INSERT INTO `users` (`ID`, `number`, `password`, `confirmCode`, `pic`, `name`, `gender`, `link`) VALUES
(50, '5105858953', '81dc9bdb52d04dc20036dbd8313ed055', 73485, NULL, NULL, NULL, NULL),
(52, '4086672806', 'eeafff918f30a0d33ed9a3f4073d5be6', 89290, NULL, NULL, NULL, NULL);
Or should i use one table and have an extra field in users that contains all their contacts and custom names of that contact like such
123-530-2340:Bob;555-402-1323:Billy;555-419-2301:Joe;
What are the benefits of each and which should I use if I want reads to be fast
