SQL Server View refers to a virtual table. Although it is virtual, it still has the normal parts of a table, which are rows and columns. A user can do many things with a view. He can retrieve data and update this in a view. He can also use the view to get real tables in the database, join the two tables and present them as a single table. This is very useful for ad-hoc reporting. SQL Server View can also be used as a security mechanism. This works by restricting the data that end users can access. SQL Server View can also aggregate and partition data.

How SQL Server View works?

SQL Server View as said before is a virtual table and therefore the database does not store the view data. The user can instead retrieve data from a view that the database engine recreates. The database stores the definition of the view but not the data itself. This is an advantage because this doesn’t take so much space.

When To use SQL Server View?

A user must already have a goal in mind when creating a view. These goals might include the following:

First, it might be to simplify or customize the data and schema for certain users in mind. A business needing ad-hoc reporting tool can take advantage of SQL Server View because it customizes reports to support its goals. A business can use it to know more details about an order without looking at the tables for product and order information.

Second, it might be to control access to rows and columns of data or it can be to aggregate data.

SQL Server View is a convenient tool for businesses making it easier for them to make decisions.
