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!

Warning: Null value is eliminated by an aggregate or other SET operation.

Asked by WATYF in MS SQL Server

Tags: , , , ,

I keep getting this "warning" when I run certain scripts:

Warning: Null value is eliminated by an aggregate or other SET operation.


It's not a "fatal" error, so the script still runs, but it does kick out a message to my users, which I need to find a way around.

Here's an example of one of the scripts that gerenates this warning.


      insert into #cte select [description], userfield1 as [sku], userfield2 as [cust] from series where scenarioid = @lm and (userfield1 <> '' or userfield2 <> '')
      delete from #cte where exists (select sku, customer from series sr where sr.sku = #cte.sku and sr.customer = #cte.cust and scenarioid=5960)
      delete from #cte where exists (select sku, customer from series sr left join observations ob on sr.seriesid = ob.seriesid where sr.sku = #cte.sku and sr.customer = #cte.cust and sr.scenarioid = @lm and sr.levelnum <> 0 group by sku, customer having sum(ob.uservalue01)>0)


The warning occurs as a result of the line:

delete from #cte where exists (select sku, customer from series sr left join observations ob on sr.seriesid = ob.seriesid where sr.sku = #cte.sku and sr.customer =


It has something to do with nulls being in the dataset that's getting summed... but I don't know how to account for the nulls so that I don't get this message. Any ideas?
