Here it is

SQL

create table #tempMonths (monthNr int)
insert into #tempMonths (monthNr) values (1) 
insert into #tempMonths (monthNr) values (2)
insert into #tempMonths (monthNr) values (3)
insert into #tempMonths (monthNr) values (4)
insert into #tempMonths (monthNr) values (5)
insert into #tempMonths (monthNr) values (6)
insert into #tempMonths (monthNr) values (7)
insert into #tempMonths (monthNr) values (8)
insert into #tempMonths (monthNr) values (9)
insert into #tempMonths (monthNr) values (10)
insert into #tempMonths (monthNr) values (11)
insert into #tempMonths (monthNr) values (12)

SELECT  isnull( YEAR(RequestedDate) ,YEAR(getdate()))  as Years,
isnull( Month(RequestedDate),temp.monthNr) as MonthInNumbers,temp.monthNr,
Count(Month(RequestedDate)) as MonthCount
 
FROM tblMYTABLE
right join #tempMonths temp on temp.monthNr =  Month(RequestedDate)
GROUP BY YEAR(RequestedDate),Month(RequestedDate),temp.monthNr

drop table #tempMonths

Why not use @TableVar instead of a temptable#, I wonder if I have asked you this question before!

It makes no difference to the solution, Blue Boy has given you the definitive solution.

A temp table creates a table object in the temp database and writes the data to the hard drive. A table variable does this in memory, there are some benefits to both. A temp table can have indexes applied and a global temp table can be shared between procedures.

I default to table vars, BB probably defaults to temp tables, I was wondering if there was a reason.

Another option is the USE of Decode function that will also give u the correct result with out using the temp table or variable, if u can share the data of yr mytable then will try to give u the sql query.

Hope this will work

SQL

select years, month, sum(MonthCount) from
 (
 SELECT  to_char(trunc(RequestedDate, 'Year'), 'YYYY') as Years, to_char(trunc(RequestedDate, 'Month'), 'MON') as Month, count(to_char(trunc(RequestedDate, 'Month'), 'MON')) as MonthCount
 FROM MYTABLE
 group by to_char(trunc(RequestedDate, 'Year'), 'YYYY'), to_char(trunc(RequestedDate, 'Month'), 'MON')
  union
 select '2012' as years, 'JAN' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'FEB' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'MAR' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'APR' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'MAY' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'JUN' as Month, 0 as MonthCount from dual
 union

Hey i just used the trunc method for oracle, u can replace to yr old year and month method to get the result, but the concept is that we will use the union clause to get the data for those month for which we dont have the data than we will do a union with yr old query then on the top of that put a sum for monthcount with group by month and year.

so yr query will be

SQL

select years, month, sum(MonthCount) from
 (
 SELECT  YEAR(RequestedDate) as Years, Month(RequestedDate) as MonthInNumbers,Count(Month(RequestedDate))
 FROM MYTABLE
 group by YEAR(RequestedDate),Month(RequestedDate)
  union
 select '2012' as years, 'JAN' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'FEB' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'MAR' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'APR' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'MAY' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'JUN' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'JULY' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'AUG' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'SEPT' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'OCT' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'NOV' as Month, 0 as MonthCount from dual
 union
 select '2012' as years, 'DEC' as Month, 0 as MonthCount from dual
 ) group by years, month
