select
    table_name,
    index_name,
    seq_in_index,
    column_name,
    non_unique,
    index_type,
    comment
from
    information_schema.statistics
where 1=1

    and table_name = 'my_table'
order by 1,2,3,4,5,6

查询数据库中所有已禁用的索引

SELECT INDEX_SCHEMA, COLUMN_NAME, COMMENT 
FROM information_schema.statistics
WHERE table_schema = 'mydb'
AND COMMENT = 'disabled'

如果你想一次性查看所有数据库的所有索引:

use information_schema;
SELECT * FROM statistics;

如果我们知道下面的索引名，我们可以直接看到表上的索引:

Select * from all_indexes where index_name= 'your index'

您可以使用此查询来获取指定数据库中每个表的索引名和索引号。

SELECT TABLE_NAME,
       COUNT(1) index_count,
       GROUP_CONCAT(DISTINCT(index_name) SEPARATOR ',\n ') indexes
FROM INFORMATION_SCHEMA.STATISTICS
WHERE TABLE_SCHEMA = 'mydb'
      AND INDEX_NAME != 'primary'
GROUP BY TABLE_NAME
ORDER BY COUNT(1) DESC;

在我的例子中，这适用于在对应的表中获取索引字段的表名和列名。

SELECT TABLE_NAME , COLUMN_NAME, COMMENT 
FROM information_schema.statistics
WHERE table_schema = 'database_name';
