This is a program to divide the records in a table between more than one page
depending on from which record onwards you want to display and how many records
per page you want to display. This program was written by Rajendra k. Shrestha My
email address rajensama@yahoo.com You are free to use ,change and distribute the
script to anybody any where and I do not have any responsibility if it does not
work but if you have any problem with script you may contact me in my email address

To use this file
1. create a database with username and password
I have used user "sa77bk" and password= "password",
2. create a database called "sa77bk"
3. create table "loginlog" which I have used in this script
To create a table use the script given below

create a table called loginlog for you use

create table loginlog(
username varchar(10) not null ,
logintime datetime);

insert into loginlog values('rajendra','1996-10-10 12:10:55');
insert into loginlog values('rajendra','1996-10-10 13:10:55');
insert into loginlog values('rajendra','1996-10-10 13:10:56');
insert into loginlog values('rajendra','1996-10-10 13:10:54');
