    Why don't you open another thread asking what an explain plan is, how to have the database spit it out and, last but not least, how to read it?
    Can anybody explain me what PLAN is good for? Please don't tell me to go and read the documentation in the ApiGuide or such. I would like to hear the main reasons why should i use a PLAN, and how does it make my life easier?

    The explain plan of a query shows you how the database server executes a query.
    It is extremely useful to troubleshoot slow queries and check index usage.

    You can see it at work in this blog post.
