Above all, you should know that the Structured Query Language or SQL is a query language that allows you to make queries or queries on a database management system or SGBD. A database table has a unique name and is generally composed by columns and rows. If you are a custom php application development user, here's how to create a table in SQL with PHP.
The table liste_owner
Let us first create the table is liste_owner table_liste_owner.sql.
CREATE TABLE liste_owner (
number INT (5) NOT NULL,
name varchar (20) NOT NULL,
phone varchar (14) NOT NULL
) TYPE = MyISAM; .
Here we then create a liste_owner table that contains three attributes including the number which will correspond to an integer (INT) 5 digits, a name that corresponds to a esuite character (VARCHAR) of 20 characters and phone that will match a character string (VARCHAR) of 14 characters.
VARCHAR is used here to strings that can contain both text and numbers. For any attribute can not be empty, we have NOT NULL for all. The type MyISAM, meanwhile, has the role to clarify that we are here dealing with a MySQL database.
The table liste_disque
The table_liste_disque.sql will be composed by
CREATE TABLE liste_disque (
number INT (5) NOT NULL,
author varchar (50) NOT NULL,
title varchar (50) NOT NULL,
) TYPE = MyISAM.
The attributes are almost identical as that of the first table. However we have been able to use the extra AUTO_INCREMENT number for attributes in the first table. This will then prevent us each time specify the new owner of the number. This extra will thus enable us to automatically increment each time you insert a new owner.
The table liste_owner will be defined as follows:
CREATE TABLE liste_owner (
number INT (5) NOT NULL AUTO_INCREMENT,
name varchar (20) NOT NULL,
VARCHART phone (14) NOT NULL,
PRIMARY KEY (number)
) TYPE = MyISAM;
Here PRIMARY KEY (number) will indicate the number attribute. It is then possible for us to identify all tuples of the table from him.
The creation of this table is from PHPMyAdmin. However, it is also possible to do it directly from a php page but this is not ideal for beginners.
