why this different?
I have two MS SQL database. They are the same database. but made in different time ( 6 ms ago) and different version of MS SQL server. One is made MS SQL 2008, another one is maded in MS SQL 2008 R2
When I compare them, I see the following is strange.
One database showing the following for table ABC
[name] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_
Another database showing the same table and same field as
[NAME] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_
Why NOT NULL becomes NULL???

hi
one table was created with the column constraint NOT NULL
and the other made with no constraint that's all.
you can change the constraint on any of the tables as long as the data is correct
for example change the NULL to not null as long as you don't really have any nulls in the columns.
or on the other hand change the NOT NULL column to NULL.

I want to know if the default setting to NULL or NOT NULL is different for different MS SQL server version?
Where to see the default setting for column NULL or NOT NULL setting in MS SQL?
Why the same database for this field got change from NOT NULL to NULL as I've known we don't that change at all
This is important because our application is depended on it. I want to find out the root cause.

Perhaps someone changed it? But the bigger question is why not? What exactly is your question?
