The reason why it has this option turned on is because when creating indexes on views, they actually physically get stored in the database. Notice that this view has a WITH SCHEMABINDING option on it.
Without further ado, let’s create a view using the CREATE VIEW SQL statement from below and see what it does: They are a great tool for DBAs and developers when it comes to finding and fixing a bottleneck in the slow running query. Furthermore, to explain the pros of indexed views, we’ll be looking at executions plans in SQL Server.

But the general idea, as the title says, is to see how to work with indexed views, see what the requirements are for adding an index to a view, and how to do it programmatically. We will, of course, use the CREATE VIEW SQL statement for this as we did many times through the series. The first thing that we’ll do is create an indexed view. So, head over and read those before continuing with this one. Here are the previous three pieces of the CREATE VIEW SQL series:
This is primarily because we created our own sample database and objects in it from scratch that we’ll be using in this part too, but also because it will be much easier to see the big picture. In this last part, I want to take a big look at how to work with indexed views.Īs always, to follow along with the series, it’s highly recommended to read the previous parts first and then this one. So far, we have done a great deal of creating and altering views using T-SQL. This is the fourth article in a series of learning the CREATE VIEW SQL statement.
