How to delete all addresses saved in system

hi there. the system has been saving all addresses since we opened in May. this is causing delivery issues as customers are being allowed to enter previous addresses used that are saved to the system before we realised we can make certain parts mandatory.
is there any way to totally delete all the addresses that people have used so that they must enter a full address going forward?
thanks in advance

You can delete data from manually from the following table using sql command
1. dbo.CustomerAddresses table data
2. And then dbo.Address table data

hi sorry, I should have stated, I am a user not a developer. I have figured out a way to delete them I just have to do it manually which is no problem.
I cant seem to find the page where you can edit what is mandatory at the checkout....could you let me know?
many thanks!

I think it would better if you take help from a developer.

ok thanks v much

I don't recommend using SQL to 'delete all addresses'.  The Orders have a link to 'copies' of the customer address used at the time of order.
