Try this. If you have post the sample data.

SQL

declare @m varchar(2), @y varchar(4)
set @m = '08'
set @y=2012

DECLARE @date DATETIME
SELECT @date = convert(datetime, @m  + '-01' + '-' + @y)
--select @date
SELECT @date=DATEADD(d, -1, DATEADD(m, DATEDIFF(m, 0, @date) + 1, 0))

declare @Empmaster table (
Emp_Joinindate datetime,Emp_leavingdate datetime,Emp_Status varchar(2)
)

insert @Empmaster values ('04-01-2012','05-01-2012','1')
insert @Empmaster values ('04-01-2012',NULL,'1')
insert @Empmaster values ('05-01-2012',null,'1')
insert @Empmaster values ('05-01-2012','07-01-2012','1')
insert @Empmaster values ('06-01-2012',null,'1')
insert @Empmaster values ('07-01-2012',null,'1')

//Active emp
select * from @Empmaster
where Emp_Joinindate <= @date and (ISNULL(Emp_leavingdate,'12-31-9999')) >= @date

// Emp left
select * from @Empmaster
where Emp_Joinindate <= @date and (ISNULL(Emp_leavingdate,'12-31-9999')) <= @date

You can try this one too

SQL

SELECT SUM(CASE WHEN Emp_Status = 1 AND datepart(MONTH,[Emp_Joinindate]) = DATEPART(Month,GETDATE()) AND datepart(YEAR,[Emp_Joinindate]) = DATEPART(YEAR,GETDATE())
AND Emp_LeftDate IS NULL
THEN 1 ELSE 0 END) as WorkingEmp ,
SUM(CASE WHEN Emp_Status = 0 AND datepart(MONTH,[Emp_Joinindate]) = DATEPART(Month,GETDATE()) AND datepart(YEAR,[Emp_Joinindate]) = DATEPART(YEAR,GETDATE())
AND Emp_LeftDate IS NOT NULL
THEN 1 ELSE 0 END) as LeftEmployee ,
from EmployeeMaster

For Employees Who Are Working I am assuming That Their Leaving Date Is Null Obviously

Select * From Empmaster Where Emp_LeavindDate Is Null
And DatePart(mm,EmpJoinInDate) = 'MONTH PARAMETER HERE In Numeric'
And DatePart(yy,EmpJoinInDate) = 'YEAR MONTH PARAMETER HERE In Numeric'

For Employees Who Have Left I am assuming That Their Leaving Date Is Not Null Obviously

Select * From Empmaster Where Emp_LeavindDate Is Not Null
And DatePart(mm,EmpLeavingDate) = 'MONTH PARAMETER HERE In Numeric'
And DatePart(yy,EmpLeavingDate) = 'YEAR MONTH PARAMETER HERE In Numeric'

Count the no of Employee Presently working (Active emp) and count of Employee Presently not working (InActive emp) based on Month of the Year
