Hi,
I am looking for a stored procedure like sp_msforeachtable that by using it set all null values to default,
I mean all columns in all tables in a database.

Execute this Query and run the result set

select 'Alter table '+o.name +' add constraint DF_cont_'+o.name+'_'+c.name
+' Default null for '+c.name
from sys.objects o inner join sys.columns c on c.object_id=o.object_id
where o.type='u'

Thanks, your idea is great but I was looking for this:

select 'update '+o.name +' set ' +c.name +'= default '
+' where '+c.name+ ' is null'
from sys.objects o inner join sys.columns c on c.object_id=o.object_id
where o.type='u'

Then you need this

select 'update '+table_name +' set ' +column_name +'= '+column_default
+' where '+column_name+ ' is null '
from information_schema.columns
where column_default is not null
and objectproperty(object_id(table_name),'istable')=1
