Please give an SQL trigger which set user defined value as default.
e.g.
create table Student
(srNo int IDENTITY(1,1) not null,
RollNo int not null default <srno> -- This column will contains <srno> as default if user doesn't provide
StudentName varchar(50) not null)

You don't need a trigger for a default. What exactly is your question?

create table Student
(srNo int IDENTITY(1,1) not null,
RollNo int not null default as srNo-- This column will contains as default if user doesn't provide any. Here I need 'srNo' as default for 'RollNo' column.
StudentName varchar(50) not null)

Oh, thank you for clearing it up by repeating yourself verbatim.

interview question or homework?

i *think* what you're after is an Insert Trigger[^], because that RollNo is not an identity column, and presumably is different per student (tho' that's me reaching, because your question is poor)

Examples of use[^]
