How Can I Find and View Indexes in My MySQL Database?

Finding Indexes in a MySQL Database

In managing a MySQL database, it's essential to understand the usage of indexes to optimize query performance. To view the indexes associated with a specific table, utilize the SHOW INDEX command:

SHOW INDEX FROM yourtable;

This command displays detailed information about each index, including its name, column(s) involved, and type.

For a broader view, you can inspect indexes across all tables within a specific schema using the INFORMATION_SCHEMA:

SELECT DISTINCT
    TABLE_NAME,
    INDEX_NAME
FROM INFORMATION_SCHEMA.STATISTICS
WHERE TABLE_SCHEMA = 'your_schema';

Modifying the 'your_schema' placeholder with the desired schema name will limit the results to that specific schema. Omitting the WHERE clause will display all indexes in all schemas.
