In this article, we would like to show you how to create a table if not exists in MySQL.

Quick solution:

CREATE TABLE IF NOT EXISTS `table_name` (
    `column1` DATA_TYPE,
    `column2` DATA_TYPE,
    `column3` DATA_TYPE,
    ...
);

Note:

Go to the official documentation to see available DATA_TYPES.

Practical example

In this example, we create users table with the following columns and types:

  • id - INT,
  • name - VARCHAR,
  • role - VARCHAR. 

Query:

CREATE TABLE IF NOT EXISTS `users` (
    id INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
    name VARCHAR(100) NOT NULL,
    role VARCHAR(15) NOT NULL,
    PRIMARY KEY (id)
);
