Question: What Is Difference Between Views And Stored Procedures?

When should I use stored procedures and when should I use views in SQL Server?

Views should be used to store commonly-used JOIN queries and specific columns to build virtual tables of an exact set of data we want to see.

Stored procedures hold the more complex logic, such as INSERT, DELETE, and UPDATE statements to automate large SQL workflows..

What is the difference between function and stored procedure?

What is the use of stored procedures?

What is a Stored Procedure? A stored procedure is a prepared SQL code that you can save, so the code can be reused over and over again. So if you have an SQL query that you write over and over again, save it as a stored procedure, and then just call it to execute it.

Are views faster than queries?

Views make queries faster to write, but they don’t improve the underlying query performance. … In short, if an indexed view can satisfy a query, then under certain circumstances, this can drastically reduce the amount of work that SQL Server needs to do to return the required data, and so improve query performance.

Where are views stored?

View is a simple SQL statement that is stored in database schema (INFORMATION_SCHEMA. Views). So when ever we call the view the SQL statement gets executed and return the rows from main physical table. You can also tell the view as a Logical table that store the defination (the sql statement) but not the result.
