I have a table which looks like

Col1    col2 col3 col4 col5
1 5 1 4 6
1 4 0 3 7
0 1 5 6 3
1 8 2 1 5
4 3 2 1 4

The script is

declare @t table(col1 int, col2 int, col3 int,col4 int,col5 int)
insert into @t 
select 1,5,1,4,6 union all
select 1,4,0,3,7 union all
select 0,1,5,6,3 union all
select 1,8,2,1,5 union all
select 4,3,2,1,4

If I do a sorting (ascending), the output is

Col1 col2 col3 col4 col5
0 1 5 6 3
1 4 0 3 7
1 5 1 4 6
1 8 2 1 5
4 3 2 1 4

The query is

Select * from @t
order by col1,col2,col3,col4,col5

But as can be seen that the sorting output is wrong (col2 to col5).

Why so and how to overcome this?

Thanks in advance
