I have two tables user and user_role. Userid is primary filed into user table and foreign key in user_role table.
User_role has userid, roleid fileds.

There were some rows already into user table and corresponding to these userid fileld into user_role also.

User table example----
Userid loginid fname
1 a john
2 b karry

user_role example-----

user_id roleid
1 10
1 11
2 10
2 15

Later on I inserted some new rows into user tables ,
Now user table is like this----

user table---
Userid loginid fname
1 a john
2 b karry
3 america\c john
4 america\d karry

so i want that this new userid to be inserted into user_role table also with their already existing roleid.

Now the user_role table should like this---

user_id roleid
1 10
1 11
2 10
2 15
3 10
3 11
4 10
4 15

Please send me the query to work in sql server 2005.

You could use a subquery or CTE to get the roles per fname (including the user_id from the user_role table) and join that back to the user table. Based on that, insert the new values.

Please note that I decided against the option to provided the code snippet since I think you should give it a try based on the description. If you get stuck, post back your current query and what you're struggling with.

I'm afraid I don't quite follow exactly what you're getting stuck on. Is it how to get the keys back from the rows you just entered? There have been a number of posts and articles on this site discussing how to do that.

All questions have to be prefaced by Server version and 'according to MS Docs' or 'my own personal opinion based on how much detail I felt like digging into at the time.'

you need to decide that the new user is going to copy/inherit the roles of a specific user.
for example:

insert into user_role
select 
  3, --the userid of the new person who will receive/inherit the roles
   r.roleid 
from [role] r
where r.userid   IN(SELECT userid from [user] u WHERE fname = 'john')--he was userid 1 in your example
