如何查看 SQL 表中的最近记录？

Question

I have one table called "Mydata" with date,name,address columns this table is having more than 5000 records now i dont want to view all 5000 records I just want to view recently added 100 records, how can i do that I tried with select top 100 * from Mydata But which is not giving me recently added records

Answer 1

For TOP 100 * to work as you desire, you need to specify the order in which to return the records. Use the example below and replace [YourField] with whatever column determines the order in which the records were inserted.

SELECT TOP 100 *
FROM       Mydata
ORDER BY   [YourField] DESC --Could be the date added column, or the primary key.

Answer 2

The ordering of the data is not guaranteed. Well that's not entirely correct as you can cluster there data by a field. However unless put the insertion data an time on the row in a field, you can't query by that.

So add a column (say called insdate) to your table what puts the current date and time into the row when you insert it. Then query by date time ordering

select top 100 * from mydata order by insdate desc

Like james hill says, you can use any column to indicate the ordering if the value is unique and changes in the same way.
