Why SQL query returns empty result?

Question

MySQL

SELECT t1.email, t2.stat, t3.home
FROM `user` AS t1, `analytics` AS t2, `adress` AS t3
WHERE t1.id = t2.uid = t3.uid

Answer: mysql returned 0 rows, although I know for sure (checked manually) that all 3 tables have rows where the id of the first is 61 and the rest have the same value in uid

Answer 1

maybe anywayWHERE t1.id = t2.uid AND t2.uid = t3.uid
