How can I list all indexes in a table in MYSQL?

Question

How can I insert data into one table from two other tables where i have three tables namely users, role and userrole.
Now I want to insert the data into userrole table from users table and role table with a single statement.

Answer 1

To see the index for a specific table use SHOW INDEX:

SHOW INDEX FROM yourtable;

To see indexes for all tables within a specific schema you can use the STATISTICS table from INFORMATION_SCHEMA:

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

Removing the where clause will show you all indexes in all schemas.

Answer 2

select * from mysql.statistics ;
