Exercise 2
1. Create a new database called
‘Flight_Management’

2. Use SQL Query Analyzer to work with Flight_Management database and create a SQL
script file follow those steps:
1. Create tables and insert data as follows:
Flight
Column Name Data Type Length Allow Nulls
Aircraft_code char 5
Aircode char 2
Type varchar 10
Source varchar 15
Destination varchar 15
Category varchar 15
Dep_time varchar 15 x
Journey_hrs int 4 x
Flight_details
Column Name Data Type Length Allow Nulls
Aircraft_code char 5
Class_code char 2
Fare numeric 5
Seats numeric 5
Flight_days
Column Name Data Type Length Allow Nulls
Aircraft_code char 5
day_code int 4
insert the following data into tables
Flight table
Aircraft_code Aircode Type Source Destination Category Dep_time Journey_hrs
9W01 9W Airbus Cal Che D 15.30 3

9W02 9W Airbus Mum Del D 9.30 2
9W03 9W Airbus Che Mum D 10.45 2

Constraints (Student must use ‘Alter Table’ statement to Apply them)
1. Apply the Default Constraint to the Type column of Flight table with value is
Airbus.
2. Apply the Primary Key Constraint for Aircraft_code of Flight table, and the
Composite Primary Key Constraint for the Aircraft_code and Class_code of the
Flight_details table.
3. Create a References Constraint between Flight table and Flight_details table on
Aircraft_code named ‘FK_Contr1’

2. Display total number of domestic flight (Category=‘D’)
3. Display flight detail has fly at Monday (day_code =2)

4. Create a view named ‘Flight_List’ as following: (the list must sorted by Aircode, Type,
ClassCode, Fare, Daycode)
Aircode Type ClassCode Fare Daycode
9W Airbus Fx 5000 1
9W Airbus Fx 5000 2
9W Airbus Fx 5000 1
AI Boeing Ec 4500 2
AI Boeing Ec 4500 1
5. Modify the view named ‘Flight_List’ such that you can create an index on it. (Hint: Add
‘With SchemaBinding’ option)

6. Create an index named ‘indFlight_List’ on the (‘Aircode,’ ClassCode) column of the
‘Flight_List’ view.
7. Display flight details that has Fare = 5000

8. Drop References Constraint between Flight table and Flight_details
9. Create an Delete Trigger named ‘tgDeleteAll’ on the Flight table to prevent you from
deleting a row has Aircarft_code =’9W01’ and display a notice ‘You can not
delete’
10. Create a stored procedure named ‘spDropFlight’ that accept an Aircode as parameter.
The stored procedure will delete all Flight which has the Aircode like
parameter
Notes: You must ensure that this action will completely.
