Displaying counts for all Dates in to multiple columns - Advance SQL

Question 1

Here is some code for MS-SQL that will give the results you are looking for. It creates a dynamics sSQL script and executes this to get the results. If this does not solve your problem 100% I hope it at least points you in the correct direction.

CREATE TABLE  #Data (Dept VARCHAR(20),TicketCode VARCHAR(100), AsOfDate DATETIME, FixedBy VARCHAR(10), FixedDate DATETIME)

DECLARE @StartDate      AS  DATETIME
DECLARE @EndDate        AS  DATETIME
DECLARE @ProcessDate    AS  DATETIME
DECLARE @sSQL           AS  VARCHAR(MAX)
DECLARE @dtString       AS  VARCHAR(100)

SET @StartDate  = '2014-03-19'
SET @EndDate    = '2014-03-21'

INSERT INTO #Data (Dept, TicketCode, AsOfDate, FixedBy, FixedDate) VALUES('merlin ',' ACE4E957-62C9-4447-A39E-AAA6928C7DD3 ',' 2014-03-04 ',' Mark   ',' 2014-03-05 ')

SET @ProcessDate = @StartDate 

SET @sSQL = 'SELECT Dept,FixedBy '

/*Create the Dynamics SQL for the Columns*/
WHILE @ProcessDate < @EndDate
    BEGIN
        SET @dtString = CAST(YEAR(@ProcessDate) AS CHAR(4)) + '_'  +  CAST(MONTH(@ProcessDate) AS VARCHAR(2)) + '_' + CAST(DAY(@ProcessDate) AS VARCHAR(2))
        SET @sSQL = @sSQL + ',
            SUM(CASE WHEN FixedDate = ''' + CAST(@ProcessDate AS CHAR(20)) +  ''' THEN  1 ELSE 0 END) AS dt_' + @dtString
        SET @ProcessDate = @ProcessDate + 1
    END 
SET
    @sSQL = @sSQL +  ' FROM #Data GROUP BY Dept,FixedBy ORDER BY Dept,FixedBy '

SELECT  @sSQL /*To see what will execute*/ 

EXECUTE (@sSQL)  /*Run the Query to return results*/ 

DROP TABLE #Data  /*Remove table*/

Question 2

It is relatively easy to solve with dynamic pivot. However, your results don't match your data -- there are only two rows in sample data for range between '2014-03-05' and '2014-03-08'.

Here's the code:

declare @start_date as date,
@end_date as date;

select @start_date = '2014-03-05', @end_date = '2014-03-08';

declare @collist nvarchar(max)
set @collist = stuff((select distinct ',' + quotename(convert(varchar(8), FixedDate, 112)) 
    from #t -- your table here
    where FixedDate between @start_date and @end_date
    for xml path(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')

declare @q nvarchar(max)
set @q = '
select Dept, FixedBy, ' + @collist + ' 
from (
    select Dept, FixedBy, FixedDate, TicketCode
        from (
        select *
        from #t -- your table here
    where FixedDate between ''' + convert(varchar(8),@start_date,112) + ''' and ''' + convert(varchar(8),@end_date,112) + '''
    ) as x
) as source
pivot (
    count(TicketCode)
    for FixedDate in (' + @collist + ')
) as pvt
'
exec (@q)

Result (using the insert script by @Richard, thx):

Dept                 FixedBy    20140305    20140306
