Example 4: mysql create table

Imaginons que l’ont souhaite créer une table utilisateur,
contenant "id","nom", "prenom", "email", "date_naiss", "pays" etc..
La requête pour créer cette table peut ressembler à ceci:

Voici des explications sur les colonnes créées :

    id : identifiant unique qui est utilisé comme clé primaire
		 et qui n’est pas nulle
    nom :une colonne de type VARCHAR avec un maximum de 100 caractères 
    prenom : idem mais pour le prénom

  Age int,
  Class varchar(15));

Example 6: MySQL CREATE TABLE

The CREATE TABLE statement allows you to create a new table in a database.

The following illustrates the basic syntax of the CREATE TABLE  statement:

CREATE TABLE [IF NOT EXISTS] table_name(
   column_1_definition,
   column_2_definition,
   ...,
   table_constraints
) ENGINE=storage_engine;
Let’s examine the syntax in greater detail.

First, you specify the name of the table that you want to create after the CREATE TABLE  keywords. The table name must be unique within a database. The IF NOT EXISTS is optional. It allows you to check if the table that you create already exists in the database. If this is the case, MySQL will ignore the whole statement and will not create any new table.

Second, you specify a list of columns of the table in the column_list section, columns are separated by commas.

Third, you can optionally specify the storage engine for the table in the ENGINE clause. You can use any storage engine such as InnoDB and MyISAM. If you don’t explicitly declare a storage engine, MySQL will use InnoDB by default.
