Outline number sorting

SQL Apprentice Question
Is there a way to in SQL to sort outline numbers to retain the
"natural order" state?

E.g.:


1.1
1.2
1.3
1.10


Shows up now as:
1.1
1.10
1.2
1.3


Is there any way to use recursive functionality to check for longer
outline numbers (i.e., like 1.1.1.1.1)?

I use this system in my books and other things a lot. My solution is
to pad each section with leading zeros and hope I never have more than
99 headings.

00.00.
01.00.
01.01
01.01.02.
etc.


You enforce this with LIKE predicates and ORs in the DDL rather than
trying to do it in the DML.
