Which of these is NOT a method of optimizing your AMC SQL?


Explanation: The correct answer is **Adding redundant subqueries** because adding redundant subqueries is not a method of optimizing AMC SQL. In fact, redundant subqueries can negatively impact the performance of the query by introducing unnecessary complexity and computational overhead. Redundant subqueries do not add value to the data being retrieved and can slow down the query execution time. On the other hand, methods like optimizing the query’s order of operations, filtering records early in the query, and optimizing JOIN conditions are all effective techniques for improving the efficiency of SQL queries. These methods help reduce the volume of data being processed, ensure the query executes in the most efficient manner, and minimize the time it takes to retrieve the desired results.
