Atomic RENAME & Table Reload

RENAME TABLE t TO t_old, t_copy TO t;

No other sessions can access the tables involved while RENAME TABLE executes, so the rename operation is not subject to concurrency problems.

Atomic Rename is especially for completely reloading a table without waiting for DELETE and load to finish:

load `new` by whatever means - LOAD DATA, INSERT, whatever
RENAME TABLE real TO old, new TO real;

Change root password

mysqladmin -u root -p'old-password' password 'new-password'

Drop database

Useful for scripting to drop all tables and deletes the database:

mysqladmin -u[username] -p[password] drop [database]

Use with extreme caution.

To DROP database as a SQL Script (you will need DROP privilege on that database):

DROP DATABASE database_name


DROP SCHEMA database_name
