Answer / Vikram Maheshwari

Common Table Expressions (CTEs) and Views are both used in SQL Server to simplify complex queries, but they have some key differences. A CTE is defined within a SELECT, INSERT, UPDATE, or DELETE statement and is only visible for the duration of that execution. It's temporary and can reference other CTEs and tables. On the other hand, a View is a stored query that contains a SELECT statement. It can be used as a table in an SQL statement. The main difference lies in their scope and lifetime: a CTE exists only for the duration of a single execution, while a View persists until it's dropped.
