if you need this in sql server, you can use row_number for mysql, there is no equivalent of this, but you have a work around:

SQL

SQL Server:
USE AdventureWorks2008R2;
GO
WITH OrderedOrders AS
(
    SELECT SalesOrderID, OrderDate,
    ROW_NUMBER() OVER (ORDER BY OrderDate) AS 'RowNumber'
    FROM Sales.SalesOrderHeader
)
SELECT *
FROM OrderedOrders
WHERE RowNumber BETWEEN 50 AND 60;

MySQL:
SELECT @i:=@i+1 AS iterator, t.* FROM tablename t,(SELECT @i:=0) foo
