How To Get a List of Indexes of a Given Table in MySQL?

A

If you want to see the index you have just created for an existing table, you can use the "SHOW INDEX FROM tableName" command to get a list of all indexes in a given table. The tutorial script below shows you a nice example:

mysql> SHOW INDEX FROM TIP;
+------------+-------------+--------------+-------------+...
| Non_unique | Key_name    | Seq_in_index | Column_name |...
+------------+-------------+--------------+-------------+...
|          0 | PRIMARY     |            1 | id          |...
|          1 | tip_subject |            1 | subject     |...
+------------+-------------+--------------+-------------+...
2 rows in set (0.03 sec)

It's interesting to see that there is a default index for the primary key column.
