Answer 1

You can use a loop in store procedure but best way is you check all column for null value because may be any column have various data type.

i hope this be helpful .

Answer 2

Update Table1
set col1='0'
where co1 is null

And so on...

Answer 3

You can update as stated above but if you need to have a default field as 0 then you should have used default on table creation

CREATE TABLE dbo.Something
(
    id               INT IDENTITY(1, 1),
    col1        INT DEFAULT 0
)

but if its legacy code than on insert proc you could have used like

CREATE PROCEDURE [dbo].[spa_CRUDSomething]
    @flag CHAR(1)
   ,  @col1 INT = 0
AS 

Usually the problem isn't in doing fixes rather on way of fixing the fixes
