I have a column named streetaddress that contains
<Street Number> <Street Name>
for example:
15 rue Gontier-Patin
4968 Hillcrest Circle
how can i remove the numbers from the beginning of the row purely in sql?

This is based on @Paul Dixon above but is just for returning results without updating the data for things like sorting:
SELECT IF(address REGEXP '^[0-9]', SUBSTRING(address, LOCATE(' ', address)+1), address) AS addrSort FROM table;

I think this should do the job on the basis that each entry has it's street address seperated from the house number by a space (" ");
UPDATE table
SET streetaddress = MID(streetaddress, LOCATE(' ', streetaddress) + 1);
I've tested this and it works fine.
You can also use the following if you'd like to extract the house number to a new column previous to the update;
UPDATE table
SET housenumber = MID(streetaddress, 1, LOCATE(' ', streetaddress) - 1);

MySQL does not have regexp replace functions so it depends on the values in your column. If the string always begins with a number and then a space, you can do it with the SQl query Paul Dixon posted (doh, he was faster than me :D ).
If you need regular expressions to solve it, you have to do it in application code outside the database.

How about something like this - trim off everything up to and including the first space in strings which start with a number
UPDATE mytable
SET addresscol=SUBSTRING(addresscol, LOCATE(' ', addresscol)+1)
WHERE addresscol REGEXP '^[0-9]';
