Dear,
I have a view that is comprised of multiple tables containing only today's data. I used only select statement in that view. Now I want to write a trigger on that view that when a new row is inserted, it will insert a row into another table.
What can I do for that? Please suggest me in your earlier time.
Regards,
Akbar

What exactly is your problem? According to
BOL
"A view can be referenced only by an INSTEAD OF trigger."

That likely will not help the situation. There is unique value added to the system when an instead trigger is placed on a view that joins multiple tables. Namely that we can support inserts into that view where before, without the instead trigger, we could not.
From
http://msdn.microsoft.com/en-us/library/ms175521(v=sql.105).aspx
The primary advantage of INSTEAD OF triggers is that they enable views that would not be updatable to support updates. A view based on multiple base tables must use an INSTEAD OF trigger to support inserts, updates, and deletes that reference data in more than one table.
