Answer 1

This one works for me in MySQL 5, and it is specific to tables:

echo 'show tables' | mysql --skip-column-names -u root YOUR_DB | awk '{print "truncate table " $0 ";"}' | mysql -u root YOUR_DB

Replace YOUR_DB by the name of your database. You have to provide your password twice, so you have a chance to think it again ... ;-)
