问题
I need to count how many people belong in pre-defined groups (this is easy to do in SQL using the SELECT COUNT statement). My Views query runs fine and displays the actual data in my table, but I simply need to know how many results it found.
However there doesn't seem to be a COUNT option in views. I am guessing I am going to have to use some sort of views hook, and then stick the result in the table.
Here's a quick example of what i'm trying to achieve:
My Table
----------------------
Group A | 20 people
Group B | 63 people
and so on.
(I've tried using the Views_Calc module, but I get errors because it is not quite stable yet.)
Anybody know of an easy way to count results in Views?

Here's a good d.o thread about it: http://drupal.org/node/131031
Although if you JUST need the count and not the other things Views offers (field formatting & ordering, etc), why not just code up the proper SELECT COUNT statement and call it a day?
(If you DO in fact need those other pieces Views offers, there are many examples on that thread above.)

I'm currently using the Views Group By module for this type of functionality.
I'm actually working on adding other aggregate functions (MIN, MAX, etc.) into it but since you only need the COUNT function, I think it's a pretty good option.
All you have to do (after installing and enabling the module), in the View that you are interested:
- Add fields for the criteria that you want to
GROUP BY. - Add the SQL Aggregation field as the last field (or swap it into the last).
- Choose the fields (you can select multiple fields)
Fields to Group On. SQL Aggregation Functionshould be set toCount.- Fields to
Aggregate with the SQL functionset to a field that you are not grouping by. (This will be added into theCOUNTfunction likeCOUNT(<this field>)in SQL) - The rest is up to you and click
Update.
You should have the COUNT output from the field that you selected to aggregate.
