• Time to save your precious work:

  mysqldump -u root -p my_test_db > my_test_db.out

• Now drop the table

  mysql>drop table table1;

• Now drop the whole database my_test_db:

  mysql>drop database my_test_db;

• create the db again:

  mysql>create database my_test_db;

• Replay the backup

  mysql -u root -p my_test_db < my_test_db.out

We're through, check the clock.
Btw: If you're going to be asked what SQL stands for, don't disgrace yourself. It means: Structured Query Language.

If you'll get this one:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

then you've already set the password, and need to use the -u for user and the -p for password switch.
