What is the golden rule of SQL?
Can you enlighten us on the golden rule of SQL? Is it a principle that governs all aspects of SQL programming, or does it focus on a specific aspect, such as query optimization or data integrity? We're curious to know how this rule can help developers and database administrators alike in their daily tasks, and what practical applications it has in real-world scenarios. Perhaps you can provide an example or two to illustrate the golden rule in action, and how it can lead to more efficient and effective SQL practices.
