MySQL Transaction

Using MySQL you can COMMIT a statement and ROLLBACK to manage transaction.

While adding a data into two or more tables where one primary key for one table is the foreign key of another table it may happen sometimes that after adding data into first table MySQL failed to add data into second table due to database failure.

Due to this reason transaction came which enables to execute a set of operations. If one failure occurs then the rollback occurs to restore the database.

Example of Transaction:

start transaction;

insert into users(user_id,name,status)
values(1, 'John Doe', 25);

insert into orders(order_id,user_id,order_items)
values(1, 1, 'Watch');

commit;
