Question

Here is my scenario,

I have query that returns a lot of fields. One of the fields is called ID and I want to group by ID and show a count in descending order. However, since I am bringing back more fields, it becomes harder to show a true count because I have to group by those other fields. Here is an example of what I am trying to do. If I just have 2 fields (ID, color) and I group by color, I may end up with something like this:

ID COLOR COUNT

== ===== =====

2    red     10

3    blue     5

4    green   24

Lets say I add another field which is actually the same person, but they have a different spelling of their name which throws the count off, so I might have something like this:

ID COLOR NAME COUNT

== ===== ====== =====

2    Red    Jim      5

2    Red    Jimmy      5

3    Red    Bob      3

3    Red    Robert      2

4    Red    Johnny      12

4    Red    John      12

I want to be able to bring back ID, Color, Name, and Count, but display the counts like in the first table. Is there a way to do this using the ID?

Answer 1

If you want a single result set, you would have to omit the name, as in your first post

SELECT Id, Color, COUNT(*) FROM YourTable GROUP By Id, Color 

Now, you could get your desired functionality with a subquery, although not elegant

SELECT Id, Color Name, (SELECT COUNT(*)                          FROM YourTable                          Where Id = O.Id                              AND Color = O.Color                        ) AS 'Count' FROM YourTable O GROUP BY Id, Color, Name 

This should work as you desire
