MySQL ISSHOW - SQL

Introduction

As a programmer or a database administrator, you would have come across the situation where you need to show the structure of a table. MySQL ISSHOW - SQL statement can be useful in such cases.

"ISSHOW" is a MySQL specific command that allows you to retrieve the structure of a table. The structure includes column names, data types, and other attributes.

Syntax

ISSHOW table_name;

Example

Consider the following example where we have a table named "customers" with six columns:

CREATE TABLE customers (
    id INT(11) NOT NULL AUTO_INCREMENT,
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL,
    gender ENUM('male', 'female') NOT NULL,
    date_of_birth DATE NOT NULL,
    PRIMARY KEY (id)
);

To show the structure of the "customers" table, we can use the following command:

ISSHOW customers;

The output of the command would be:

| Field | Type | Null | Key | Default | Extra | |---------------|---------------|--------|------|---------|-----------------| | id | int(11) | NO | PRI | NULL | auto_increment | | first_name | varchar(50) | NO | | NULL | | | last_name | varchar(50) | NO | | NULL | | | email | varchar(100) | NO | | NULL | | | gender | enum('male','female') | NO | | NULL | | | date_of_birth | date | NO | | NULL | |
