Answer 1

You need dynamic SQL for this, such as:

declare @sql nvarchar(max);

with t as (
    select 'FirstName,LastName,SSN' as value union all
    select 'Address1,City,Zip' union all
    select 'HomePhone,CellPhone'
   )
select @sql = (select 'create table'+CAST(seqnum as varchar(255))+' ('+REPLACE(value, ',', ' varchar(255),') + ' varchar(255)); '
               from (select t.*, ROW_NUMBER() over (order by (select null)) as seqnum
                     from t
                    ) t
               for xml path ('')
              )

exec sp_executesql @sql;

尝试这个，

1. Select FirstName,LastName,SSN into Table1 from #InputTable
2. Select Address1,City,Zip into Table2 from #InputTable
3. Select HomePhone,CellPhone into Table1 from #InputTable
