Question

我有一个数据库情况，我希望按用户年龄范围获取用户个人资料行。

这是我的db：

table_users
username     age     email                     url
pippo        15      example@example.com       http://example.com
pluto        33      example@example.com       http://example.com
mikey        78      example@example.com       http://example.com


table_profiles
p_name       start_age_range      stop_age_range
young        10                   29
adult        30                   69
old          70                   inf

我使用MySQL和PHP但我不知道是否有一些特定的tacnique来做这件事，当然，如果可能的话。

# so something like:
SELECT *
FROM table_profiles AS profiles
INNER JOIN table_users AS users
# can I do something like this?
ON users.age IS BETWEEN profiles.start_age_range AND profiles.stop_age_range

Answer 1

Select
  *
From
  table_profiles As profiles,
  table_users As users
Where
  users.age Between profiles.start_age_rage And profiles.stop_age_range

Answer 2

怎么样？

    SELECT *
    FROM table_profiles AS profiles
    Where 
 users.age >= profiles.start_age_range AND users.age <=profiles.stop_age_range

获取具有两个列值之间的值的DB结果
