# MySQL Admin
# 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:
CREATE TABLE new LIKE real; load `new` by whatever means - LOAD DATA, INSERT, whatever RENAME TABLE real TO old, new TO real; DROP TABLE old;
# 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.
DROP database as a SQL Script (you will need DROP privilege on that database):
DROP DATABASE database_name
DROP SCHEMA database_name
