Getting Table Names in MySQL Using SELECT Statements: A Comprehensive Guide

While MySQL doesn't have a single, dedicated `SELECT` statement to directly return a list of table names, you can leverage the `information_schema` database and its `TABLES` table to achieve this. This guide provides a comprehensive walkthrough of how to retrieve table names using `SELECT` statements in MySQL, along with examples and explanations.

*1. Understanding `information_schema`*

`information_schema` is a virtual database in MySQL that provides metadata about the MySQL server instance. It doesn't store actual data; instead, it exposes information about databases, tables, columns, privileges, and more. It's crucial for introspection and dynamic database management. You have read-only access to this database and cannot modify its content.

*2. The `TABLES` Table in `information_schema`*

Within `information_schema`, the `TABLES` table is our primary resource for retrieving table names. This table contains a row for each table (and view) accessible to the current MySQL user. Key columns relevant to our task include:

*`TABLE_SCHEMA`:* The name of the database the table belongs to.
*`TABLE_NAME`:* The name of the table.
*`TABLE_TYPE`:* Indicates whether it's a `BASE TABLE` (a regular table), `VIEW`, `SYSTEM VIEW`, or `TEMPORARY`.
*`ENGINE`:* The storage engine used by the table (e.g., InnoDB, MyISAM).

*3. Basic `SELECT` Statement to List All Tables*

The simplest way to get a list of all tables accessible to your current user is to query the `information_schema.TABLES` table.



This query selects only the `TABLE_NAME` column from the `information_schema.TABLES` table, effectively returning a list of all table names in all databases accessible to the user.

*4. Filtering by Database (Schema)*

To retrieve tables from a specific database, you need to add a `WHERE` clause to filter by the `TABLE_SCHEMA` column. Replace `'your_database_name'` with ...
