Inline View || Analytical Functions in Oracle SQL Day - 36
n Oracle SQL, an inline view, also known as a derived table or subquery factoring, is a named subquery in the FROM clause of a main query. It allows you to create a temporary result set that can be treated as a table, enabling you to perform further operations on it as if it were an actual table.
Inline views are useful when you need to perform complex calculations, aggregations, or filtering on data before joining it with other tables or incorporating it into the main query. They can make complex queries more readable and manageable by breaking down the logic into smaller, modular parts.

Analytical functions in Oracle SQL are powerful tools that allow you to perform advanced data analysis and computations over a set of rows in a result set. These functions help you gain insights into your data by providing additional information without the need for complex self-joins or subqueries. Analytical functions are typically used in conjunction with the SELECT clause and can be partitioned and ordered to customize their behavior.
