I think I understand what you are asking. This will generate an update statement for each column in your table that will set it’s value to 0 if it’s value is null.

declare @tableName nvarchar(100)
declare @querys varchar(max)
set @querys = ''
set @tableName = 'YOUR TABLE NAME HERE'

select @querys = @querys + 'update ' + @tableName + ' set ' +
QUOTENAME(t.[name]) + '=0 where ' + QUOTENAME(t.[name]) + ' is null;'
from (SELECT [name] FROM syscolumns
    WHERE id = (SELECT id 
        FROM sysobjects
        WHERE type = 'U'
        AND [NAME] = @tableName))t

select @querys

execute sp_executesql @sqlQuery
