Can you elaborate on what is meant by the 'rule hint' in SQL? I'm interested in understanding how it can be used to potentially optimize query performance or manage database behavior. Are there any specific examples of how rule hints might be applied in a real-world scenario? Additionally, are there any limitations or considerations I should be aware of when utilizing rule hints in my SQL coding practices?

While the CBO is generally recommended for its ability to analyze various execution plans and choose the most cost-effective one, the RBO might still be relevant in specific use cases.
