How do I show the schema of a table in a MySQL database?

How to Show the Schema of a Table in a MySQL Database 💻🗄️

Whether you're a seasoned MySQL user or just starting out, showing the schema of a table in your database can sometimes be a little tricky. But fear not! In this guide, we'll break down the process and provide you with easy solutions to tackle this common issue. Let's dive in! 🤿

The Problem 😕

So, you're sitting at your MySQL console, staring at your table, and wondering how to display its schema. Seems simple, right? Well, the command to use might not be as straightforward as you'd think.

The Solution ✅

To display the schema of a table in a MySQL database, you can use the DESCRIBE or SHOW COLUMNS FROM command. Both of these commands achieve the same result, so it's up to you to choose your preferred syntax.

Using the DESCRIBE Command 📝

DESCRIBE table_name;

For example, if you have a table called users, you would use the following command to display its schema:

DESCRIBE users;

This command will provide you with a table-like output, showing the column names, data types, nullability, and additional details for each column in the table.

Using the SHOW COLUMNS FROM Command 🗄️

SHOW COLUMNS FROM table_name;

If you prefer a slightly different syntax, you can use the SHOW COLUMNS FROM command. The result will be the same as when using the DESCRIBE command.

For our users table example, the command would be:

SHOW COLUMNS FROM users;

This command will also display the same information: column names, data types, nullability, and additional details.

Example Output 🖥️

To help you visualize the process, here's an example of the output you can expect when using either the DESCRIBE or SHOW COLUMNS FROM command:

+---------+--------------+------+-----+---------+----------------+
| Field   | Type         | Null | Key | Default | Extra          |
+---------+--------------+------+-----+---------+----------------+
| id      | int(11)      | NO   | PRI | NULL    | auto_increment |
| name    | varchar(100) | YES  |     | NULL    |                |
| age     | int(11)      | YES  |     | NULL    |                |
| email   | varchar(255) | YES  |     | NULL    |                |
+---------+--------------+------+-----+---------+----------------+

Easy, right? 👌
