What is the table creation statement in mysql

The table creation statement in mysql is [CREATE TABLE table_name (column_name column_type);]. For example, you can create a new "phpcn_tb" table through the syntax [CREATE TABLE `phpcn_tb`].

Common SQL syntax for creating MySQL data tables:

CREATE TABLE table_name (column_name column_type);

(Recommended tutorial: mysql tutorial)

Example:

CREATE TABLE `phpcn_tb`(
   `phpcn_id` INT UNSIGNED AUTO_INCREMENT,
   `phpcn_title` VARCHAR(100) NOT NULL,
   `phpcn_author` VARCHAR(40) NOT NULL,
   `submission_date` DATE,
   PRIMARY KEY ( `phpcn_id` )
)ENGINE=InnoDB DEFAULT CHARSET=utf8;

Explanation:

If you don’t want the field to be NULL, you can set the attribute of the field to NOT NULL. When operating the database, if the data entered in this field is NULL , an error will be reported.

AUTO_INCREMENT is defined as an auto-incrementing attribute, generally used for primary keys, and the value will automatically increase by 1.
