count(*) and ORDER by the result of count

Hi everyone,

Ok I want here to make a query which will reuse the result of a count(*) function.


lets say my website does events at different places for the same date, and also at different dates:
this makes a structure like this:
Expand|Select|Wrap|Line Numbers
  1. event_id | attending_id | date 
there may be for the SAME date:
-multiple records with the same event_id and different attending_id
("different attendants to the same event for a specific date")
-multiple records with different event_id and different attending_id
("different attendants are going to different events the same date")

repeat these two possibilities for different dates

i could have:
Expand|Select|Wrap|Line Numbers
  1. date1 - john - best poker
  2. date1 - bob  - best poker
  3. date1 - pip  - best poker
  4. date1 - ron   - poker unite
  5. date1 - clo   - poker unite
  6. date1 - foo   - poker unite
  7. date1 - fos   - poker unite
  8. date1 - koh   - gold poker
  9. date2 - ron   - poker unite
  10. date2 - bob  - poker unite
  11. date3 - bob  - poker unite
  12. data3 - mar  - poker hacks
i would like to count the number o attendants for each event at a specific date.

Expand|Select|Wrap|Line Numbers
  1. SELECT count(*)
  2.         FROM attending 
  3.         WHERE attending.date = '$date'
  4.         ORDER by the most populated events 
i would like to get:
(for date1)
Expand|Select|Wrap|Line Numbers
  1. poker unite 4
  2. best poker 3
  3. gold poker 1
is there a way to perform this?


PD: in my real table the events are stored under id (numbers), so i should then get the names for each event from another table would that be possible in the same query?

thankyou

Got the answer,

when you try to ORDER by count(*), you should use AS like this:

Expand|Select|Wrap|Line Numbers
  1. SELECT count(*) AS what_you_count ORDER by 'what_you_count'
AS creates like an alias to the result array

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
