JUST BASED ON YOUR ID FIELD WRITE QUERY LIKE THIS YOU WILL GET ONLY LAST THREE RECORDS FROM THOUSANDS OF RECORDS.
SUPPOSE U HAVE A TABLE EMPLOYEE WITH FIELDS EMP_ID ,EMP_NAME,EMP_AGE,EMP_DESG,EMP_SAL ETC..............

HAVING EMP_ID INT DATA-TYPE,
FOR GETTING ONLY LAST THREE RECORDS JUST U HAVE TO WRITE QUERY LIKE THIS,


SELECT TOP 3 * FROM EMPLOYEE ORDER BY EMP_ID DESC

OR IF U DON'T HAVE FIELD LIKE MY SUGGESTED TABLE U CAN JUST REPLACE THE FIELD NAME EMP_ID WITH YOUR FIELD HAVING SERAIL NO OR LIKE THAT WHICH HAVE INT , NUMERIC OR DECIMAL DATA-TYPE
