Question

i have an situation where i have a following table.

    create table Bulk_Data
    (
    id int identity(1,1),
    UserName varchar(100) not null default 'default value ',
    iPartitionID int null
    )

also i have an Insert trigger on Bulk_Data.

create trigger dbo.Bulk_Data_IU on Bulk_Data 
AFTER INSERT  
AS Begin

    Merge Bulk_Data p1 
    using Bulk_Data p2 on p1.id = p2.id
    when matched then 
        update set p1.iPartitionID = right(p2.id,1);

end

condition in above table is like
i have 3 column which are not depended on any values.
1] id is identity auto increment column
2] UserName is set to be default values
3] iPartitionID is based on insert in Trigger.

so my question is how should i insert the records say suppose i do not required
to insert any values in #2 i.e. in column 2 so how should i fire the insert command on table.

because insert command is important for me as i have created Insert trigger.

when i run

insert Bulk_Data(UserName) values('Suraj Sheikh')

it works fine but what if i don’t want to insert any UserName.

is this possible ?

please help me out here.

You can use a computed column instead of a trigger that updates all rows for each insert.

create table Bulk_Data
    (
    id int identity(1,1),
    UserName varchar(100) not null default 'default value ',
    iPartitionID as id % 10 persisted
    )
