Views are the primary way of accessing data in databases. A deleted view is one that has been removed from the database. This article will explain what a deleted view is and how soon it can be restored.
Understanding Deleted Views
A view is a virtual table that is created from the result set of a query. It is used to store the results of a query and can be used to query the underlying tables. Views are used to simplify the process of querying data and to hide the underlying structure of the database.
When a view is deleted, it is permanently removed from the database. This means that the view and its associated data are no longer available. The data in the view is also lost, which can be problematic if the data is needed.
In some cases, the view can be recreated from the underlying tables. However, this can be a complex process and can take a significant amount of time.
Restoring Deleted Views
Views can be restored in a variety of ways. One of the most common methods is to use a database backup. Database backups are copies of the database that can be used to restore the view. The process of restoring the view from a backup is relatively straightforward and can usually be done within a few minutes.
Another method of restoring a deleted view is to use a database recovery tool. These tools are designed to scan the database and identify deleted objects, such as views. They can then be used to restore the view to its original state. This process can take a few hours, depending on the size of the database.
Finally, the view can be recreated from the underlying tables. This can be a complex process and can take a significant amount of time, depending on the complexity of the view.
In conclusion, deleted views can be restored in a variety of ways. The most common methods are using a database backup or a recovery tool. Depending on the method used, a deleted view can usually be restored within a few hours.
