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 queries

Asked by YZlat in MS SQL Server

Tags: queries, combine, two

I have two queries that are almost identical except the second one has only those records from first query where t1.detected > 0.
The data displayed by the queries below is

Group_Id      Name      totalCount
1      1 Test        380
2      2 Test       126
3      3 Test       245      

and

Group_Id      Name      detectedCount
1      1 Test        121
2      2 Test       103
3      3 Test       84      

SELECT t3.Group_Id, t4.Name, COUNT (distinct (t1.record_id)) as totalCount
                  from Table1 t1, Table2 t2, Table3 t3, Table4 t4
                  WHERE t1.id = t2.id and t1.lang = t2.lang and t4.Group_Id = t3.Group_Id and t4.Name LIKE '%Test'
                  and t2.Test_Id = t3.Test_Id
                  AND t3.ParentGroup_Id = 2 group by t3.Group_Id, t4.Name

SELECT t3.Group_Id, t4.Name, COUNT (distinct (t1.record_id)) as detectedCount
                  from Table1 t1, Table2 t2, Table3 t3, Table4 t4
                  WHERE t1.detected > 0 t1.id = t2.id and t1.lang = t2.lang and t4.Group_Id = t3.Group_Id and t4.Name LIKE '%Test'
                  and t2.Test_Id = t3.Test_Id
                  AND t3.ParentGroup_Id = 2 group by t3.Group_Id, t4.Name


I want to combine two queries above to display the results as follows:

Group_Id                      Name        totalCount            detectedCount
1            1 Test        380                       121
2            2 Test       126                   103
3            3 Test       245                    84

Is that possible?
