Hi guys

Is there any way that I can order a column in the order 1,2,3 instead of 1,11,12,2,3,30.  I am trying to write a script using SQL.

select lpad(column, 20, '0') sorter, ...
from table
order by sorter

That happens because your column is varchar.
You have to use a numeric field or convert the column to numeric when running you query

select *
from table
order by cast(Yourcolumn as int)

why that? you can write like;
select thefield1youwant, thefield2youwant, thefield3youwant, thefield4youwant FROM table
much faster.

Oh,

Hello my Friend,
You can convert your field to numeric format in order part like this:
Select Field1, Field2 -- or some fields that you need
From ATable -- assume ATable is your table
Order by Cast(Field3 as int) -- assume Field3 is your ordering field

hey, my comment works too !

if you left pad a column with 0's it's sorted as a left padded string with 0's
