mysql - SQL Statement - Create a Report with three totals -


having little trouble creating query in mysql. think i'm missing obvious.

i have users table, has column called device (android, ios, windows 3 possible values). create report tells me how many users registered each day (so group date) each device (so total in each column).

i able make query tells me how many users registered total first column, couldn't sub-queries working in next few columns.

right working query tried this:

select count(u.userid) 'total users', date(u.datecreated) 'day' users group date(u.datecreated) order u.datecreated desc

this produces nice aggregated report me shows # of users created each day (the total 1 column, date total second column)

so expanding on working query above, tried making subquery keeps producing '1' result new column.

select count(distinct u.userid) 'total users',  (select count(u1.userid) users u1 u1.datecreated = u1.datecreated , u.device = 'android' group u1.datecreated) 'android users', date(u.datecreated) 'day' users u group date(u.datecreated) order u.datecreated desc

how inner query produce total number of android users day?

for each type of device can count subtotal using case statement.

try this:

select     count(u.userid) 'total users',     sum(case when device = 'android' 1 end) android,     sum(case when device = 'ios' 1 end) ios,     sum(case when device = 'windows' 1 end) windows,     date(u.datecreated) 'day' users group date(u.datecreated) order date(u.datecreated) desc

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
