  create table yourquery (PageId	int, PageName	varchar(100), IsAccess int)
  
  insert into yourquery values(1,'Dashboard 1',1)
  ,(2,'Dashboard 2',0)
  ,(3,'Dashboard 3',1)
  ,(5,'Dashboard 4',1)
   
   
   
   --dynamic pivot with CASE
   Declare @sql nvarchar(max);
  Declare @ColumnHeaders VARCHAR(MAX) 
  SET @ColumnHeaders = STUFF( (SELECT DISTINCT ',' + 'Max(CASE WHEN rn=' + cast(rn as varchar(5)) 
  + ' THEN IsAccess else null end ) as ' + quotename('Dashboard'+Cast(rn as varchar(2)),'[')  + char(10)+char(13)
    FROM (Select * ,row_number() Over(Order by PageName) rn from yourquery) src
   FOR XML PATH(''), TYPE).value('.', 'varchar(max)'), 1, 1, '');
   --print @ColumnHeaders
   
   set @sql = N'SELECT ' + @ColumnHeaders + '  FROM   (Select * ,row_number() Over(Order by PageName) rn from yourquery) src  ';
  --print @sql
  exec(@sql);
  
  drop table yourquery
