Hi Gani,

We can get the desired result set using the CTEs to get the filtered result and STUFF function on it to concatenate the Employee names.

Note : Your test data contains invalid Date (ie2012-5-2012..)

Go through the following code.

--Creating Temp table

SQL

CREATE TABLE [dbo].[Temp](
	[EmpId] [int] NULL,
	[EmpName] [varchar](30) NULL,
	[StartTime] [datetime] NULL
)

-- Insert Data into Temp table

SQL

INSERT INTO [Temp]([EmpId],[EmpName],[StartTime])VALUES
 (101,'Abdul','2012-05-01 08:40:30.000'),
 (101,'Abdul','2012-05-01 09:40:30.000'),
 (101,'Abdul','2012-05-01 12:20:30.000'),
 (102,'Raju','2012-05-01 08:15:30.000'),
 (102,'Raju','2012-05-01 12:40:30.000'),
 (102,'Raju','2012-05-01 16:20:30.000'),
 (103,'Albert','2012-05-01 08:40:30.000'),
 (103,'Albert','2012-05-01 10:40:30.000'),
 (103,'Albert','2012-05-01 12:20:30.000'),
 (103,'Albert','2012-05-01 14:40:30.000'),
 (103,'Albert','2012-05-01 15:40:30.000'),
 (103,'Albert','2012-05-01 17:10:30.000'),
 (103,'Albert','2012-05-01 17:15:30.000'),
 (104,'Raghu','2012-05-01 08:00:30.000'),
 (104,'Raghu','2012-05-01 09:40:30.000'),
 (104,'Raghu','2012-05-01 12:20:30.000'),
 (102,'Johnson','2012-05-01 08:00:30.000'),
 (102,'Johnson','2012-05-01 12:40:30.000'),
 (102,'Johnson','2012-05-01 16:20:30.000')
