Do you know index can be added to MySQL view?
Thanks
Sadly, you can't. You can index the tables the view is based on.
Also, see this question: Is it possible to have an indexed view in MySQL?
Nope.
For more information about indexes and MySQL view performance, read this question.
However, you can use some tricks. Add custom_id field to view and put value of "hash" of another unique field in same row :D
In my case i combine category id and article id
