A view is a virtual table in SQL that is created from the result set of a SQL operation. A view is similar to a table in that it has rows and columns. Fields from one or more real tables in the database are used in views.
In SQL, there are two sorts of views: simple and complex. Only one base table can be used in simple views. More than one basis table can be used to create complex views. Complex views, in instance, can have join criteria, a group by clause, and an order by clause.
In SQL Server, a VIEW is a virtual table that holds data from one or more tables. It does not contain any data and does not exist in the database physically. The view name, like the name of a SQL table, should be unique in the database. It includes a set of SQL queries for retrieving data from the database.
A user must have the required system privilege according to the specific implementation to create a view. CREATE A VIEW WITH THE NAME view name FROM table name SELECT column1, column2,.... WHERE [condition]; In a SELECT statement, you can use many tables in the same way you would in a normal SQL SELECT query.
A table is made up of rows and columns that are used to store and arrange data in a structured manner, whereas a view is a collection of SQL commands. A view is a virtual table extracted from a database, whereas a table is structured with columns and rows.

Why you didn't teach/learn how to write select query, even you shared 15 question for practice :(
I have found the course to be interesting with plenty of valuable information provided as part of the course and through interaction with fellow teachers and trainers from a wide range of disciplines
