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 Help needed! Subquery on one table in Sql server 2000.** Kind of urgent **

Asked by tgatif in MS SQL Server

Tags: , , ,

I have one table and i want a subquery or a scalar subquery within same table:

ID, CODE, effdt                 COLLEGE  COMMENTS
1   0     2005-09-19               S        1K
1   0     2006-03-19             W        2K
2   0     2005-10-19             M        3K
2   1     2005-11-19             S        3K
3   0     2005-10-20             M        4SK
3   1     2006-01-19              S        4SK
3   2     2006-01-10              S       4XK
3   2     2005-12-19             M        GK

id, code, effdt and college are keys

I am looking to write a query which will tell me identify dupliacete code in multiple colleges for one emplid.
in this case one example is ID 1. It has code of 0 in both college S and college W. In my query I want to identify only those records which have duplicate codes in different college with effective dated.

So when i write my query i should see

ID, CODE, effdt                 COLLEGE  COMMENTS
1   0     2006-03-19               W        2K
3   2     2006-01-10             S       4xK


So in above, I got 2 Ids which had multiple code values in two differnet colleges. I got the most recent (effdt) out of those with the college name, code, ID and the comments

I have written sub blurbs that give me the IDs but it doesnt give me effdt.
A sample effdt query is written as

select flda, fldb, effdt from table 1
where effdt = (select max(a.effdt) from table 1 a where
a.flda = flda and a.fldb = fldb)
