as 
--DECLARE @startdate int 
--DECLARE @enddate int 
--declare @strdays NVARCHAR(4000) declare @cols NVARCHAR(4000) DECLARE @qry NVARCHAR(4000) DECLARE @where VARCHAR(20) begin 

    --select @startdate from att --union ALL --select @startdate 
+ 1 from att  --where @startdate < @enddate into #Dates ; 

SELECT DISTINCT Date1 INTO #Dates FROM att where Date1 between @startdate and @enddate ORDER BY Date1; 

SELECT @cols = COALESCE(@cols + ', ['+ convert(varchar(50),DATEPART(d,Date1),106) + ']', '['+ convert(varchar(50),DATEPART(d,Date1),106) + ']') from #Dates ; 


SET @qry = 

'SELECT * FROM (SELECT name, status,class, DATEPART(d,Date1) Date1 FROM att) tbldate PIVOT (MAX(status) FOR Date1 IN (' + @cols + ')) AS stat'; 



Execute(@qry) 

-- Dropping temporary tables DROP TABLE #Dates; 

end GetAttn1 '2017-08-10','2017-08-30','LKG'

改變你的@qry到

SET @qry = 

'SELECT * FROM (SELECT name, status,class, DATEPART(d,Date1) Date1 FROM att WHERE class = @class1) tbldate PIVOT (MAX(status) FOR Date1 IN (' + @cols + ')) AS stat';
