Question

I’ve got 2 queries I’d like to merge into 1 result set without using union.

Query 1

select  datepart(yy,dateclosed)as 'Year',
    datepart(mm,dateclosed) as 'Month',
    count(*)as 'Total' 
from bug 
where projectid = 44 
and ifclosed = 1
and isnull(createdbyperson,1) <> '-1111111110'
and datepart(yy,dateclosed) > '2000'
group by datepart(yy,dateclosed), datepart(mm,dateclosed)
order by 1,2

Query 2

select  datepart(yy,dateclosed)as 'Year',
    datepart(mm,dateclosed) as 'Month',
    count(*)as 'SameDay' 
from bug 
where   projectid = 44 
        and ifclosed = 1
        and isnull(createdbyperson,1) <> '-1111111110'
        and datepart(yy,dateclosed) > '2000' 
        and CONVERT(VARCHAR(10), dateclosed, 101) = CONVERT(VARCHAR(10), datecreated, 101) 
group by datepart(yy,dateclosed),datepart(mm,dateclosed)
order by 1,2

Id like it to return the values as Year,Month,SameDay,Total. How do I achieve this? Union doesn’t do what I want it to do. Do I have to do a join and a table alias? Subquery?

Thanks in advance.

Answer 1

OK…what about this one:

select a.Year, a.Month, b.SameDay, a.Total
from
(
select  datepart(yy,dateclosed)as 'Year',
    datepart(mm,dateclosed) as 'Month',
    count(*)as 'Total' 
from bug 
where projectid = 44 
and ifclosed = 1
and isnull(createdbyperson,1) <> '-1111111110'
and datepart(yy,dateclosed) > '2000'
group by datepart(yy,dateclosed), datepart(mm,dateclosed)
) a
inner join
(
select  datepart(yy,dateclosed)as 'Year',
    datepart(mm,dateclosed) as 'Month',
    count(*)as 'SameDay' 
from bug 
where   projectid = 44 
        and ifclosed = 1
        and isnull(createdbyperson,1) <> '-1111111110'
        and datepart(yy,dateclosed) > '2000' 
        and CONVERT(VARCHAR(10), dateclosed, 101) = CONVERT(VARCHAR(10), datecreated, 101) 
group by datepart(yy,dateclosed),datepart(mm,dateclosed)
) b
on a.Year = b.Year AND a.Month = b.Month
order by 1,2
