How to list all indexes in MySQL database? In this article, you will learn several ways to get a list of all indexes in a MySQL database.
1. Using SQL Query
To start with, we will use an SQL query to get a list of all indexes in the MySQL database. The following SQL script will help you get all indexes:

If you are looking to list all indexes of a specific table the SQL query to run is as follows.
SELECT table_schema, table_name, index_name, column_name

AND table_name= ‘your_table_name’,
