

mysql -Bse 'DELETE FROM database.table WHERE filed < CURDATE()- 5'

or

mysql -Bse 'DELETE FROM table WHERE filed < CURDATE()- 5' database

mysql --help

-B, –batch Don’t use history file. Disable interactive behavior.

-s, –silent Be more silent. Print results with a tab as separator,
