jump to a particular page in pagination

On one page in my application there is a list of all the merchants that
are in the system and with each merchant there is a link which takes the
user to a page where the details are listed of all the merchants using
pagination. I can show all the merchants using pagination. But the
problem is that how do I know which page I have to show when the link is
clicked. For ex. if there are 100 merchants and I list then and user
clicks on 'DEF' , then how do I know that 'DEF' will be on page 5 and
show page 5 directly and from there user and use next,first, etc.
buttons to go through the rest.

You seem to be asking two contradictory questions.

Either you have the situation of so many users per page, say 10.
In which case the links are something like

    Page 1, items 00 - 09 search condition: offset = 0, count = 10
    Page 2, items 10 - 19 search condition: offset = 10, count = 10
    Page 3, items 20 - 29 search condition: offset = 20, count = 10
    ...

Of course you could have overlap

The other is that you are presenting an alphabetic interface, like a
telephone number insert in your DayTimer(c) pocket book

   Page 1, ABC search condition: name begins with A or B or C
   Page 2 DEF search condition: name begins with D or E or F
   ....

Of course with this arrangement you may, just like in your DayTimer(c), have
pages with no entries.

I suppose you could paginate the "ABC"s etc.,

Personally I believe in K.I.S.S. Simple pagination is good, but you also
want a search box. A 'search for names beginning with ..." type search is
good. Think about what the voice-menu systems on many corporate IVR s
offer: "Corporate directory: key in the first few letters of the name of the
person you wish to speak to ..."

If its simple for the user its probably going to be simple for you as well.

What I want is something like this:

Suppose I have a drop-down with the names of all the merchants that are
in system and I select one say 'John Doe'. then the screen should be
displayed which has the details of 'John Doe' in a html table row. And
that table is a page in a pagination_by_sql. This means that it is the
page which has 'john doe' alongwith other merchants and user can use
'next', previous buttons etc to see other merchants. Kind of table of
contents in a book gives me page number of a topic and from there I can
turn pages and read any part of the book. Table of contents just gave me
a landing page to land and then I can move around. Something like this I
want.

What you're describing is essentially a "starting at" mechanism.

But make up your mind. You've now described THREE completely different user
interfaces. All are valid, all are intelligible to the user. Each by itself.

Pick one and stick with it.

Stop jumping around in your design or adding too many features.
You'll only confuse the user, not impress him with your technical skills.

There's a term for this" "Creeping feaureitis".
Its a pernicious disease and often fatal to the product unless cured by
amputation or the application of marketing dollars on a scale only possible
by the likes of Microsoft or IBM. (e.g Microsoft Word)
