To inquire about index information in the MySQL database, you can use the following two methods:

  1. To display the index information of a table, use the “SHOW INDEX” command. For example, to query the index information for the “students” table, you can execute the following command:
SHOW INDEX FROM students;

This command will return a result set containing information such as index name, index type, index fields, and index order.

  1. To utilize the INFORMATION_SCHEMA database: MySQL offers a database called INFORMATION_SCHEMA which includes information about various metadata in the system. To query index information, you can use the following query statement:
SELECT * FROM INFORMATION_SCHEMA.STATISTICS WHERE table_schema = 'your_database_name' AND table_name = 'your_table_name';

Replace “your_database_name” with your database name and “your_table_name” with your table name. This query will return index information related to the specified table, including index name, index type, index fields, and index order.

Before performing these queries, it is necessary to have sufficient permissions to access the metadata of the database and tables.
