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,

 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

techniques

insert into gourmet_foods_company.location VALUES
('@Loc_ID','@Loc_Name','@Loc_Country','@Loc_State','
@Loc_City');
END //
