Alphabetical fetching from an SQL Query

Question

Hello,
When I fetch from the following query:
v_sql := 'SELECT REFERENCE_NO, COMPANY_NAME
FROM CONSULTANTS
ORDER BY COMPANY_NAME';
The company names are in alphabetical order
Something like:
A
B
C
D
etc..
Z
then AFTER the capital letters come the a, b c
Z
then
a
then
b
etc..
Is there a way to have the lower case letters such as "a" come right after ALL the "A"s
Then the b's come after the B's
Thanks
Doug
