sql - Sqlite: Get Modal/Mode from two related columns -


this extract table games:

id  wuser       buser 1   ddyer       bdot 2   ddyer       ronaldinho 3   bluedog     ronaldinho 4   ronaldinho  bluedog 5   bluedog     ronaldinho 6   ddyer       bobc 7   bobc        ddyer

the table database website boardspace.net in people play board games. in database wuser , buser white , black players, , id game played. want know players played most. white players:

 select wuser, count(wuser)   game   group wuser   order count(wuser) desc;

result is:

wuser    count(wuser) dumbot   75926 guest    22541 image13  1594 drraven  1460 eucalyx  1147 loizz    963

then have same black players:

 select buser, count(buser)   game   group buser   order count(buser) desc;  buser    count(buser) dumbot   59489 guest    29324 eucalyx  1007 image13  756 drraven  746 loizz    715 alexis   660

i can sum manually did below, how result single sql statement: 

user     count(as both buser , wuser) dumbot   135412 guest    51865 image13  2350 drraven  2206

i want know total number of games played each player, not interested whether play white or black.

as got large number of rows per user better count before union , add aggregate step:

select usr, sum(cnt)  (    select wuser usr, count(*) cnt    game     group wuser     union     select buser, count(*)     game     group buser  ) dt  group usr  order sum(cnt) desc;

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
