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!

Combine two SQL queries in a cfquery

Asked by lepirtle in Cold Fusion Markup Language

Tags: , , , ,

I am using MS Access and Coldfusion to create a cfquery that will output a list containing the number of miles that users have accumulated during a current year and list those users and their accumulated miles, in descending order with a ranking number of 1 for the user with the most miles.

tbl_mileusers has 2 fields: userkey and username.
tbl_miles has 4 fields: userkey, milesdate, and miles.

Using Access' Query Design mode, I have created two queries:
qry 1 reads:
SELECT tbl_mileusers.username, Sum(tbl_miles.miles) AS SumOfmiles
FROM tbl_mileusers INNER JOIN tbl_miles ON tbl_mileusers.userkey = tbl_miles.userkey
GROUP BY tbl_mileusers.username;

qry 2 reads:
SELECT myqry2.username, myqry2.SumOfmiles, (Select Count(*) from myqry1 Where [Sumofmiles]>[myqry2].[SumOfmiles])+1 AS Ranking
FROM myqry1 AS myqry2
ORDER BY myqry2.SumOfmiles DESC;

Running qry2 in Access produces exactly the output that I want. However, qry2 requires using qry1 in its SQL statement and I do not know the proper syntax to combine the 2 queries into 1 SQL statement which I need to construct my <cfquery>. (At least I assume that I need only 1 SQL statement to create a <cfquery> because I do not know any other way to create a cfquery).

Might someone provide me with the correct SQL to use to create my cfquery?

I am a beginner at this so if I am missing something obvious I appreciate your patience.
Thanks
Lee
