How to create and use a SQL Server view?

To create a view, you can use the CREATE VIEW statement. The basic syntax of this statement is as follows:

“Establish a view named view_name that selects column1 and column2 from table_name based on a specific condition.”

Here, view_name is the name of the view, column1, column2, … are the columns to be selected, table_name is the table from which data is to be selected, and condition is an optional filtering condition.

Here’s an example demonstrating how to create a view called “customers_view”, selecting the columns “cust_id” and “cust_name” from a table named “customers”, and only choosing rows where “cust_id” is greater than 100.

Make a view called customers_view that includes customer ID and customer name from the customers table, but only for customers who have an ID greater than 100.

To utilize this view, you can query it just like you would a table. For example, you can use a SELECT statement to retrieve data from the view.

Retrieve all information from the customers_view.

This will return all rows and columns in the view.

It is important to note that views do not store actual data, but instead select and return data from tables. Therefore, the data in views is dynamic, meaning that when the data in the underlying tables changes, the data in the views will also be updated accordingly.
