declare @counter int
declare @statement nvarchar(max)
set @counter=0
drop table kua2
create table kua2(id int)
while @counter<307
begin
    set @statement = N'alter table kua2 add id'+CAST(@counter as nvarchar(max))+N' nvarchar(max)'
    exec (@statement)
    set @statement = N'alter table kua2 drop column id'+CAST(@counter as nvarchar(max))
    exec (@statement)
    set @counter=@counter+1
end

alter index all on kua2 rebuild

dbcc cleantable (0,'kua2',0)

alter table kua2 add id0 int
alter table kua2 add id1 int
alter table kua2 add id2 int
alter …
