FROM MyTable
ORDER BY Id DESC

I\'ve a table wi

Answer 1

MS doesn't support LIMIT in t-sql. Most of the times i just get MAX(ID) and then subtract.

select * from ORDERS where ID >(select MAX(ID)-10 from ORDERS)

This will return less than 10 records when ID is not sequential.

Answer 2

DECLARE @MYVAR  NVARCHAR(100)
DECLARE @step  int
SET @step = 0;


DECLARE MYTESTCURSOR CURSOR
DYNAMIC 
FOR
SELECT col FROM [dbo].[table]
OPEN MYTESTCURSOR
FETCH LAST FROM MYTESTCURSOR INTO @MYVAR
print @MYVAR;


WHILE @step < 10
BEGIN   
    FETCH PRIOR FROM MYTESTCURSOR INTO @MYVAR
        print @MYVAR;
        SET @step = @step + 1;
END   
CLOSE MYTESTCURSOR
DEALLOCATE MYTESTCURSOR

Answer 3

You can do it by using the ROW NUMBER BY PARTITION Feature also. A great example can be found here:

I am using the Orders table of the Northwind database... Now let us retrieve the Last 5 orders placed by Employee 5:

SELECT ORDERID, CUSTOMERID, OrderDate
FROM
(
    SELECT ROW_NUMBER() OVER (PARTITION BY EmployeeID ORDER BY OrderDate DESC) AS OrderedDate,*
    FROM Orders
) as ordlist

WHERE ordlist.EmployeeID = 5
AND ordlist.OrderedDate <= 5

Answer 4

Maybe a little late, but here is a simple select that solve your question.

SELECT * FROM "TABLE" T ORDER BY "T.ID_TABLE" DESC LIMIT 5;

Answer 5

In a very general way and to support SQL server here is

SELECT TOP(N) *
FROM tbl_name
ORDER BY tbl_id DESC

and for the performance, it is not bad (less than one second for more than 10,000 records On Server machine)

Answer 6

To display last 3 rows without using order by:

select * from Lms_Books_Details where Book_Code not in 
 (select top((select COUNT(*) from Lms_Books_Details ) -3 ) book_code from Lms_Books_Details)
