I have a database full of user. This is roughly how the database looks:
| username | sex | birthdate | zip_code | |----------+-----+------------+----------| | coolUser | M | 02-14-1987 | 90210 | | blueUser | F | 06-16-1982 | 10011 | | . | . | . | . | | . | . | . | . | | . | . | . | . |
A user will be able to search the database for another user based on their sex, age and distance. I have another database with a list of zipcodes in the U.S. along with with their latitude and longitude. I have written distance function where it calculates the distance of 2 zipcodes based on their latitude and longitude values. I understand I can sort the users by sex and age by something like this:
SELECT * FROM userList WHERE sex = 'M' AND birthdate > 4-12-1986
Which brings me to my actual question: Is there any possible way to calculate the distance of the 2 users via an SQL query? Or do I have to sort the user based on age and sex first and then get that list and then filter it by distance? If I go with the second method how do I properly display the first 10 results, and have a pagination feature?
