计算视图中的结果数

Question

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?

Answer 1

Here's a good do 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.)

Answer 2

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:

1. Add fields for the criteria that you want to GROUP BY .
2. Add the SQL Aggregation field as the last field (or swap it into the last).
3. Choose the fields (you can select multiple fields) Fields to Group On .
4. SQL Aggregation Function should be set to Count .
5. Fields to Aggregate with the SQL function set to a field that you are not grouping by. (This will be added into the COUNT function like COUNT(<this field>) in SQL)
6. The rest is up to you and click Update .

You should have the COUNT output from the field that you selected to aggregate.
