You'll need some data in the table to record when the data was inserted and if it was previously "read". When you retrieve the records from the table, you can either retrieve the records from the last date/time that was "read", tracked by your code elsewhere, or you can retrieve records that were "read" before with the flag and just retrieve records that have not been "read". You'll have to have some mechanism in your site to let the user mark thee records "read" so you don't retrieve them again.

Hi,

If you want to return recently inserted records there should be a date filter, I assume that you are looking recent insert records for past 1week.

Refer below sample query for the same

SQL

Declare @tab table
(
    val int,
	insertdate datetime
)

insert into @tab
values(100,'2015-11-09 12:23:30.377'),(101,'2015-11-10 12:23:30.377'),(102,'2015-11-11 12:23:30.377'),
(104,'2015-11-12 12:23:30.377'),(105,'2015-11-13 12:23:30.377'),(106,'2015-11-14 12:23:30.377'),
(107,'2015-11-15 12:23:30.377'),(108,'2015-11-16 12:23:30.377')

select * from @tab
where CONVERT(date, insertdate) >=CONVERT(date, GETDATE()-7)

Solution 1

Select *top 3 from your_table orderby ID DESC
This query will fetch last 3 records you have inserted

And if you don't know how many records were inserted your code falls on its face.
