MySQL Programming Interview Question:

How To Get a List of Indexes of an Existing Table?

Submitted by: Administrator

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

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