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!

SQL for Grouping and Ordering

Asked by BoggyBayouBoy in SQL Server 2005, MS SQL Server

I have a table that has project tasks.  The tasks have parent-child relationships.  For example:  

Developing Phase consists of 2 tasks: coding, unit testing
Testing Phase consists of 2 tasks: conduct acceptance test, and fix bugs

the data looks like so:
Task,                         Level1,                         TaskIndex,   taskWork
-----------------------,   -------------------------,   --------,   --------
Developing Phase, Developing Phase,         1,                0
Coding                  , Developing Phase,         2,               10
Unit Testing          , Developing Phase          3,                5
Testing Phase,      Testing Phase                4,                0
Conduct Acceptance Test, Testing Phase,  5,         15
Fix Bugs,                Testing Phase  ,                6            10

I want a query that will return 2 results:  the sum of all the work in Developing Phase, and sum of work in Testing Phase.  like so:

Developing Phase, 15
Testing Phase, 25

I also want it ordered by Task Index (which is a problem).  What I have is this:

select
a.Level1,
sum(a.work)
from table a
group by  a.Level1

Of course as soon as I add an additional element, I get more than 2 results, and I don't know how to do the sort.
