Question

I have many database entries, each containing a value.

I want to show some statistics regarding those values, so I should be able to say:

• how many entries (rows) have the value between 0 and 5,
• how many entries (rows) have the value between 6 and 10,
• how many entries (rows) have the value between 11 and 20,
• how many entries (rows) have the value more then 20.

(the values above where given only as an example)

Let’s say I’ll have like 6-7 intervals that I want to group the values by. Can I do this in a single MySQL query? If yes, how can I acces the grouped values using photoshop PHP aftewards?

Thanks!

EDIT:
Seems like the query is actually harder. I have 2 columns (val1 and val2). I want the query to count how many items have val1/val2 (val1 divided by val2) between an interval…

Answer 1

SELECT 
   SUM(col BETWEEN 0 AND 5) AS 0_to_5,
   SUM(col BETWEEN 6 AND 10) AS 6_to_10,

etc. etc.

re: your edit:

  SELECT 
   SUM(val1/val2 BETWEEN 0 AND 5) AS 0_to_5,
   SUM(val1/val2 BETWEEN 6 AND 10) AS 6_to_10,
