Question

Is there a query where I could match if field cmd has been sent more then 3 times with the same content in the last 15 minutes ?

I currently have this:

SELECT COUNT(*) 
FROM `log` 
WHERE gid = @gid 
AND ts_register BETWEEN DATE_SUB(NOW() , INTERVAL 15 MINUTE) AND NOW()

Which will gather me all the messages sent in the last 15 minutes by the global id.

Is there a way to take the field cmd into consideration and list if the gid has sent a repeated cmd more then 3 times within the last 15 minutes ?

for example:

gid 1 cmd testing repeatable cmd
gid 1 cmd testing repeatable cmd
gid 1 cmd testing repeatable cmd
gid 1 cmd different cmd

So it would give me the count of 3.

You want to do this:

SELECT cmd, COUNT(*) Qty
FROM `log` 
WHERE gid = @gid 
AND ts_register BETWEEN DATE_SUB(NOW() , INTERVAL 15 MINUTE) AND NOW()
GROUP BY cmd

Given your data, that would return:

Cmd                                  Qty
---                                  ---
gid 1 cmd testing repeatable cmd     3
gid 1 cmd different cmd              1

Update

Using @Gidon’s suggestion (Upvoted you, man!), you can add a HAVING clause to display only the ones with more than 3:

SELECT cmd, COUNT(*) Qty
FROM `log` 
WHERE gid = @gid 
AND ts_register BETWEEN DATE_SUB(NOW() , INTERVAL 15 MINUTE) AND NOW()
GROUP BY cmd
HAVING COUNT(*) > 3
