SQL queries proceed through several steps during execution. This video delves into the SQL query execution order, including how the database optimizer determines the sequence of operations to achieve optimal performance. Elaborate on query parsing, binding, plan creation, and execution. Understanding these steps is vital to write and optimize complex queries.

Additionally, diving into real-world examples will clarify various concepts. We suggest studying query optimization techniques like query rewrites, indexing, and join orders to yield proficient results.
