I have Attendance table in that I have Columns: EmpCode,EmpName,1,2,3.......upt0 31(days).I am dumping attendance from excel sheet.

Ex:
EmpCode EmpName 1 2 3

Now what I am looking for is

loop columns from 1 to 31 and find no.of present days and no.of abscent days count.

o/p:
EmpCode EmpName No.ofpresentdays No.ofAbscentDays

1013 Ch.Krishna Mohan 2 1

how to acheive this in sqlserver??

What I have tried:

SELECT 'select '
+ QUOTENAME(c.name)
+ ',count(*) from [dbo].[EmpAttendance] group by ';
+ QUOTENAME(c.name)

FROM sys.columns c
WHERE c.object_id = OBJECT_ID(dbo.EmpAttendance;)

select [1],count(*) from [dbo].[EmpAttendance] where Empcode=1020 group by [1]

Please try this

C#

SELECT
   EmpCode,EmpName,[No.ofpresentdays],[No.ofAbscentDays]
FROM
   dbo.attendance T
   CROSS APPLY (
      SELECT Count(*)
      FROM (VALUES ([1]),	([2]),	([3]),	([4]),	([5]),	([6]),	([7]),	([8]),	([9]),	([10]),	([11]),	([12]),	([13]),	([14]),	([15]),	([16]),	([17]),	([18]),	([19]),	([20]),	([21]),	([22]),	([23]),	([24]),	([25]),	([26]),	([27]),	([28]),	([29]),	([30]),	([31])) C (Val)
      WHERE Val = 'P'
   ) A ([No.ofpresentdays])
    CROSS APPLY (
      SELECT Count(*)
     FROM (VALUES ([1]),	([2]),	([3]),	([4]),	([5]),	([6]),	([7]),	([8]),	([9]),	([10]),	([11]),	([12]),	([13]),	([14]),	([15]),	([16]),	([17]),	([18]),	([19]),	([20]),	([21]),	([22]),	([23]),	([24]),	([25]),	([26]),	([27]),	([28]),	([29]),	([30]),	([31])) C (Val)
      WHERE Val = 'A'
   ) P ([No.ofAbscentDays])
