This tutorial is based on the CTE in SQL concept. CTE in SQL stands for Common Table Experssions. The CTE in SQL begins with the WITHkeyword in SQL. the CTE in SQL acts as an intermediate or temp table in SQL that stores the intermediate results of a sub query helping to minimise the code length and query execution time.

What does with CTE do in SQL?
A Common Table Expression (CTE) in SQL is a temporary result set that can be referenced within a SELECT, INSERT, UPDATE, or DELETE statement. CTEs are defined using the WITH keyword and allow you to create a named, reusable subquery within your SQL statement.

Is CTE better than subquery?
When choosing between CTEs and subqueries, consider the specific use case. For one-off calculations or when dealing with small data sets, subqueries may be preferable. For repeated references to an intermediate result or when readability is a priority, CTEs might be the better choice.
