I have 3 different tables: user_reg, user_contacts and contacts.

I have the following SQL statement that returns all the user_id's that I am interested in using:


SELECT user_id FROM user_reg WHERE year='2012' AND end_date IS NULL


I then need to use the returned user_id's to query the user_contacts table to find all the contact_id's where the user_id matches the results of the previous sql statement. e.g:


SELECT contact_id FROM user_contacts WHERE user_id='From Above User_ID'


Now that i have the contact_id, i need to select email, phone and mobile data from the contacts table where the id matches the previous contact_id. e.g:


SELECT email, phone, mobile FROM contacts WHERE id='From Above Contact_ID'


Without doing this within multiple while or foreach loops, is there any way to combine these three statements into one so that the results are returned as one?

Thanks
