all sql script can think group by. it's works group date.

here's script:

select * evaluation group year,month(datetime) asc

how count unique value of each evaluation.

create data structure , fill test data:

create table evaluation (   evaldate date not null,   grade1 int(11) not null,   grade2 int(11) not null,   grade3 int(11) not null,   grade4 int(11) not null,   grade5 int(11) not null,   primary key (evaldate) );  insert evaluation values('2015-07-14', 1, 2, 3, 4, 5); insert evaluation values('2015-07-15', 2, 2, 2, 2, 2); insert evaluation values('2015-08-12', 5, 4, 3, 2, 1); insert evaluation values('2015-08-13', 1, 1, 1, 1, 1);

perform query want do:

select year(evaldate)      , month(evaldate)      , sum(grade1)      , sum(grade2)      , sum(grade3)      , sum(grade4)      , sum(grade5)    evaluation   group      year(evaldate)      , month(evaldate);

returns:

year(evaldate) month(evaldate) sum(grade1) sum(grade2) sum(grade3) sum(grade4) sum(grade5) 2015           7               3           4           5           6           7 2015           8               6           5           4           3           2
