24. Set 8: STORED PROCEDURES
Definition:
It is a routine of set of pre-defined SQL statements that takes action on data in database when called.
Used to execute set of SQL statements which is more likely to use again and again
Bypasses some of the steps while executing series of SQL statements repeatedly
It is like user defined function in OOP language.
Also commonly known as ‘sproc’
Advantages:
Improves performance by storing execution plan of SQL statements
Code stored as data in database so it is easy to maintain and back-up with data
Simplifies administration and maintenance in large database project
Logic reusability can be achieved through store procedure
Provide different level of access to different user
Control access to underlying data and structure
Prevents certain actions from damaging database and data in it

25. Set 8 : Cont’ed…
Following is Stored Procedure to make deposit into account
To Create Store Procedure
DELIMITER //
CREATE DEFINER=`root`@`localhost` PROCEDURE `proc_deposit`(amountx int, accountIDx int)
main:BEGIN
insert into transactiondetail (transactiontimestamp, transactionAmount,AccountID, transactionbalance)
values (now(), amountx, accountIDx, transactionamount+(select mydb.accountdetail.CurrentBalance from
mydb.accountdetail where accountid=accountIDx));
leave main;
end //
delimiter ;
To run Store Procedure CALL command is used
call proc_deposit(1000,1);
To Drop Store Procedure
drop procedure proc_deposit;

26. Set 8 : Cont’ed…
Following is Stored Procedure to make withdrawal from account
To create Stored Procedure
DELIMITER //
CREATE DEFINER=`root`@`localhost` PROCEDURE `proc_withdrawl`(amountx int, accountIDx int)
main:BEGIN
insert into transactiondetail (transactiontimestamp, transactionAmount,AccountID, transactionbalance)
values (now(), amountx, accountIDx, 0-transactionamount+(select TransactionBalance from
mydb.transactiondetail where TransactionID=(select max(TransactionID) from transactiondetail where
AccountID=accountIDx)));
leave main;
end //
delimiter ;
To Run and Drop Stored Procedure
call proc_withdrawl(1000,1);
drop procedure proc_withdrawl;

27. Set 9: TRANSACTIONS- Commit, Rollback, Savepoint,
Rollback To Savepoint
>> Start transaction;
>> call proc_deposit(1000,1);
>> savepoint sp1;
>> call proc_deposit(1000,21);
>> rollback to savepoint sp1;
>> commit;
>> select * from transactiondetail;
START TRANSACTION is used to begin transaction
It increases performance drastically
SAVEPOINT allows to define saving point in transaction
ROLLBACK TO SAVEPOINT allow to rollback a transaction to
specific savepoint mentioned
COMMIT is used to terminate a transaction and to save all
changes in the Database

28. Set 10: TRIGGERS
TRIGGER: It is similar to Stored Procedure but can’t call explicitely. It is reaction to action
performed on table.
create table customer (cID int, cname varchar(45), corderID int, primary key(cID));
create table invetory (invID int, prodID int, cID int,quant int, price int, primary key(invID));
insert into customer values (1,'USA', 123456789);
insert into customer values (2,'China', 912346789);
insert into customer values (3,'India', 812345789);
insert into invetory values (1,812345789, 3, 6, 15);
select * from customer;
select * from invetory;
Query to create TRIGGER:
create trigger newinvetory after insert on inventory
for each row
update customer set corderid=new.invid
where cid=new.cid;
NOW, TRIGGER will be fired after INSERT
insert into invetory values (2,55555, 2, 8, 50);
Before Trigger get fired
After Trigger get fired

29. Set 11: VIEW
VIEW: A virtual table whose definition is stored in the database but that does not actually contain data.
It is a basically SELECT statement stored as a named object.
Query to create VIEW : View_CustomerPersonal
create view `View_CustomerPersonal` as
select cust.CustomerID,cust.CustomerFirstName as `First Name`, cust.CustomerLastName as `Last Name`, cust.CustomerBirthdate as
`Date of Birth`, cust.CustomerSSN as `Social Security`, cust.CustomerOccupation as Occupation, custAddr.CustomerAddress as
`Address Line`, custAddr.CustomerContact as `Contact`, zip.City, zip.State, zip.Country

35. Monthly Back Up Plan: Full and Incremental Backup
Assumptions:
1. Every data generated is important to Bank for analysis and support.
2. Bank works 6 days/week in which Saturday is Half day working
3. Bank prefers weekly auditing of all accounts
4. Full back-up takes more time than incremental back-up
Back-Up Plan for Banking:
1.For the first time, full back of system will be taken
2. Then each day from Monday through Friday daily incremental back-up will be done
3. As working hours are half on Saturday, weekly full back-up will be covered
4. After every two week, one full back-up is planned to reduce monthly back-up load
4. Towards end of month, on nearest Saturday Full Last month back-up will be taken
5. Process will be repeated every month and in the end of year, yearly back-up will be covered.
Back-Up Schedule for complete 1 month is on the next slide….
