8. Database & Table Coding
 Create database if not exists
Gourmet_Foods_Company;
 Create table if not exists
Gourmet_Foods_Company.Continent
( Cont_ID int(20) auto_increment primary key,
Cont_Name varchar(50) not null )

9. Views
• In SQL, a view is a virtual table based on the
result set of an SQL statement
• A view contains rows and columns, just like a
real table
 create view view_name AS SELECT
column_name from
database_name.table_name;

11. Joins
• An SQL JOIN clause is used to combine
rows from two or more tables, based on a
common field between them
 SELECT column_name(s) FROM table1
INNER JOIN table2 ON
table1.column_name =table2.column_name

12. Stored-Procedure
• A stored procedure is a set of SQL
statements that can be stored in the server
• It is a method to encapsulate repetitive
tasks
• They allow for variable declarations, flow
control and other useful programming
techniques

13. Syntax
 DELIMITER //
Create procedure show_continent()
Begin
Select *from
gourmet_foods_company.continent;
END //

14. Triggers
• Kind of stored procedures
• Use only for DML commands
• It fires automatically when these actions are
attempted
Institute of Southern Punjab

15. Syntax
 DELIMITER //
CREATE trigger insertlocation after insert on location for
each row
BEGIN
insert into gourmet_foods_company.location VALUES
('@Loc_ID','@Loc_Name','@Loc_Country','@Loc_State','
@Loc_City');
END //

16. Indexes
• Use for sorting record
• Create a sorted virtual copy
• Faster for efficient searching
 CREATE INDEX index_name ON
database_name.table_name(column_name);
