What are the limitations of using MySQL views?

Although there are various benefits of using views, there are still the following limitations when using MySQL views-

• Cannot create a view view index- In MySQL, we cannot create indexes on views. This is because when we query data against the view, no index is used.
• MySQL invalidates the view - Suppose, if we drop or rename the table referenced by the view, instead of issuing an error MySQL invalidates the view. We can use the CHECK TABLE statement to check if the view is valid.
• MySQL views cannot be updated in some cases - In fact, simple views can be updated, but views created on complex SELECT statements using JOIN or SUBQUERY cannot be updated.
• MySQL does not support materialized views - We cannot create materialized views because MySQL does not support it.
• Using subqueries in the FROM clause of the view depends on the MySQL version -In fact, if the MySQL version is lower than 5.7.7, we can use the subquery in the FROM clause of the view Inquire.
• Cannot create a temporary view -Actually, the definition cannot reference a temporary table, so we cannot create a temporary view.
• Unable to associate triggers with views -We cannot associate triggers with views.
