Вы можете сделать это, используя немного DATEDIFF и PIVOT. Вот так ...
select name, max(DAY_1) as DAY_1, max(DAY_2) as DAY_2, max(DAY_3) as DAY_3, max(DAY_4) as DAY_4, max(DAY_5) as DAY_5 from (
SELECT s.value_Date, name, end_datetime,
'DAY_' + cast( DATEDIFF(DAY, dates.value_date, today.value_date) as varchar) as day
FROM schema1.VW_SKY_BATCH_STATUS S
CROSS JOIN (select top 1 VALUE_DATE from schema2.BUSINESS_DATE where CALENDAR = 'london' order by VALUE_DATE desc) as today
JOIN (select top 6 VALUE_DATE from schema2.BUSINESS_DATE where CALENDAR = 'london' order by VALUE_DATE desc) dates on dates.VALUE_DATE = s.VALUE_DATE
JOIN Reports.REPORT_DESCRIPTION rd on rd.ID = s.PROFILE_ID)
AS SourceTable
PIVOT (MAX(end_datetime) FOR day IN (DAY_1, DAY_2, DAY_3, DAY_4, DAY_5)) AS pt
GROUP BY name
