How do I get the execution plan for a view? I have a schema with a number of views.  I need to check the execution plans to make sure the appropriate indexes are in place and being used.

How do I do this?

I'd rather not have to copy and paste the output from show create view &lt;viewname&gt; into explain, especially as some of the views are built on top of other views and this would be quite a pain.
Use the information_schema.views table
This will generate the EXPLAIN for all views
mysql -uroot -p -AN -e&quot;select concat('explain ',view_definition) from information_schema.views&quot; &gt; /root/ExplainViews.sql

This will generate the EXPLAIN for all views in the mydb database
mysql -uroot -p -AN -e&quot;select concat('explain ',view_definition) from information_schema.views where table_schema = 'mydb'&quot; &gt; /root/ExplainViews.sql

Give it a Try !!!

@MattFenwick, your answer is a whole lot simpler than mine. Here is an example I tried out on my PC running MySQL 5.5.12. I ran EXPLAIN on both the SELECT version from your answer and the EXPLAIN generated from my answer:
mysql&gt; explain select * from bigjoin;
+----+-------------+-------+--------+---------------+---------+---------+---------------+------+-------------+
| id | select_type | table | type   | possible_keys | key     | key_len | ref           | rows | Extra       |
+----+-------------+-------+--------+---------------+---------+---------+---------------+------+-------------+
|  1 | SIMPLE      | k     | index  | NULL          | PRIMARY | 4       | NULL          |   14 | Using index |
|  1 | SIMPLE      | a     | eq_ref | PRIMARY       | PRIMARY | 4       | test.k.id_key |    1 | Using index |
|  1 | SIMPLE      | b     | ALL    | NULL          | NULL    | NULL    | NULL          |    4 |             |
+----+-------------+-------+--------+---------------+---------+---------+---------------+------+-------------+
3 rows in set (0.00 sec)

mysql&gt; explain select `a`.`id_key` AS `id_key1`,`b`.`id_key` AS `id_key2` from ((`test`.`idlist` `k` left join `test`.`id_key_table` `a` on((`k`.`id_key` = `a`.`id_key`))) left join `test`.`new_keys_to_load` `b` on((`k`.`id_key` = `b`.`id_key`)));
+----+-------------+-------+--------+---------------+---------+---------+---------------+------+-------------+
| id | select_type | table | type   | possible_keys | key     | key_len | ref           | rows | Extra       |
+----+-------------+-------+--------+---------------+---------+---------+---------------+------+-------------+
|  1 | SIMPLE      | k     | index  | NULL          | PRIMARY | 4       | NULL          |   14 | Using index |
|  1 | SIMPLE      | a     | eq_ref | PRIMARY       | PRIMARY | 4       | test.k.id_key |    1 | Using index |
|  1 | SIMPLE      | b     | ALL    | NULL          | NULL    | NULL    | NULL          |    4 |             |
+----+-------------+-------+--------+---------------+---------+---------+---------------+------+-------------+
3 rows in set (0.00 sec)

mysql&gt;

They both produced the same EXPLAIN plan. I will change my answer to implement your way. You get a +1 from me although it's +2 for simplicity. You should go ahead and accept your own answer on this one.
Here is an interesting factoid about VIEWs in MySQL : A view is represented in two places in the information_schema database

information_schema.views : table_schema,table_name identify, and view_definition
information_schema.tables : table_schema,table_name where ENGINE is NULL

This will generate the EXPLAIN for all views
mysql -uroot -p -AN -e&quot;select concat('explain select * from ',table_schema,'.',table_name,';') from information_schema.tables WHERE engine IS NULL&quot; &gt; /root/ExplainViews.sql

or
mysql -uroot -p -AN -e&quot;select concat('explain select * from ',table_schema,'.',table_name,';') from information_schema.views&quot; &gt; /root/ExplainViews.sql

This will generate the EXPLAIN for all views in the mydb database
mysql -uroot -p -AN -e&quot;select concat('explain select * from ',table_schema,'.',table_name,';') from information_schema.tables WHERE table_schema='mydb' AND engine IS NULL;&quot; &gt; /root/ExplainViews.sql

or
mysql -uroot -p -AN -e&quot;select concat('explain select * from ',table_schema,'.',table_name,';') from information_schema.views WHERE table_schema='mydb';&quot; &gt; /root/ExplainViews.sql
