What are the limitations of using MySQL views?

In spite of various benefits of using views there are following limitations on using MySQL views −

Can’t create an index of views − In MySQL, we cannot create an index on views. It is because indexes are not utilized when we query data against the views.
MySQL invalidates the view − Suppose, if we drop or rename tables to which a view references, rather than issuing an error MySQL invalidate the view. We can use the CHECK TABLE statement to check whether the view is valid or not.
MySQL views cannot be updateable in some situations − Actually, the simple view can be updateable but a view created on a complex SELECT statement with JOIN or SUBQUERY etc. cannot be updateable.
MySQL does not support materialized views − We cannot create materialized views because MySQL does not support it.
Using subquery in the FROM clause of view depends on MySQL version − Actually, we can use a subquery in the FROM clause of view if MySQL version is less than 5.7.7.
Cannot create a TEMPORARY view − Actually, the definition cannot refer to a TEMPORARY table hence we cannot create a TEMPORARY view.
Cannot associate a trigger with a view − we cannot associate a trigger with a view.
