I Need to create a pivot table in which first column contain the employee name and next column header contain the all the date of a month and last column will show how many present days

can you help me

SQL

ALTER procedure [dbo].[EmpAttandance] @iMon int,@iyear int
as
begin
-- Getting all distinct dates into a temporary table #Dates
SELECT DISTINCT ADate INTO #Dates
FROM AttandanceTran where DATEPART(MM,ADate) =@iMon and DATEPART(YYYY,ADate)=@iyear
ORDER BY ADate


-- The number of days will be dynamic. So building
-- a comma seperated value string from the dates in #Dates
DECLARE @cols NVARCHAR(4000)
SELECT  @cols = COALESCE(@cols + ',[' + CONVERT(varchar, Adate, 106)
				+ ']','[' + CONVERT(varchar, Adate, 106) + ']')
FROM    #Dates
ORDER BY Adate

-- Building the query with dynamic dates
DECLARE @qry NVARCHAR(4000)
SET @qry =
'SELECT * FROM
(SELECT Empcode,Name,Type,Adate,count(type) over(PARTITION BY empcode) AS Tot
FROM AttandanceTran,Empmast where Empmast.ECode=AttandanceTran.Ecode 
 and DATEPART(MM,ADate)=' + CAST(@imon as varchar(10)) + '
 and DATEPART(YYYY,ADate)=' + CAST(@iyear as varchar(10)) + ' )emp
PIVOT (Max(Type) FOR ADate IN (' + @cols + '))  AS Type'


-- Executing the query
EXEC(@qry)


-- Dropping temporary tables
DROP TABLE #Dates

Main note is: Replace relationship based on WHERE clause with JOIN statement
Replace:

SQL

SELECT Empcode,Name,Type,Adate,count(type) over(PARTITION BY empcode) AS Tot
FROM AttandanceTran,Empmast where Empmast.ECode=AttandanceTran.Ecode
 and DATEPART(MM,ADate)=' + CAST(@imon as varchar(10)) + '
 and DATEPART(YYYY,ADate)=' + CAST(@iyear as varchar(10))

with:

SQL

SELECT em.Empcode, em.Name, em.Type, at.Adate, COUNT(at.type) AS Tot
FROM AttandanceTran AS at INNER JOIN Empmast AS em ON at.ECode=em.ECode
WHERE DATEPART(MM,ADate)=@iMon AND DATEPART(YYYY,ADate)=@iyear

Do you see the difference? I'm using JOIN[^] statement to create relationship between both tables. Have a look here: Visual Representation of SQL Joins[^]
