Editor to share with you how to write the mysql creation table command, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The following information is required to create an MySQL data table:

● table name

● table field name

● defines each table field

Basic grammar

The following is the general SQL syntax for creating MySQL data tables:

CREATE TABLE table_name (column_name column_type)

Example: create a table from the command prompt

You can easily create an MySQL data table through the mysql > command window. You can use the SQL statement CREATE TABLE to create a data table.

1. First connect to the mysql server and enter the password

Root@host# mysql-u root-pEnter password:*

2. Enter the database RUNOOB

Use RUNOOB

3. Create a table

Mysql > CREATE TABLE runoob_tbl (- > runoob_id INT NOT NULL AUTO_INCREMENT,-> runoob_title VARCHAR (100) NOT NULL,-> runoob_author VARCHAR (40) NOT NULL,-> submission_date DATE,-> PRIMARY KEY (runoob_id)->) ENGINE=InnoDB DEFAULT CHARSET=utf8

Output:

Query OK, 0 rows affected (0.16 sec)

Indicates that the datasheet was created successfully.

Note: the MySQL command Terminator is a semicolon;.

Note:-> is a newline identifier, do not copy.

Example parsing:

● if you do not want the field to be NULL, you can set the property of the field to NOT NULL. If you enter the data of the field as NULL when operating the database, you will report an error.

The ● AUTO_INCREMENT definition is listed as a self-increasing attribute, which is generally used for primary keys, and the value is automatically incremented by 1.

The ● PRIMARY KEY keyword is used to define column primary keys. You can use multiple columns to define the primary key, separated by commas.

● ENGINE sets the storage engine and CHARSET sets the encoding.

We can use the command to view the command line to view the table structure
