Two tables:
table_a
-------
table_a_id: (primary, int)
table_b
-------
table_a_id: (index, int, from table_a)
table_b_value: (varchar)
A one to many relationship between table_a_id and table_b_value.
Given a query like this:
SELECT DISTINCT(table_a_id) FROM table_a
JOIN table_b ON table_a.table_a_id=table_b.table_a_id
I want to order by the number of occurrences of table_a_id in table_b. I'm not really sure how to write this in MySQL.

# startpoints = [0,10,20]
count values in range [0,9]
count values in range [10-19]
output = [9,10]

What's the best way to get a ul to start from 'x'?
The start tag is depricated and everything I have found on Google has used the :before pseudo class which doesn't work in IE6 or 7. Didn't have much luck when searching stack either.
Only thing I can think of is manually go through and number the lists myself and style accordingly?
Any help appreciated.

Thanks!
