从今天起检索加入日期少于 15 天的行

Question

Mysql query is

SELECT 
    userid as uid, 
    CONCAT( firstname, ' ', lastname ) AS name,
    profileimage,
    joining_date, 
    role as designation
FROM pr_users_details
INNER JOIN pr_users ON pr_users.id = pr_users_details.userid
LEFT JOIN pr_userroles ON pr_userroles.id = pr_users.userroleid
WHERE joining_date > DATE_SUB( NOW()-1 , INTERVAL 15 DAY )
ORDER BY pr_users_details.id DESC

I am getting these results which are a year old. I want to display new hires , ie todays date - 15 days. Am i missing something.

Answer 1

You should store date/times as date times, not strings. For the comparison to work, you need to convert the value to a string:

WHERE STR_TO_DATE(joining_date, '%d-%m-%Y') > DATE_SUB( NOW()-1 , INTERVAL 15 DAY )

However, you should fix the data:

update ?  -- whatever the table is
    set joining_date = STR_TO_DATE(joining_date, '%d-%m-%Y');  -- this will convert the date to a canonical format

alter table t alter column joining_date date;
