Question

I have a table that has a column with a default value:

create table t (
    value varchar(50) default (\'something\')
)

I\'m using a stored

Answer 1

The best option by far is to create an INSTEAD OF INSERT trigger for your table, removing the default values from your table, and moving them into the trigger.

This will look like the following:

create trigger dbo.OnInsertIntoT
ON TablenameT
INSTEAD OF INSERT
AS
insert into TablenameT
select
   IsNull(column1 ,)
  ,IsNull(column2 ,)
  ...
from inserted

This makes it work NO MATTER what code tries to insert NULLs into your table, avoids stored procedures, is completely transparent, and you only need to maintain your default values in one place, namely this trigger.
