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.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
