The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Query, view and table optimization

Asked by WarrenBarrett in SQL Query Syntax, MySQL Server, Databases Miscellaneous

Tags: Sun, MySQL, 5.0.27, SQL

I am trying to optimize the 2 queries below (one of them is a view), but I cant figure out how to get it to use the indexes I have set up.
The queries are run a minimum of 900 times every 2 minutes, so I would like them to be as optimized as possible.
I have included all the relevant tables so you can see how I have set everything up. I dont know if it matters, but the only table that is updated regularly is tblflightdata (every 2 minutes it is truncated and repopulated with new data), the other 3 tables are updated relatively infrequently.
In the bottom query: 'USA5286' is unique, 'JFK' could be one of 2 values (currently, may be higher at a later date, but probably not more than 10 values), the last value is always 'U'.
I have also included the result of an EXPLAIN executed on the query (which uses the view).

Hope you can help,
Thanks
