I have the below
Name Date
A 2011-01-01 01:00:00.000
A 2011-02-01 02:00:00.000
A 2011-03-01 03:00:00.000
B 2011-04-01 04:00:00.000
A 2011-05-01 07:00:00.000
The desired output being
Name StartDate EndDate
-------------------------------------------------------------------
A 2011-01-01 01:00:00.000 2011-04-01 04:00:00.000
B 2011-04-01 04:00:00.000 2011-05-01 07:00:00.000
A 2011-05-01 07:00:00.000 NULL
How to achieve the same using TSQL in Set based approach
DDL is as under
DECLARE @t TABLE(PersonName VARCHAR(32), [Date] DATETIME)
INSERT INTO @t VALUES('A', '2011-01-01 01:00:00')
INSERT INTO @t VALUES('A', '2011-01-02 02:00:00')
INSERT INTO @t VALUES('A', '2011-01-03 03:00:00')
INSERT INTO @t VALUES('B', '2011-01-04 04:00:00')
INSERT INTO @t VALUES('A', '2011-01-05 07:00:00')
Select * from @t
