database - getting count of users in periods of times in MySQL -


I want to calculate my users from time to time in MySQL I have written this question (I know that this is correct But this query only gives me the number of registered users from time to time. 

  SELECT DATE_FORMAT (reg_date, '% Y-% V') in the form of 'Week', by counting (*) as 'user' group by wik   
 
 
 
 Your question - as of now - is not very specific, ...  
 Since you are using a field called reg_date, which you group, it will suggest that you get the countdown date registration date, so you have a separate column for your  'wik'  Will have to take.  
 Another possibility may be that you have to use a completely different table, where "user actions" (or whatever you want) - can be stored - instead of users' data is.
