Common Table Expressions (CTEs)

A Common Table Expression, also known as CTE, is a named temporary result set that can be referenced within a SELECT, INSERT, UPDATE, or DELETE statement. CTEs are particularly helpful when dealing with complex queries, as they enable you to break down the query into smaller, more readable chunks. Recursive CTEs are helpful when working with hierarchical or tree-structured data.
