What is the difference between a view and a stored procedure in SQL?
View is simple showcasing data stored in the database tables whereas a stored procedure is a group of statements that can be executed. A view is faster as it displays data from the tables referenced whereas a store procedure executes sql statements.
Which is better stored procedure or view?
In general, a Stored Procedure stands a good chance of being faster than a direct SQL statement because the server does all sorts of optimizations when a stored procedure is saves and executed the first time. A view is essentially a saved SQL statement.

Are views faster than queries?
A view is nothing more than a stored query definition, there is no caching or storing of data for a view. The optimiser will effectively turn your first query into your second query when you run it. In my finding, using the view is a little bit faster than a normal query.
What is an example of stored procedure?
A stored procedure is a group of SQL statements that form a logical unit and perform a particular task, and they are used to encapsulate a set of operations or queries to execute on a database server. For example, operations on an employee database (hire, fire, promote, lookup) could be coded as stored procedures executed by application code.
