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!

Pivot the data into weeks

Asked by seazodiac in MS SQL Server

Tags: pivot

Data sample in original format:
key           date_worked                             hours
11      2005-01-04 00:00:00.000      8.00
11      2005-01-05 00:00:00.000      8.00
11      2005-01-06 00:00:00.000      8.00
11      2005-01-07 00:00:00.000      8.00
11      2005-01-03 00:00:00.000      8.00
11      2005-01-17 00:00:00.000      8.00
11      2005-01-18 00:00:00.000      8.00
11      2005-01-19 00:00:00.000      8.00
11      2005-01-20 00:00:00.000      8.00
11      2005-01-21 00:00:00.000      8.00
11      2005-01-24 00:00:00.000      4.00
11      2005-01-25 00:00:00.000      8.00
11      2005-01-26 00:00:00.000      8.00




Need to transform into this:


key           week 1                        week 2                                   week 3            week 4
11            total_hours in week 1   total in week2                       total in week3      total in week 4




keep in mind while ironing out a solution:
1.  I simplified the example so it only has one key value, there might other values for the key 11, 23, 12, 34, etc, so it has to be grouped by key

2. the week count is from the first day of the current year (ignore any week prior to this year) up until the current date (which is getdate() value).


500pts goes to the early birds.
