Question

I have a requirement to insert the literal value ‘NULL’ into a nvarchar column as a default value. But when I insert records the default is going as db NULL instead of the literal ‘NULL’. Can someone tell me where I am going wrong?

Answer 1

So you want the actual string of “NULL” to be inserted? Try something like this:

create table NullTable
(
    nvarchar(100) not null default 'NULL',
    .... -- your other fields
)

EDIT: Here is a full solution

create table InsertNull
(
    Nullfield nvarchar(100) not null default 'NULL',
    someint int not null
)
go

insert into insertnull(someint)
select 20

select *
from InsertNull
